In 1965 I was a tech so was restricted to 6m and up. I mostly was on 2m which at that time I was allowed on 145-148 MHz. Virtually all phone (voice) was on this segment at the low end. I had a Johnson 6N2 (5894) and ran a Johnson Ranger-II for PS and modulation (AM). I had a Clegg Interceptor-B which was one of the first VHF SSB receivers so I could tune in 144.064 MHz which was the 2m-SSB frequency in the mid-west. I had a xtal for that freq. so I could talk with the SSB guys by running AM. Later I swapped for a DX-100 to supply plate modulation running two 1625's at 120w audio which should have over modulated the 5894 but the mod transformer was mismatched enough to load down the modulator at 150w RF output. My xtal frequency was stabile enough for the SSB guys.
I "keyed" the radio by throwing a transmit-stby switch on the receiver which controlled the Dow Key coax relay. The relay had auxiliary contacts which keyed the transmitter. Most transmitters of that time had simple mic connectors with no PTT switch contacts. The transmitter keyed either via the CW Key jack or some pins on the octal aux connector (remember those?). Two controls for the final: LOAD was peaked for plate current and TUNE was dipped for plate current (or do I have that backwards?). That got the final about to resonance and max output. I only lost one tube during those years. Back in my Novice years on 40m I tuned CW or SSB by advancing the regen control on my 3-tube "Ocean Hopper" receiver until it went into oscillation. I had my CW Key connected across the speaker to run the receiver like a code practice oscillator. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?
