Before my 2013 stroke, I was working on a simple rig for 10m. At the time I was thinking of a dead simple DSB transceiver, but these days a ...

Now, I am very happy to be told I am wrong, but I think DSB rigs can be received on other DSB receivers, but it is much more tricky than re...

10m is coming back to life.  At any point in the solar cycle it can be good for Es contacts (in the Es seasons especially) with low power a...

In the next 12 months, 10m is returning as a great DX band. At any part of the solar cycle it can be good for Es contacts in April- August i...

Practical Wireless has a piece on a tiny, low cost, DSB rig kit that is ideal for digital modes like FT8. The article is written by Marti...

My health has not been good for over 5 years, so work on this project stopped sadly. The ideas were good ones and I am sure there is milea...

Stephen G7BFY sent me a link to a video on YouTube of the Japanese 3 transistor DSB transceiver featured in this blog some years ago. It is...

From Steven, G7VFY comes news of a very simple 10m DSB transmitter from the blog of KA7OEI . This is an experimental very low power transmit...

http://aa7ee.wordpress.com/2013/10/19/the-vk3ye-micro-40-dsb-transceiver/ has a beautiful description of the building of this little transc...

Regular readers of this blog will recall that about a year ago I started breadboarding a simple DSB speech transceiver for 10m. Having had g...

As I cannot access my "lab" currently (kitchen refit materials are everywhere!) I am restricted to operating from my shack, so thi...

My favourite HF band is 28MHz and I often put my FT817 on and run WSPR in the background whilst getting on with other things in the shack...

G3XIZ has been having a lot of success on 40m WSPR recently using a 100mW DSB transmitter to generate a WSPR signal. All that is needed is a...

Thanks for the suggested names for my 10m DSB project. The one that wins is the Tenbox , which is the logical name following on from my earl...

Today I continued breadboarding the TX strip of the 10m DSB transceiver changing the single balanced mixer to a broadband design and adding/...

Today I spent a little time on the transmit strip of my 10m DSB transceiver project . I started with the single balanced mixer using a T50-6...

A long overdue project of mine is a QRP 10m simple sideband (DSB) transceiver. Having got the 4m transverter working (circuit to follow) I&...

The weather's a bit warmer (0 deg C) so I'm going to start on the local oscillator section of my DSB transceiver today. Will almost ...
