Thanks for the time an effort to help me out! It sounds like this is what I need now to get this old radio doing what I want it to do! I appreciate your time and effort. If I am happy with the results, I am going to probably do a PLL mod to add some lower channels and maybe look at upgrading the mic inside the handset to something with some better punch (maybe an amplified D104 type electeret upgrade or similar).Thank you for posting that SAMS. i tried searching for it but the search function on this forum is not so great.
so the diode you are looking for is D-506.
the AMC is VR8.
you'll want to peak the transmit before you do the mod so you will end up with the desired deadkey level without detuning any coils.
peak L901 for max deadkey. peak L903, and L905 for max PEP modulated wattage.
Don't touch F901.
