Hello, I am Robert M0NVQ, a licensed amateur radio operator and my QTH is Oldham, Greater Manchester. M0NVQ is my callsign.

This is my amateur radio blog, which means that primarily, amateur radio topics will be covered. My amateur radio blog posts provide details of forthcoming amateur radio rallies, events on the air, contests, amateur radio suppliers, allocated frequencies, and other amateur radio websites.

How I became interested in Amateur Radio

I first became interested in amateur radio in 1972 when I joined Sutton Coldfield Radio Society Unfortunately, ‘A’ levels followed by university, a rewarding career, and busy family life kept me occupied. However, in 2012, I decided to retire and planned to rekindle my interest in amateur radio. I took my examinations and worked my way up to a full licence:

  • Foundation in November 2012 – M6RCL,
  • Intermediate in February 2013 – 2E0FIT,
  • Advanced in May 2013 – M0NVQ.

There are quite a few repeaters near me and I also have my own MMDVM hotspot. So it is easy for me to access both D-Star and DMR. I have enjoyed working Saudi-OSCAR 50 satellite using my handheld homebrew yagi, which was good fun.

I have had some success operating from my home QTH using an inverted halfwave dipole trimmed for the 40-meter band (and also the 15-meter band on three halfwaves). However, background noise has proven problematic. Operating with the same inverted V from my telescopic fibreglass pole at locations in the countryside was more successful in my experience, even though the weight of the coaxial cable did bend the pole.

One consideration, whether setting up an antenna at home or in the country, is speed of deployment. To overcome the problems of centre-fed antennas with heavy coaxial leads, I tried random length non-resonant end-fed wire antennas but I found setting up earthing gave inconsistent results and to be time-consuming. However, I found deploying resonant end-fed halfwave wire antennas to be very easy, whether from an upstairs bedroom window at home or up poles in the countryside. None of my QRP transceivers has a built-in antenna matching unit. Therefore, I have employed a 64:1 tunable transformer configuration based on a design by M0UKD – essentially a zeppelin antenna. This has proven usable on 80, 40, 20, 15, and 10-meter bands.
