Thanks to everyone for you help.  I have the 4 rebuilt 4 section cap back in and connected properly.  The rig sounds great!   73,   Bill NZ0T

Re: [drakelist] Fw: TR7 Mike Gain

Bill,   Normal mic gain for a TR-7 with most dynamic mics is around 9 to 10 o'clock. The mic level to obtain the ALC led increases with frequency. Pin 3 of the mic connector runs straight to the transmit exciter board, pin 4 goes through a 470k resistor. Pin 4 was for mics with high output I

RE: [drakelist] Fw: TR7 Mike Gain

Bill:   I assume from your post that low mic gain has always been a problem, since you said that you were surprised that the output of the mic did not improve when you switched mics.  Assuming that you have an acceptable impedance match, before you tear into the rig to do any mods or trouble

Re: [drakelist] Fw: TR7 Mike Gain

GM Bill - I believe that the microphone can be wired differently to operated on the TR-7.  However, if my memory serves me correctly, the second mike input is for Low OUTPUT microphones (The manual does not use the term "Lo-Z or Hi-Z  impedance" for the input wiring). The use of the HC-5 should be

RE: [drakelist] Fw: TR7 Mike Gain

Hi Bill,   I had eactly the same problem with my TR7, but I also noticed that the ALC was rather slow in action. I found this on the internet, written by G4ALG:   "Examination of the TR7 ALC indicated an attack time of 10ms and the delay time constant was very long. Only leakage currents and

Re: [drakelist] Fw: TR7 Mike Gain

Hi Bill,   I had a similar problem with my Kenwood TS-520 years ago when I replaced the mic element in my D-104 mike with a Heil. I tried several transformers to get the low impedance element up to the 50 k-ohm input the radio was looking for.   The final solution was to wire it direct without any
