2995dx modulation on a scope

JasonD239 said:
Let me rephrase the question. Is this the correct method people are currently using the NPC mod these radios. Im looking to deadkey about 5 to 30 watts with full swing pep and good average

UPDATE
I put 250 ohms in series with a 1n4001 and ran it parallel with r292 radio is now providing good average swing and a very good adjustable dead key range.

I also removed the two resistors on pin 1 and 2 on the audio IC added the cp-1 compressor on the audio IC.

Thank you for this useful thread

JasonD: What version of the board is your radio? Is it the ept695015c? Or do you know the approx mfg date?

    Does anyone know if you can replace the 2290 in a galaxy dx 93t twin turbine with a 2sc2879 red dot? If so, what would have to be tuned?

    hello
  • @ ShadowDelaware:
    Hambones the entire amp section would have to be retuned, and the rf transformers re wrapped.
