Oh boy it sure would help if I read the manual more closely, I was mistaken and thought the TX Gain was a carrier control instead of the MIC gain. Thanks Steve and Barry for clearing that up for me.

That sounds like normal operation. There has to be some signal being created in order to operate the VOX circuitry. If you’re using a non peak-reading meter, you should see the meter kick up a

Sounds like it’s working correctly. TX gain is just mic gain. 9 o’clock position is about where you start getting drive. The standard tune up process requires turning up the tx gain as the first

Hello to the group, I recently picked up a TR-4/AC4 and am trying to get them going. I have rebuilt the AC4 and replaced the can cap in the TR-4 along with a few weak tubes. I am able to tune the rig

My first transmitter was a Poptronics article. It had a single 6V6 tube functioning as both oscillator and amplifier. The final coil was wound on a toilet paper tube. The tuning indicator was a

Floyd, I had the same problem on my R4-C. I traced it to 3VPP of 60 Hz ripple on the +12v supply that powers the calibrator. That ripple, which was caused by an open diode in the power supply,

Yeah, mine also came with an RV-4C. If you want to operate real split, it is just the ticket but I rarely go after ATNO’s with vintage gear. I have gone after new band-countries. I’m currently at

I have two TR-3s, 10nnn and 12nnn serial numbers, and the gear immediately behind the lexan dial is metal.? The small gear on the shaft from the PTO is also metal but I think all of them are.? The

Though I no longer have a TR-4C, I always paired that xcvr with an RV-4C external VFO/spkr cabinet. Listen on one VFO and tx on the other - problem solved. Essentially gives you "rit" on steroids.

Thanks Gary, Now if I see a TR4CW, I know what's in store for me. 73 Jay gmail.com_at_groups.io_lastradioman@...> wrote:

I have bound QST from 1917 to 1972 (early ones are loose) and 95% of the CQ's up until 1965 or so. They still make good reading and quick reference. John K5MO [email protected]> wrote:
