It came out of some kind of Thyratron RDF unit made by "Pacific Division" (Bendix?) Anyway it is a model LD-1D and runs on 24V DC at just 1.2 Amps! Produces 350V DC at 40 mA (maybe a tad more too!) Complete with nice shock-mounts. Looks clean! Price is - $0.00 plus shipping from Maryland 20877 Weighs in at about 5-8 pounds I would guess.

There were a lot less of the 22 sets made however, but they were pretty similar. Take a lok at my web site for the addres of the guy in Canada. He actually has a catalog and sells all of the accessories for the 19 set too! It was a venerable 807 rig with about 10 watts of AM! Pretty rustic actually! Not a s good as the ARC-5 and about 4 times the size. A lot of British hams used them in the 1950s.

I dug through my junk box and came up with an interesting freebie. I don't have tons of stuff, but I DO have these! I have 3 sets of the following to give away. I have fair number of them, but don't need as many as I have. Qty. 3 6DK6 7-pin (looks like 6AU6-size) Qty. 3 35EH5 7-pin (looks like a 6AQ5) Ya get 6 tubes, all new. (NOS anyway) I'll even cover the postage for all 3 sets. One set of 6 tubes per person till all 3 sets are gone. Here's the catch: Ya have to come up with a circuit that I CAN USE these darn things for! (No offense, McAulay ;-/ )! Like a little 2-tube regen, speed keyer, transmitter, booster for a D-104, or something! My RCA book doesn't list them (it's too old), but they're pretty generic. Let's hear from the old design folks, eh? If ya want 'em email me. Dave WB7AWK Tacoma, WA

Hi Bob, it's been a long time since I replaced one of those little "doorknob" tubes...I think about 20 years. But, I can tell ya they were a stable amp..used in line regulators and terminal amps for the WE L1 coax carrier system. We went thru them like crazy...I did the mtc for all the regs and amps on the line from Seattle to Yakima, Wa. It was put in service in late 1947, using bays from Cleveland OH and Chicago, Ill. The carrier was 600 voice channels and ran on buried, 4 tube coax. Each coax was 0.375 in. in diameter, glass bead spaced and had the tubes surrounded by paper insulated, 19 ga pairs used for voice, along with two 16 ga program pairs. These were used to bring the first TV audio to the "wilds of Eastern Washington". The video feed was placed on the spare tubes, back in the days of black and white networks and then fed to the local TV stations in that area. The entire bundle of tubes and pairs was wrapped in jute and paper, covered with lead sheathing and then over that layer went two layers of 2 in. spring steel tape, with two layers of tar impregnated jute on the outside of that. When the cable was buried, it was put in to what we called "Government Standards" for the time...in other words it was backhoed, plowed and blasted down to 48 inch depth for the entire route. The system consisted of a line repeater every 7.4 miles, placed in a concrete block building, and powered by an 1800 volt power loop on the center conductor of the coaxes that could run up to 10 repeaters. It was spooky gear to work on with that kind of voltage ...one fault in the wrong place and everything was hot. Each tube had 4 pilot freqs on it, 64, 556, 2064 and 3096 khz, and these were monitored by the regulators, adjusting line gain with the amps in each mounting with the regs to keep overall levels constant. The 2064 was the overall line level pilot, and was what the 102A's were used to amplifiy. It seems to me the 101A was a triode and the 102 a tetrode.. So...that's what the 102A was made for and how it was used in the phone racket. Have fun 73 Doug, K7YD Livinston, MT BOB DUCKWORTH wrote: > > Looks like a little golf ball with legs. > WE102A. > Couldn't find in my RCA book or on web or usenet archives. > -bob

(it wasa advertised as working ok) Reason I got it was had no luck at all ( and it was to darn big and heavy) restoring the sx101 I got. It needed a complete alignment and I did not have the test equipmenty to do the job, so sold it for what I had in it.

I have one of the things, and everyone who has ever used it (I used to lend it out to new novices) thought it was just fine (but then, what do they know? hehehe). The HW-16 receiver is a fairly sanitary superhet with a bandwidth that's really a bit too broad -- or maybe a LOT too broad -- to satisfy most CW ops. But it does work well when working, and it ought to be just fine for you at least for a while. Congratulations on the new gear! 73 John

Whew..... dunno if I wannbe near that fish..... > I have worked a couple of guys on there... > VA3RP, K2RMQ on 5/15/97 I have worked Rod/VA3RP several times, and last nite had the good fortune to work our illustrious listleader Conard/WS4S/8 from the motelroomwiththe sneakysnakewireoutthewindowandupsomewhare and his AN/GRC-109.

Keep yer tin cans on fer da crewe --- they be about if ye slips inta da tin a little......in the old days, the marke of a CW chops was how far he could slip into his tin cans an git dwn in da QRMud ta dig out da weak ones..... 73/ZUT DE NA4G/Bob UP p.s. Hint for the day..... If youse chops can muster up a JANuine LS-166 or equivalent tin diaphram speaker, as used in govt. work by the green-clad boyz, set it down on its backside, and cuts ye a piece of black PVC pipe (or white or wooden tube or cardboard tube or bakelite tube, or whateveryegotstagetdapicture) roughly 1R5 to 2R0 inches in diameter or a little more or less, and roughly the length of a gentlemen's cigar (anywhere around 5-10 inches cut to resonate) making sure it resonates at the desired sidetone QRG, and then set it on small thin feet of some sort about 1/2 inch above the grill of the overturned speaker, in a vertical organ pipe resonance mode. It maketh one o' da finest CW filters ye ever did 'ear. Similarly, for the regenerator crewe, wat uses tin cans, take a similar sized tube and insert a spare tin can sized ta fit (I use a Trimm Dependable or Featherlite tin can) in one end and set it on its vertical to filter in a similar manner to the LS-166, above. Bothe worketh FB, in de ol' Man's shack. The design hails from a little filter from the early 1920's that used used a tin can driver in a tube like this with a doctor's stethoscope in the open end to act as the sound pipe directly to the ears. Works fine, too. That and a good regenerator puts the socalled Kenicoyasawhooies ta shame. Ancient tech at its finest.

Date: Sat, 17 May 1997 15:47:45 +0100 From: BOB DUCKWORTH <bob@atl.org> Subject: Amazing little 5 tube BA RX uses 5 tubes and they are all the same! Thought some of you guys might be interested in this little RX. It's a lot of radio for 5 tubes. Mosely CM-1. It's a 5 tuber employing 5 x 6AW8 (pentode/triode in the same hollow). It's basically a 4 tube 80m band RX with a one tube converter (triode mixer and pentode xtal osc) with preselector that can be switched in for the other bands. The triode mixer is touted as having lower noise than a pentode mixer and an advantage on 10m. The second 6AW8 is triode tuneable osc and mixer being a TRF on 80 and TIF on 40 - 10. IF is 455kHz with two transformers for selectivity. VFO runs 3955 to 4555kHz. The third 6AW8 pentode section acts as a 1st IF amp driving the 'S' meter and another transformer. It's triode section acts as the first audio amp. The fourth 6AW8 pentode is a second IF driving another transformer. These 4 x 455kHz IF transformers provide good selectivity and the RX is enjoyable to use on SSB and CW although I'll probably add an outboard 'Q' multiplier (hint, if you've got one in the junk box). It's triode section is used as a product detector. The final 6AW8 pentode is the second audio amp. It's triode is the BFO. AM detection is handled by a 1N34 with a pair of 1N54A employed as a basic ANL. Built in Bridgeton MO. - -bob wb4mnf

Well, I guess if you are used to a Collins mech filter at 200 Hz, 500 hZ (the HW-16) might appear to be too broad. Personally, I think it just fine...then again, I prefer the 2.1 kHz filter for CW anyway so I can keep track of what is going on nearby. :-) Ken W7EKB

Maybe two signals on both 80 and/or 40, nothing on 20. At 0530 AM PDT I heard someone on 7050. I was up in bed at the time. I had left the R-1004 on in the basement last night. Whoever it was, was S-9. I checked the end-fed lw to see if it had gotten cut off or grounded, or buried, and as far as I can see it is still up. All three receivers seem to work (HW-16, R-1004, SB-301). What signals I do hear are pretty weak. It even sound dead on the tri-bander. Of course it never did work very well anyway, but this is ridiculous!!!! Sigh........ Ken W7EKB BTW, was listening a few minutes ago to a Swap Net on 7240 kHz SSB on the R-1004. W6xxx. Lots of QSB on him and he was weak, but at least I could hear him. I still find the R-1004 to be a bit more sensitive than the SB-301. Shucks......
