Roger G3XBM's (Mainly) Amateur Radio Blog

When I started in amateur radio most people were on AM (amplitude modulation) even on HF.   In recent years there has been a bit of an AM re...

Many AM broadcasters are closing down.  In 10 years' time the MW and LW broadcast bands may be empty of AM stations. This is a great pit...

This was in 2011 and shows me in QSO with the 10mW 2m AM Fredbox. Many years ago I had a cross channel QSO with it handheld. These days it i...

Although there are still a few AM nets on some bands, the mode has mostly been replaced by FM and SSB. This is a pity as in years gone by pe...

When I first came on VHF, most activity was on AM. These days what phone activity exists is SSB or FM with AM quite rare.  In some ways, thi...

When I was first active, AM was the main mode on all bands. On HF this was replaced by SSB and, in very recent times, FT8 has become very po...

Since I released my free G3XBM Project Scrapbook , I have already thought of some things that I have left out!  In the early 1970s, when st...

It seems hard to think this tiny rig was designed and built so long ago (1974?). It was rebuilt a few years ago and still works. It must cou...

With 10m again becoming a good DX band, it does not seem right talking about a simple cross-town natterer for 10m!  Mind you 10m is often a ...

 One of the pleasures of the last solar peak was hearing the USA AM signals just above 29MHz. One of the beauties of 10m is its size. With 1...

It is some while since I was on 2m or 6m AM.  There has been something of a revival in AM, although AM should not be used on busy bands. The...

Although I have not used AM recently, partly as a result of my poor voice, I can see the attraction of the mode. It lends itself to home bre...

10 years ago I had a QSO with my Fredbox transceiver on 2m AM as the photo shows.  I still have the Fredbox, but sadly there is little AM st...

As you will have seen, after a very long break, I took my first tentative steps back into optical communications yesterday.  Before my stro...

This is very late! There are still a few hours left if you want to give HF AM a try. See  https://amqsoparty.wixsite.com/mysite

My  XYL was looking in our loft for some pictures and came across my mobile logbook that I had not seen for over 7 years. I have never manag...

These days many on the air have never used AM (amplitude modulation). Many prefer FM or SSB for chats. Certainly, I get the impression tha...

These days there is very little AM on 2m whereas at one time it was the only mode! The RSGB seems to have an aversion to AM and the 2m AM c...

Southgate News reports on an upcoming AM activity contest towards the end of January. On some bands there is plenty of space for AM. This co...

When I first came on to 2m, AM was the main mode. During the 1970s, FM gradually took over. Also, the Liner-2 got people on the band with SS...
