Thanks to WB6BYU and WD8OTT for the advice. I think i will need to adjust the carrier for ssb. Yes every time I'm testing i switch from whatever mode I'm in cw,lsb,usb. Your assumption is correct.
As far as feedback in the audio circuit, I realized today that the speaker wire coming from the power supply was wrapped around the power cable, Going from the power supply to the radio. Since the matching power supply also has a build in speaker.
I quickly decided to take WD8OTT advice and swapping out the matching power supply for an Alinco power supply. I went for easy first!
What i discovered quickly was that the humming sound i thought was coming from the power supply, was not coming from the power supply but rather the speaker in the power supply. This is when i decided to untangle the speaker wire from the power cord and i installed a ferrite choke with about 5 turns.
The improvement was immediately noticeable with the hum, although not gone. I decided to put a ferrite choke to the power cable with about 3 turns.
This basically eliminated any hum that i was picking up through stray RF. After doing a few quick test i have noticed that when i key up the mic in LSB the carrier is now only about 10 watts, Where before it was 100 watts keying down the mic without speaking. Seems to have improved but problem still exist.
Although it still continues to have a 100 w carrier in USB when i key the mic on 20 and 40 meters without speaking. 10 and 15 meters seem to act as they should. Power output on 80 meters is low. I assume this radio needs a good alignment.
I will take your advice Dale and have a look at the SSb/CW switch.
I will also take a look at adding some more ferrite chokes in different positions with different amounts of turns, to see if that corrects any issues.
I wish i had more technical knowledge to tackle this problem. Regardless I appreciate the help that i have received over the past few days.
Nice to see the Ham community as i remember it.
