Code is free, parts cost money/take up PCB space/break/etc. Switch debouncing in software is easy, free, and can be made into a function or subroutine to be called any time you need it, no matter how many switches you have to debounce. Remember my mantra: The ideal hardware design uses zero parts. You may not make it there, but the closer you get the better off you are. 8-) 73, Dale - N0XAS -- It's a thankless job, but I've got a lot of Karma to burn off.

If the switch bounce is pretty high frequency, you can pretty much squash it with a cap. However, many switches bounce for quite a long time, and the cap may do more harm than good. The best thing to do is to look at it with a scope. If you can dampen the excursions quickly then it may be a help. But a couple lines of code are always cheaper than a cap, so unless you are really pressed for space in your application I wouldn't even bother. Also look at your app. Again, in many cases some switch bounce isn't a big deal, and you don't even need to bother with the debounce code. 72/73 de WB8RCR http://www.qsl.net/wb8rcr didileydadidah QRP-L #1446 Code Warriors #35 ----- Original Message ----- From: "Rich Johnson" To: "Low Power Amateur Radio Discussion" Sent: Friday, February 27, 2004 6:30 PM Subject: de-bounce > Given a push button that grounds a pullup that is input to a PIC pin is it > help the switch bounce if a 0.001uF cap is connected between the switch?

I can only get a good test on it in read as that is working and FPP doesn't shut down with the error.

I'm assuming you're talking about=20 the QRP-RF PCB ASSY (RF board). On that board, Q2 is a 2N5109 and Q3 is a= =20 2N5179. If memory serves, I popped the 2N5109 once... You really don't=20 want to replace the 2N5109 with a 2N2222 as Q2 runs hot as it is... Assuming you're talking about replacing a MPS5179 with a 2N2222, from an=20 "absolute maximum ratings" standpoint (see below), you should be just=20 fine--the 2N2222 exceeds the MPS5179 ratings in the most critical=20 parameters. So it probably "won't blow." Most importantly, the 2N2222 has= =20 a higher power dissipation (and if its a driver, the Index drives its=20 drivers pretty hard). However, the MPS5179 (2N5179) is significantly lower noise, and its Ft is a= =20 good 3 times higher. The minimum Ft of the 2N2222 is 250, according to the= =20 Philips datasheet. Using "Good Engineering Practice" (or W1FB, which is, I= =20 guess pretty much the same thing), you want the Ft to be 5 times the=20 operating frequency of the amplifier. Q2/Q3 is the IF amplifer, running at= =20 the 50MHz IF, so you're right in there with that parameter, and the minimum= =20 DC gain (hFE) is actually higher in the 2N2222 (but of course, with a=20 900MHz fT the 2N5179 is a much better VHF transistor). The biggest consideration is the noise factor. So what may happen is that= =20 you may actually raise the overall noise factor of the Index, which for the= =20 same bandwidth, will lower the minimum discernable signal--per EMRFD, MDS=20 (dBm) =3D -174 dBm + NF(dB) + 10 log(B), where B is bandwidth in Hz. So, it'll probably work (and sounds like it does), but if you want the same= =20 performance as before, I'd order another 5179 and put it in, since it is in= =20 the 50MHz IF. Might be OK, might not. YRMV. An interesting exercise,=20 however, would be to measure the MDS with the 2N2222 in place of the=20 MPS5179.

If I am doing my math correctly, this will be my 48th trip out on the AT with QRP radio. Yep, for the past 48 months I have been going out to the AT once a month no matter what the weather conditions were. My first trip was in March 2000. So the warm temps will be a great relief. I took a hard fall on Tuesday on the snow and ice. I landed on my knee, so this will be a test to see how the knee feels. I might hike in a few miles, not really sure. I plan on leaving the home QTH around 13:00 UTC. I could be on the air around 15:00 UTC. I will have my K1 on 40, 30, 20 & 15 meters. I plan on using WA3WSJ's VBWFPA vertical for 40, 30 & 20.

Originally i had 6 'AA' NiCad batteries in my KX1 but i needed more power for pedestrian mobile operation. i removed 4 of the 'AA' NiCad batteries and added 8 - 1/2'AA'-250 short type to boost the voltage to 14 VDC. That raises the output power to 3 Watts. The operating time is about 3 hours on a full charge (depending on your speed and number of "Q's).. These batteries are available from Batteries Plus. They have flat contacts so they need to have a little solder blob added to the + terminal so they will touch each other when in series. These 1/2 AA 'short' batteries (250 mAH) are 7/8 inch long. There is a longer 1/2 'AA' battery that is 1.2 inches long and it won't fit the battery holder. ps: If you make any modification to your KX1 it will void the warranty... --------------- Here is a way to charge the 1/2AA NiCad's without taking the KX1 cover off. (This is not suggested if you are only using primary L91 Li batteries). Here is the modification i made to my KX1. i installed a small 2.5 mm mono phone jack to the lower corner of the battery chassis. You have to drill hole in the chassis. The jack goes right below the auxiliary DC connector J1. This jack has a NC switch built into it so when you plug in the charging plug the batteries are disconnected from the radio and the charging voltage only goes to the battery even if the radio is turned on. The connections are: black wire to the jack ground pin, red wire to the center pin and the NC switch wire to the red wire of J5-1. Now you can operate the KX1 from the auxiliary DC connector while charging the internal batteries through the new charging jack. This modification allows charging internal batteries without taking the unit apart. You can also monitor the battery voltage through this connector. The charger can be any wall transformer that puts out about 18VDC open circuit. The charging current for the 1/2AA NiCad batteries is 50 ma for 5 hours. You will need to insert a resistor in series with the transformer to limit the charging current. They don't get hot at 50 ma. --------- Here is another KX1 battery switching modification. The current design "AND's" the internal battery and external battery sources together using 2 diodes. If your external battery voltage goes below the internal battery voltage, the internal batteries will start draining. i left my KX1 on for a few days and after i ran down the external battery and the internal batteries took over and became discharged. These were the expensive Lithium "AA" Primary batteries (L91's). i wanted to save the use of these Li batteries for special uses like Pedestrian Mobiling: See the w0rw/pm KX1 report on the Adventure Radio Society web site at: http://www.arsqrp.com/ars/pages/back_issues/2004_text/0204_text/W0RW.html Here is the DC J1 switching Modification: The DC Power connector has an unused (normally closed) switch. This modification will use that switch so that when an external power source is connected the internal batteries will be disconnected, and conversely when the DC power plug is removed the internal batteries will be reconnected. Open the unit on an ESD grounded work station. Separate the battery compartment by pulling the battery connector (J1) out. Cut the 2 traces that ground P1-2 "-" (getting scary now)...Top Side.. Now add an insulated jumper wire from P1-2 "-" to the side contact of J1 (J1 is the power connector), The unused switch contact is soldered to an isolated pad just the left of the marking 'Z2'... That's it.... Now you can protect those internal batteries. One other thing that you can do is to set the LED Display Control to "INF" then the LED display will act as a pilot light. 72 de w0rw Paul w0rw@aol.com ------------------------------ Date: Sat, 28 Feb 2004 08:54:36 -0600 From: kd5kxf To: "\"Low Power Amateur Radio Discussion\" " Subject: [169187] Bacon Bits March issue Message-ID: <200402280854.36587.kd5kxf@classicnet.net> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Content-Disposition: inline Howdy folks... thought I would throw this out before ya'll turn out the lights and leave.

Naturally enough, more holes is more money. So then we get to SMT, where you ain't got as many holes & the parts is tinier. Which explains the NorCal SMT kit & the tendenz for going to SMT parts. Which is a real mess when you have a head cold and start a ten-minute sneezing jag smack in the middle of inventory for a new kit or whatever. And then we get to beta-blockers so your hands (ok, so MY hands) won't shake. Stupid hippies. Anyway, I'm closing in on checking my work again so I can get this tiny board pitched at my door in an envelope with three or four days turn-around time. Just for fun. And because it was Cindy's payday yesterday & I ain't spent my obligatory share yit. But I come up against the number of holes limit for the cheapo-check your work boards that I've been playing with. And no, I ain't got back to the TDA1072 yit 'cause I'm hung up on this obsession with a tiny radio fits in yer pocket, see? The plan was to put a little board on the edge what I can chop off & use as a op-amp CW fliter. That works fine 'cept I'm two holes away from the limit, so I can't double 'em up like I do the radio board. It's a complicated story. But anyway, I find myself looking at doing the fliter as an SMT thingie. I have the tech data for the packages &c, but I'm also not too keen on getting involved in the sneezing jag thing once I finally get medicated enough so my hands don't shake & I ain't wild-eyed with urgency to see if it all works in the third place. At which point I'm thinking I better just cool my jets & go with the flow, so to speak, 'cept I ain't using one of them flow-slobberin' machines. Just a blunt-ended old slobberin' iron & a lot of restraint. Patience ain't my forte, see? But I can say that the receiver hears well enough to satisfy even my hungry-for-lots-of-audio ears. And I got about half a watt out of the beast this morning, multiple slobberin' and parts errors included. Maybe I have all the circuit errors all sorted out by now, eh? Yeah, right. Stupid hippies. 73 Nils . . . and when I'm done with this 'n project? well, you know there's always more . . . I'll have a couple four or five extra boards, just in case . . . ---------------------------- Nils R.

I appreciate any help you may be able to provide. It's almost March so I'm thinking that a spring project - once the weather warms up - for me will be to replace my antenna feedline. I am using a 40 meter Windom antenna and am feeding it with RG-8. This feedline is several years old and my question is how can I tell if it needs replacement? Here are some facts, to help you understand my specific situation: 1) I can easily access the antenna end of the feedline, it is connected to the Windom by a UHF connector which I can unscrew. 2) I have some test equipment including a DMM and a generic version (I think "Vectronics") of the MFJ antenna analyzer. 3) I'm not sure what I am looking for, other than a direct short or an open line. 4) I really have no reason to think that the RG-8 is bad, but every time the bands are dead I scratch my head and look at the antenna to see if its still there. 5) I realize that RG-8 probably wasn't the best choice, but it is what I have, so if I replace it, I'll get something better, but if it doesn't need replacement I don't want to, naturally. If you'll need any more info, please let me know. Thanks in advance for any help you might provide. Tom McCulloch WB2QDG If only God would give me some clear sign!

I don't have the formulas at hand but they should be online. Look for companion software for the antenna analyzers. Remember that feedline loss makes the SWR look better than it really is. You can put a known resistor at the antenna end (say 200 ohm) and then measure the SWR at the feed end. The lower the SWR, the more loss there is in the cable. If you used a 200 ohm resistor the best would be a measured SWR of 4:1. This would show the lowest loss. If you measure a SWR of 1:1 then the loss is probably WAY high and the coax should be replaced. If you do this measurement on your feedline when new then you can simply compare measurements and see if the coax is failing. This also allows you to measure the loss at the frequencies you use. michael N6CHV Tom Mc wrote: > > Hi gang, > 1) I can easily access the antenna end of the feedline, it is connected to > the Windom by a UHF connector which I can unscrew. > > 2) I have some test equipment including a DMM and a generic version (I > think "Vectronics") of the MFJ antenna analyzer. > Tom McCulloch > WB2QDG ------------------------------ Date: Sat, 28 Feb 2004 12:34:49 -0600 From: "George, W5YR" To: "Tom Mc" , "Low Power Amateur Radio Discussion" , Subject: [169192] Re: [QRP-L] Elmer Question: Antenna feedline (long) Message-ID: <002f01c3fe29$939cd8f0$0402a8c0@PS> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Tom, coax problems usually involve (a) connectors and their attachment to the line and/or (b) increased line loss usually due to moisture getting into the line and corroding the shield. Very old coax might also suffer from UV effects such that the polyethylene dielectric has changed properties and increased its contribution to line loss. Checks of the line should include a close visual inspection of the connectors and the solder joints to the coax at each end. The effects of moisture and/or UV exposure can be checked by measuring the loss of the line and comparing it to the expected loss based on published loss in dB/100-ft. Of course, ohmeter checks for shorts and opens should be made if feasible, although it is unlikely that a line that has worked for several years has suddenly developed a short or open, unless a poor connector joint is involved. A more direct though invasive check for corrosion is simply to remove some of the outer covering and examine the braid directly in the vicinity of the connector at the antenna end. Any signs of corrosion there usually indicate that more is present along the line and it should be replaced. Line loss is easily measured with a wattmeter if you have or can borrow one. The procedure is to first measure the power delivered to a dummy load from the transmitter (any convenient power level will work but let's use 100 watts as an example) connected by a short length of known good coax. Then connect the coax to be tested to the transmitter and move the wattmeter and dummy load to the antenna end of the coax. Repeat the test measuring the power delivered through the coax to the dummy load. It is important that the transmitter power output not change while this test is being done. Armed with the two power values (one at the line input and the other at the line output) a subtraction of the smaller from the larger gives the measured line loss in watts. Now, we get a little technical. The specs for your RG-8 give matched line loss in dB per hundred feet. You need to know the approximate length of your line which you divide by 100 to find the loss in dB for that actual line length. That is what presumably good new coax would do. Now to find your measured line loss in dB, use the formula dB loss = 10 x log(Pi/Po) where Pi is the input power - say 100 watts as an example Po is the measured output power - say 90 watts The power ratio Pi/Po is equal to 100/90 in our example which is 1.111. Using a calculator, find the log of 1.111 which is.0.0457. Multiply by 10 to get the line loss as 0.457 dB. The matched loss for RG-8 (Belden 8237) is 0.662 dB/100 ft at 14 MHz . Now, let's assume that your line is 50 ft long. You can measure the line length with your antenna analyzer if you don't know it. So you would expect the loss for new, good RG-8 to be 0.331 dB. Your measured loss is 0.457 dB which is 0.127 dB larger. So, now comes the judgment part. How important is an added matched line loss of 0.127 dB? We would expect that such a small fraction of a dB is likely to be relatively unimportant. We know immediately that since it is a small number that there is nothing seriously wrong with the cable and connectors. Corroded coax or poor connector joints usually show larger losses. To put it in perspective, if you input 100 watts to the line then the expected loss of 0.331 dB represents a power ratio of 100/Po, so we need to solve for this value of Po. With our calculator we solve the equation 10^(0.331/10) = 100/Po or Po = 100/(10^0.0331) = 92.66 watts But we measured 90 watts of actual Po, so we know that the coax has an additional power loss of 92.66 - 90 = 2.66 watts. This is 2.66% of the input power of 100 watts. Most folks would agree that an added loss of less than 3% is hardly cause for concern, especially since the wattmeter can be in error by that much or more.. Thus we can conclude that the coax is probably still in good shape, although showing possible small signs of deterioration. On the other hand suppose that we had measured only 40 watts output. Immediately we know that we have a loser coax since 60 watts is being dissipated in the line. This equates to a loss of 3.98 dB or over ten times the expected loss for good RG-8. If the connectors check out, then something is wrong with the line itself and replacement is indicated. I have known coax to be good after 30 years in the sun and weather. So age is not always the criterion. On the other hand, coax is relatively cheap, so if you have doubts and lack the equipment to make these tests, the easy way is just to run new coax. I suggest RG-8X for100 watts or less and RG-213 for QRO. I use RG-8X for all coax applications and find it to be very convenient with its smaller size and weight. I would advise against RG-174 unless the line is short and you need its small size and weight for some reason. All this has told you how to build a clock because you asked for the time. [g] But. I wanted to overview the steps involved in making this test since you posed it as an Elmer Question. Those get my attention! 73, George W5YR w5yr@att.net http://www.w5yr.com ----- Original Message ----- From: "Tom Mc" To: "Low Power Amateur Radio Discussion" ; Sent: Saturday, February 28, 2004 10:06 AM Subject: [QRP-L] Elmer Qustion: Antenna feedline > Hi gang, > I have an antenna question which is of an Elmer nature as I'm sure its > pretty basic.

(I was having trouble with TR Log.) Well, the post event processing was difficult to say the least. While the input during the 2 hours was OK, I could not edit on the fly. So I put the notes on a yellow pad on the desk. Fast forward to the day I posted the log to the QRP-L. I forgot to bring the yellow pad to work and I posted the unedited log anyway. BAD MISTAKE. I had about 15 notes on the pad and figured how bad could this be? Well, as has been pointed out to me, it was the worst initial log posting to date. One thing ACLog does it put the date at the end of the line and I could not see how to easily move it to the front without manually editing each entry, so I left it. I am sorry if this seemed very screwed up. If I ever do this again, I will fix it BEFORE sending it to the list. So thanks to N1TP, who got the times where they belong, here is the Rev 2 of the log. Again, I do not have access to the new list so I cannot post there.
