I'm trying to restore / install & eventually operate the GRC series (GRC-3, -5 & -7) systems in my M-42.
So what happens when I fire up my RT-66, RT-67 & RT-68? Do the heavens open and the FCC gods of vengeance and retribution descend to blast me from the face of the planet with their lighting bolts of righteous regulatory fury? Do the birds fall from the sky? Am I cast into outer darkness?
What happens?
Absolutely nothing like that. The only thing to do is to politely check that you have clear swath of 30KC or so, right? 6M is usually not crowded, right? I keep out of the sections that are on the band plan for DX or weak signal, etc.
Someone might complain to you about the signal being wide. More wideness, more narrowband-using complainers. The nice thing aboiut a narrowband complainer is their audio is so quiet in the discriminator you might not hear it only detect the carrier.
I run this stuff at times and never had an issue with the FCC but I did have another ham tune to the middle of my passband and complain that I was overmodulated. I said no, it is a 30KC bandwidth on a military radio. That did not solve the complaint though as the guy was even more indignant and got mad, didn't want to discuss it, and was ignorant of the occasional use of old military stuff.
I guess we can reduce the deviation while transmitting but that does not fix the ensuing receiver problem.
I have a special radio license now that has solved all of these nagging problems. I'm not sure if it expires but it has no date and is apparently available to anyone.
6M AM is popular again. Those sets would be prime for an external modulator but the FM IF is not so good for AM at all, tried it. A solid state IF and detector might do.
