Looking for a (used/reject/scratch/dent/etc.) top ("U") cover for 425 amplifier. Mechanically compatible (but not OEM) cover may also be useful. Existing amplifier here is currently somewhat immodest
My Ten-Tec Argonaut 509 (I'm not original owner; I've had it for a long time but only put it back in service earlier this year) normally puts out about 2W PEP/CW when powered by 13.8VDC. I was using
Need one (working) 10M module for Ten-Tec scout/argo (555/556); the module type number is 809. Have other band modules for Scout if you are interested in a trade. 73 Dave WB0GAZ wb0gaz@yahoo.com
I have a ten-tec 1210 transverter first obtained as a swapmeet basket case some years ago, which I have repaired and is now working normally as it was originally designed. I wish to modify it to acce
Think I finally figured this out - D6 is exposed to a high RF voltage during transmit, as the IF attenuator is really just R25 (the 50 ohm load clamped to the housing) and the action of the ALC circu
My Argonaut 509 (S/N 509-3xxx) has been in storage for a long time, and after unpacking it and putting it in line, I discovered the PTO (frequency dial, not the resonator rack) control is largely imm
Found that I had the ten-tec instructions in my file, so proceeded up to a point where I am stuck, so looking for advice: PTO subassembly housing (that holds the coil and movable parts) removed from
Thanks, Bob - my initial search on groups.io didn't use the correct search term - I'll wander over there shortly! Progress - the problem step (#4) was that ten-tec directed that the PTO setting be fu
Hi Ed, I got up to reassembly step 19 (bearings in place) and discovered that the vfo shaft was not transmitting enough torque to the core drive rod (not transmitting any torque counter-clockwise, so
Looking for a ten-tec scout or argo for a project, one that's ugly/modified/problems OK. If you have one and are considering sell/trade, pls e-mail. Tks, 73 Dave WB0GAZ wb0gaz@yahoo.com
Looking for scout or argo, will be used for experiment/project so can be modified, be ugly, can have dead finals, but otherwise should be working. Can use 10M module as well. If you have something al
Lost a cover from my Ten-Tec 1210 transverter project, have given up the search and looking to replace. If you have a dead TT 1210 or cover(s) in any condition, pls e-mail. Tks, 73 Dave WB0GAZ wb0gaz
Last week I happened into the round frequency dial disc Ten-Tec had sold with their MR-1 kit in ~1969-1970. Now I'd like to assemble the four (VFO, TX, MIX, AA) modules I've gathered over the years i
Hi Bob, Scanning the dial is a great idea -- I should have thought of that ;-) I'll do just that, get some dimensions, and a couple of JPG photographs to go with it. Should be able do that sometime t
Recently used an Orion II (on CW), receiving on bands crowded with many very strong CW signals (and a fairly large antenna). I noticed sometimes a condition where the receiver seemed to momentarily l
Thanks, Hank - I should have figured that out at the time (basically use RF gain control to keep out of whatever AGC loop/limiter is doing this) but so it goes. Anyway, no real need to do any extra r
Have a use 525 Argosy that doesn't have (maybe never had?) serial number on back panel (could it be inside instead)? Trying to figure out whether it would use the 223 NB (for SN < 825) or 223A (for S
