I hope this is the right place to post this thread. If not, I apologize and please move to appropriate area mods.
Here's my quandary and I'm hoping to get some suggestions.
My Yaesu FT-857D runs hot even on standby mode on the 13.8vdc that my PSU supplies. I read that all my radio needs is 10vdc to put out full power(something with the exciter stage). So I lowered the output voltage on my PSU to 12vdc(which solved the heat problem). Now the problem is that voltage drops to below 10vdc(to around 9.2) when I transmit on full power and audio starts to break up.
Here's what I thought up but I don't know if it's feasible. I up the output on my PSU to 13.8 and I put some kind of voltage regulator on my power line to get only 10 or 11 volts.
My question is, will this work? And how do I do it? Thanks in advance folks.
