Experimental V band projects...


Some V band equipment/experiments:

- some notes on my 70 MHz OZ transverter - Finnish amateurs now have access to the 4 meter band - also thoughts on using the FT897D with a transverter (30.08.2009)

- instructions on modifying an 80 MHz band rubber duck antenna to 70 MHz, by Juhani Lehtosaari, OH2MD (in Finnish)

- my version of the OE9PMJ 50 MHz transverter, Po = 20 W PEP, Nf = 1 dB ( outside and inside )

- reworking the OH9VHF and OH9SHF beacons

- a old, but fun photo of the very serious 6 m mobile antenna installation of OM Jan, OH1ZAA ;-)

- several GaAs-FET preamplifiers for troposcatter communication ( example of prototype, ( 79k )

- filters, mixers, power amplifiers

- EER (HELAPS) experimental amplifier

- 144 MHz beacon, 10 W out, not QRV yet
