Maybe not very likely, but perhaps check the 0.015 ohm current shunt resistor to make sure it's not open or that there's not a bad solder joint on the board? I.e. make sure there's power to the final
FB on the troubleshooting Bill. Sometimes it's the simple stuff that gets overlooked and causes hair loss. An local friend of mine told me about picking up an old TT (Omni or Corsair?) at a hamfest f
(*"SSB" = "Solid State Boatanchor," my lighthearted but respectful term for the old Omnis, Corsairs, etc. which take a lot of desk space with the matching PS and external VFO.) Given the frequent thr
If they are the 252 series they use common parts and should be easy to repair. The caveat is if they don't have the optional crowbar (also easy to clone), it is highly recommended that you add one as
Go look at the archives of this list. There is a cottage industry devoted to keeping vintage TT gear running popping up, including efforts to produce replacement boards for those boards which have "u
Allen, The OVP is not "rocket science" so to speak - it's just a zener diode, a heavy-duty SCR of the proper rating, a fuse, and a few passive components. It should be fairly easy to build one on a b
Allen, I think the 8 pole filter you want is the 2.4(?)KHz model 220. The other item (well documented elsewhere) is that the AC feed from the 225 to the front panel switch can cause hum pickup in the
"[D]sp brick wall narrow filtering"? I've had the same thing happen back when I was running a Corsair with the 250 Hz 282 filter switched in. I remember several occasions when I'd sign off a contact
(Reminded by the "Restringing the Model 200 VFO" thread) Looking for the "department of antiquities" here: my 505's dial calibration is off, all bands. According to the manual everything derives/mult
For < 100W I'd say perhaps a z-match or homebrew link coupled tuner. (The link coupled ones can be fairly simple if you don't mind moving coil taps etc. to change bands.) That being said, I'll let th
TT did make an optional crowbar board for the 252/262 etc. supplies. As I recall (my dad had several 252s over the years) it was a board that mounted inside the back panel of the PS and should be pre

Watch for an "expiration" date on software in the future? How about now? There are a number of (software) companies doing that already. "Will the Ten-Tec of the future be any different?" Unless they
For $50 you definitely got your money's worth. BTW here's a link to info/manual on the 405: http://wa2iac.com/gear/QRP/Ten_Tec_405_QRP_Linear/index.php It appears that the connector is a 4 pin Jones
Don't get me started - most people don't realize how much sleight of hand goes into advertising in general. Without naming the time or place other than to say it was quite some time ago, a window/sid
I think it's good to discuss this as a "real world" exercise in knowing what the competition is doing. To sell a radio to a non-brand loyal ham, TT has to be aware of things like Sherwood's chart in
