I am talking to a local on 38 LSB. I am cutting out after about 2-3 seconds of

USB. Then I went and put the radio in the car, and the problem went away. The
local said it's my power supply not having enough juice. But it's 12 amp
constant, 14 amp surge. It's a PyramidPS-14KX. Again, I am running barefoot with
a HR-2510. Is it the power supply? Should I add more caps for filtering?

Can anyone help?

Try finding a small (inexpensive) 13.8V Car battery, and hooking it in
parallel (+ to + and - to -) with your power supply.. The battery will
pick up the slack the power supply can't provide, and the supply will
charge the battery when you're not talking.. Neat solution...

One caveat, though.. once the battery is at full charge, you'll need to
either turn off the power supply, or turn something on (a radio, etc) to
provide SOME load to the power supply so the batter doesn't get overcharged.

I run all my HAM base station gear like this...

I am still trying to narrow it down. This might be an intermittent problem. I
was talking SSB during the day, and this didn't occur. Could it be an RF
feedback problem? I just installed an 8 foot ground rod, and will run the wire
tonight. Would this dissipate some of the RF?
