Since the circuit uses components that are QRP level, I decided to go with a QRPish dummyload. A long time ago I located some 2 watt 200 Ohm resistors. I used them to make a dummy load that would handle 8 watts. The circuit board once upon a time dangled from the dummyload like some sort of absurd dangily earring. It just makes more sense to put the dummy load on the circuitboard. This is the result shortly before hookup:
|Ready To Test!|
|Ready to Use!|
I plan on using this to test my designed Colpitts oscillator, but until then, the glowbug I have now will have to do. The first time I measured the voltage things seemed a little low.
|This seems low.|
That measures out to 0.9216 watts. ((Vp-p * sqrt(2)/4)^2 / 50) And then I got to thinking. I remembered that the last time I checked the RF output on this lil' tube radio was without my NoGAwatt attached! I pretty much just used just the dummy load dangling off the back of the radio. That was one of the reasons why I moved my dummyload onto the circuit board.
I took the NoGAWatt out of the equation and this is what I got:
|Much Better Now!|
ah, maybe later. Right now is time for operating!
|One last internal shot.|
Eventually, I hope to make this something that is publish worthy. We'll see how that works out.
