10m sideband

Before my 2013 stroke, I had every intention for designing and making a very simple rig for 10m sideband. Several ideas were already on the table, but I never had time to do this. Since my stroke I have found it almost impossible to design and make things.

Times have moved on and a synthesised VFO is probably the way to go nowadays. Also, for a single band like 10m, a phasing SSB rig would probably be fine, even if the LSB suppression was not perfect.

In my view, 10m will be a great DX band for many years. I hope somebody else (not me) will take my ideas and design a simple, low cost 10m sideband rig. I can imagine a nice, simple and easily reproduced sideband rig for £20-40 being possible. Imagine, working the world on a simple sideband rig you made.

10m Simple Sideband

Yes, you read correctly - simple sideband, not single sideband.

For some time, I have had in my mind a very simple 10m rig. Sadly, my stroke got in the way, so this has not progressed. Such a rig would be ideal for Es and, certainly here in the UK, most of Europe should be workable with a simple antenna. At some point, I'd like to complete this. Maybe someone else already has.

A few years ago, the whole world would have been workable. Sadly with declining conditions, this is far less likely now on 10m. May, June and July are the best months for Es (sporadic-E) in the northern hemisphere. Of course, there is nothing stopping you work local SSB stations at any time.

Fivehead QRP SSB transceiver kit

This afternoon Ted G4NUA came around to test the receiver section of his Fivehead 20m SSB transceiver kit from Walford kits in Somerset. I was surprised how small the transceiver was. We checked the RX with a signal generator and re-did the alignment. We then tried it on an external antenna and it was about the same sensitivity as the FT817 and was copying plenty of stations on 20m SSB. Ted has still to finish the TX part. When done it should put out about 1.5W pep.

DSB mod for the Heathkit HW8

When looking around for ideas for DSB rigs I found a page which shows how to modify the HW8 for DSB operation by adding a balanced modulator and audio stages.  KL7R reports that he worked New Zealand using the modified HW8 on sideband.
