[drakelist] R7

[Evert Bakker (PA2KW)]

Hello all,   I’m looking for a digital copy of the R7 service manual and TR7 user manual. Who can help me?   The R7 I own seems to work well except the audio which is not the Drake quality. It sounds sharp (much more high tones then the TR7) and “ticks”. It’s tiring to listen to! I suspect the AGC circuitry but may be someone can give me a hint on this. I also hear a high tone (several Kc’s) coming from the power supply part. As you can see, I need the manual.   Thanks in advance   Evert Bakker (PA2KW)   Drake TR7, #6426 Drake R7, #2838 Elecraft K2, #4836 Ten-Tec Paragon
