Re: No receive on AM side works great on SSB
Hello cqdx, wow, where do I start??? That radio is about 30 years old, and a lot of changes have taken place on the circuit board componants. Not to mention that the Royce line of radios were not of the best quality even when they were new. Probably you have a solder joint problem or a cap or resistor has changed value. Really not worth the time to troubleshoot and repair. As a tech, I would much rather spend the time on a good quality radio to repair, and not something that will be back. Just my opinion, as a 10 year tech. Mechanic

go to you tube and type in your radio make and model and watch the review on that radio there is a freq adjustment pod for ssb adjustment. they might tell you if not take it to a radio tech and he should be able to alighn it. there is more than one pod for ssb transmitt and receive.
What radio?? Does it have single side band(SSB)? If not, then don't use SSB.
AM - amplitude modulation SSB - single side band.
If you have SSB, there would be a switch on it to transmit in SSB. If not, it is AM only.
Second, Has this radio been worked on to be able to run on an amp? If not, you will blow the amp.
A CB radio transmits dead keys with 4 watts of power, and transmits with 4 watts of audio.
a 4 watt dead key is too much for a linear amp. You will smoke the transistors. Also, 4 watts of audio is not enough to drive it properly. You won't get full power.
The dead key needs to be around 2 to 2 -1/2 watts,or what ever makes the linear dead key half its peak wattage., and the modulation (audio) turned up all the way.
It doesn't sound like you know too much about CB radio's. Not a big deal, you can learn. For right now you may want to take it to a cb shop and tell them you want a peak and tune, and set up to run a linear.
You can find CB shops usually at truck stops. Some area's they are other places. Check the internet for local shops.
If you are using the radio on a boat, then no, the grounding does not matter that much. However, an SSB transceiver would be hassle to install on a boat because of the amount of power they use to transmit. If the transmission is bad, try using the radio's internal tuner instead of the separate tuner. This may help improve the quality of transmit, however, some radios have a tough time clarifying incoming and outgoing signals and create a garbled sound when it receives a signal or when it transmits. If that doesn't work, then you can try grounding. But if you want a radio that doesn't require all this nonsense tning, you might want to think about investing in a Yaesu. They are pricey, but are one of the best HAM radios.
