Welcome

Welcome to my amateur radio and electronics Blog. My name is Carl and I live between Northwood and Rickmansworth on the Greater London / Hertfordshire border. This new blog was started 26th December 2020 although I am in the process of transferring some of the more interesting posts from my old Blogspot pages. My main radio interests are:

* VHF to SHF DXing and contesting
* HF Dxing, digital modes and contesting (particularly RTTY contesting)
* Equipment and antenna construction, including homebrew and kits

My personal contest callsign is G2K. When contesting with ‘The Rats’ you may hear me using either our club call G3RAT or our club contest call G2D, we also have the club call M0HRF but that is used somewhat less now that we have been issued G3RAT.

Some of the equipment at M0ICR:

Icom 7600 V2
Acom 1010

Often I will use a seperate full-wave loop antenna on receive (at the home QTH) which is used to receive on an SDR Play 2 using SDR Console 3.0 software.

Trusty old workhorse for 2m DXing – the IC751 with MuTek front end
Another oldie but goldie! The hybrid Kenwood TS530SP

Despite the fancy Icoms etc and potential to operate up to 400W on HF when the situation is appropriate I still very much enjoy operating low power low cost radio. I am a big fan of Hans Summers and his QRP Labs enterprise. You can find Hans’ website here and his QRP Labs shop here. I particularly enjoy the QCX Mini range of CW QRP transceivers owning one for each of 20m and 40m. See Hans’ QCX Mini Youtube video here. Here is one of my QCX Minis connected to a QRP Labs GPS module:
