QRP Ham Radio Project - Perfboard Transmitter

QRP "Homebrewed" QRP Transmitter using perfboard (temporary circuit board) construction technique for prototype two stage 160 meter solid state CW transmitter using 1843 kHz crystal controlled 2N222 NPN oscillator and IRF510 power MOSFET transistor power amplifier pi output filter: approximate power output 1.2Watts.

Woudln't that actually be perf board and not breadboard.?

OH2FFY GREG - Thanks - yes perfboard. I also have a solderless breadboard (protoboard, solder-less plugboard or solderless prototyping board)it does not require soldering but has capacitance between the metal strips in the board. I found for this prototype circuit the unclad perfboard was the simplest. I soldered these connections, but have used wire wrap technique with #30 enamel insulated wire on previous perfboard projects. Thanks for your comment Greg and 73 DE NG9D LYNN

Who says ham radio is expensive ?

I'd like to see the schematic for this please.

Hi Lynn ..yeah , exactly right mate.

You would have to watch out with that extra capcitance on VFO's as well.

I prefer to make up my own PCB's from scratch if my circuit is above 90% workable.

Of course real 'design as you go' prototypes require a bit more flexibility in cosntruction techniques.

I try to do most of my protyping on paper first if I can.

Looking forward to seeing more of your vid'z----
