Because of my poor voice (as a result of my cerebellum brain bleed) I tend to use
digital techniques, like WSPR and JT65, but I still enjoy AM. Like
many, I've worked transatlantic AMers on 29-29.1MHz with real QRP and
simple antennas using AM. It makes a great change from SSB.
One could be forgiven for
thinking AM is a dirty word at the RSGB. In UK Band Plans published in the February 2015 edition of RadCom, AM
gets no mention on 28MHz and 50MHz and gets a (begrudging) comment as a
footnote only in the 144MHz Band Plan when other modes get "centres of
activity" mentions. AM is alive and well
in the 29-29.1MHz sub-band. AM on the 144MHz (2m) band here in the UK can be found on
and around 144.550MHz. There has been AM on 29-29.1MHz for years and
years and years - in fact almost as long as I've been active on the air. Yes, this is in the all-mode section, but why not say this
is the 28MHz (10m) AM sub-band? Also, why are 144MHz AM users asked to
"consider adjacent channel activity"? AM should easily fit in 6kHz!!
Yet again, AM is being treated as a dirty and outdated mode. Here in the UK, ex-PMR AM rigs ripe for use on VHF can be picked up
for virtually nothing and there is certainly room for AM on all bands from
28MHz upwards. AM has its enthusiasts on other bands too, but yet again
the RSGB seems keen to kill off this mode. Why I wonder?
Allegedly, a RadCom article on digital TV in the 146-147MHz band was pulled last month at the last minute because "someone at the RSGB" thought it would not fit in the new band! Sometimes one wonders. Maybe the day when I only get SPRAT is closer than I thought? Thankfully, there are many good articles in RadCom.
