AM Transmitter Kits Empty AM Transmitter Kits

Post by Guest on Sun Dec 23, 2012 10:07 am

I'm sure many members here have built and designed their own AM transmitters or made one from an old unrestorable AA5.

I'm wondering if anyone has used one of these kits;

It doesn't mention the power output and I see the modulation is screen grid. Looks like a nice kit.

This is all the kit says about transmitting power;

If you want more power, then up the HT voltage, 36 to 45 volts (4 or 5 PP3 batteries) will provide a strong signal for around the house.

I still prefer SSTRAN.

I assembled it, put in better electrolytic capacitors and installed it in my uninsulated detached garage. It's been going strong 24/7 for well over 6 years now Smile
