SuperYagi Airband Antenna.

My latest purchase was a new antenna dedicated to the civilian airband 108-136 MHz.

The…

Scanner Greats.. Yupiteru MVT-7000 brought back to life !

In the early 1990s ,The Yupiteru MVT-7000 multiband scanner had an almost cult following amongst Aircraft Enthusiasts and Marine Band Listeners, especially with hobbyists based in the Netherlands.

Revolutionary in its day, it comprised of some software (freeware I think) on a floppy disk and an demodulator dongle distributed and sold by Lowe Electronics, Matlock….

This is an unusual antenna in my collection, the PA0RDT active mini whip. Normally I would be sceptical about the performance of such a small device for HF use but I read a few favourable reviews on the internet and decided to order one for using with my Tecsun PL-600 ssb radio and I thought it…
