My cousin was a ham, When he married and moved out of my GrandMothers house I found a collection of "Popular Electronics". This started me on the road to a ham license and my life'sn

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,

Mine is too Peter!! Ronnie

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 all the QST’s from the beginning to 1980 on CD. I also have all the 73’s in digital as well. At one point, I had a lot of QST, Radio Electronics and Popular Electronics and others that I

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:

Jay, All TR-4s and all T-4Xs shift the CW carrier, and its very close to 1KHz.? If you want to be on the other stations frequency, you need to tune his note to 1KHz. This offset is done by a

There’s no need to procure a complete PTO; someone who needs that should use it. ?The B-Line frequency dial is being delivered to me from response of qth.com advertisement. Thank you. 73,

Steve, Thanks. One more thing, RIT: Is yours the TR4CW-RIT, or do they all do this? 73 Jay W6CJ protonmail.com_at_groups.io_lastradioman@...> wrote:

They sure got a lot of mileage out of that design over the years. I too recall the ad, though CQ was my favorite mag. John K5MO [email protected]> wrote:

I tune for a received note between around 450 and 750 Hz, with the higher end being closer to where you'll both be on the same frequency. This is also where the signal on mine peaks within the narrow

Group, How do you operate CW using the TR4CW?.... zerobeating?....sidetones, etc? I don't own one; just curious. Thanks & 73 Jay W6CJ

Tnx but the core is in pieces and I don’t have all the pieces. Ordered a different transformer which I will strip off and wire it as it should be. 73 de Bjorn Skickat fr?n min iPad
