AM operation

These days many on the air have never used AM (amplitude modulation). Many prefer FM or SSB for chats.

Certainly, I get the impression that our national society, the RSGB, is anti-AM. They have continued not to put 144.55 as the AM frequency of choice in 2m bandplans. They continue to have the fatuous remark about AM users being mindful of bandwidth, when well set-up AM often occupies less bandwidth than FM. I also found out that one RSGB official had no idea there was a preferred slot for AM on 10m! I get the impression that they haven't a clue!

AM has its place on less busy bands. It also lends itself to easy homebrewing. To me, it seems a shame that AM is hidden away. It is not the best mode for many reasons, but well modulated AM on 10m is a real joy to hear.

10m transceivers

Looking on the internet, there is a wide selection of 10m (28-29.7MHz) transceivers available. Many can be extended (illegally in the UK) to cover CB frequencies.

As an example, the Alinco DR135 is available for £144.99. I am sure shopping around will show that lower prices are possible. This rig was available (special offer) for less than £100 recently. At one time, single band 10m rigs were illegal in the UK. This is no longer the case and these rigs can be a low cost way of getting on this most interesting band.
