QM5 Yagi for 2 meters band - The QM5 antenna is a simple 5 elements Yagi with 1.88 m boom length for the lower 144 MHz SSB/MGM band, I used it mainly for Sporadic-E and MS contacts. It exhibits a forward gain of 9.17 dBd; i.e. 11.3 dB forward gain over the isotropic radiator, while the F/R is about 11.5 dB. Elements

QM7 7 elements 144 MHz Yagi-Uda Antenna - The QM7 antenna is a simple 7 elements Yagi with 3.70 m boom length for the lower 144 MHz SSB/MGM band, used it mainly for Sporadic-E and MS contacts. It exhibits a forward gain of 11.35 dBd; i.e. 13.5 dB forward gain over the isotropic radiator, while the F/R is about 12.5 dB

Stacked 7-Element-2m-Yagis - These yagis and groups were designed with YO7.23 from K6STI and checked with EZNEC from W7EL. With a gain of 14/17/20dBd they have a good relation between gain and mechanical problems.

WA4DSY 56KB RF Modem - This is a prototype of the WA4DSY 56KB RF modem. It is intended for use on amateur packet radio networks. The modem generates RF in the 28 to 30 mhz range and requires and linear transverter to convert the signal to a UHF or microwave ham band

A low power 3.5MHz ARDF transmitter - This low power transmitter is developed for ARDF exercising purposes but of course can be used as super QRP transmitter either. With 1 or 2 meter wire as antenna and a ARDF receiver with ferrite-rod antenna the range is about 100m but with better antennas and a 'real' receiver the range is probably much larger.
