Most of my QRP operation has been on the MF and HF bands, with some experimentation on 136 kHz when I was operating as GW4ALG.  My current equipment includes:
- a homemade transceiver on 80 m;
- an Icom R71E as my main station receiver;
- an Icom IC756PRO3, mainly used as an item of test equipment;
- a multi-band VXO transmitter, for 80/60/40/30/20 m
- a Rev 2 QCX transceiver for 80 m

The measurement of transmitter output power is accomplished using a Welz SP220 power meter, and a homemade audio bandpass filter to the PA0LQ design (40 Hz bandwidth) is used to improve the selectivity, as required.
