Occasionally we have some annoying QRM on 2 m over here making working to the south quite hard. ๐Ÿ™ Tick, tick, tick. Ticks about a second apart, sometimes just s2, sometimes as loud as s7. It’s driving the transceiver’s AGC … Continue reading

A new 4 m Band Pass Filter

Having changed the 4 m antenna to a single band one there’s no need to use my trusty coax diplexer anymore (one half of it was described here). It served very well eliminating all the interstation interference between 6 & … Continue reading

A transverter interface for the ‘7300
