Some VHF Tinkering

On the way home from work on Friday, my attention was brought to my mobile APRS setup, which was showing received callsigns from Germany, Netherlands, Belgium and France. Once home I decided to connect up my KAM KPC-9612+ TNC to an old Kenwood PMR and see what I heard. The antenna is just a loft-mounted Diamond […]

Icom IC-7610 RigCAT XML for Fldigi

During DXpedition to the Island of Islay 2018 with the Camb-Hams, it became apparent that using the IC7610 with Fldigi would be useful. A quick search on the internet showed there to be no IC7610.xml file and no model listed in RigCtl. I decided to hack the IC7600 and IC7300 files to create an IC7610 […]

BA5SBA RTL-SDR Kit

A few weeks ago I ordered a BA5SBA RTL-SDR direct sampling kit from BangGood (link here). When it arrived, I decided to put it together. The kit includes everything needed, an RTL-SDR dongle, case, PCB, enamelled wire and so on. I worked from numerous build instructions (here, here, here and here), following the clearest description of each […]

Nagoya NA-771 Antenna X-Ray

Some weeks ago I brought a Nagoya NA-771 antenna from BangGood. I had previously brought such an antenna before, but noticed this was slightly different in design. Upon use, I noticed this antenna was inferior in terms of both transmitting and receiving performance. When compared to the standard flexible whip antenna supplied with the radio […]

160m WSPR

Over the night of 14-15 April 2017, I decided to run WSPR on the 160 metre doublet at GB0SNB. The transceiver was the Icom IC7100 with a transmit power of 3W. The map of both transmitted and received signals was reasonably interesting: We received 18 unique spots and was spotted by 47 unique stations. Our […]

1kW 144MHz Amp Pallet

Those of you who have been following this project evolve will have seen how I soldered the transistor to the heat-spreader and before that how I machined the heat-spreader & heat-sink after their initial use. Most recently, I have been building the new W6PQL pallet, based on the revision 4d schematic, found here. This pallet offered […]
