NB6M Miniboots

AMQRP describes the miniboots of NB6M with IRF510. The schemantic describes IFR510 (it should be correct with IRF510). This is very simple RF Amplifier for QRP rigs.
This linear amplifier gets 10-14 Watts with 3/4 to 2 Watt drive. The IRF510 is sold by Radio Shack and the number is 276-2072. The specification of IRF510 can be get by the web page. It is Vds=100V, Id=5.6A and Pd=43 Watts.

I've made the miniboots for my qrp rigs and got 5 watts for 1w qrp rigs. You may increase the power with IRF510 D-S voltage. I've checked it with 24V and got 10 watts.

Need a bullet proof 10 Meter CW transmitter for beacon. Prefer to run at about 2-10 watts out if possible 24/7. Frequency 28.300 mHz. Will pay for someone to build and deliver. Must basically idle at the 10 Watt level so as to last 24/7 operation. Contact Rick, KF4MS, rickainsworth@gmail.com
