Yesterday I built a front panel for my Mythbuster II 20 meter SSB transceiver.
I used 1/8 inch plywood available from Amazon.
I cut holes for the main tuning knob and dial, for the AF gain control, for the mic plug and for a 6 figure PLJ PIC frequency counter. This gives me 100 Hz read capability, but I can hit the lower button on the counter to get 10 Hz reolution. This may help when the other guy complains bitterly that I am 40 Hz off frequency. The counter added noise to the receiver, but I was able to knock this down completely with a resistor and a cap on the power line to the counter.
I put copper tape on the inside of the panel.
I added a reverse polarity protection circuit. I now sleep more soundly.
I increased the size of the heat sink on my RD06 final. This decrease the danger of blowing up this device.
I added a jack for the connector that will switch the outboard .1 kW linear from R to T.
Video above. Comments welcome.
My vote is that you and Dean KK4DAS build an RF Power Amp with the balanced design he is considering using a pair of genuine 50W 12V RF Power Transistors...
