I am considering to build a simple 1 Watt amplifier.
The Power module is quite expensive. It costs 60 dollar + shipment. I may buy it later.In the mean time I could build a simple 1 Watt amplifier. That should be enough for local qso's. Maybe some DX as well when the conditions are right. Later, at sunspot maximum, I could buy the module. Replacing the 1 watt Amp with the module should be easy. I hope the module is still in stock then.
I have a couple of 2N3866 transistors available. Two of them in push pull configuration should do the trick. I may get a bit more out of them. Two watts may be possible. However the inter modulation may be to high. I will have to try as I don't know how to calculate it.
