There is a real gap in my knowledge as I have never once tried an SDR based receiver or transceiver. SDR dongles are very low cost, so I really have no excuse.
On the Southgate site I read news of a new SDR 5W transceiver.

Hi Roger,
Yes you are missing out on the fun :-)
Get one of these RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio (Dongle Only) at under $20 USD from the China store.

You may also need one of these if you are near a high power FM broadcast station.

Here's a quick overview

It will be the best £15 you have spent.
If you find that it isn't, I'll give you your money back in exchange for the dongle :-)

Save you money! The uBitx will be more fun for hell of a lot less!
Hi Steve,
The uBitx is a really great project and ideal if you want a single band Tranceiver (in it's current form).
I suggested the RTL-SDR V3 as an introduction to SDR's because of the types of experimentation that Roger seems to enjoy.
The V3 provides a reasonable level of RX performance from (almost) DC to >1.8GHz.
So it can be used on the LF/MF/HF/VHF/UHF and microwave bands (10GHz with a cheap Octogon PLL LNB) and with some fairly simple modifications to a transceiver used as a tracking panadaptor.
In the workshop it can be used as a poor man's spectrum analyser with up to 2MHz span. Add a cheap noise source and a directional coupler and you have the equivalent of a tracking generator and network analyser. Handy for checking filters or antennas.
Not bad for £15 GBP and my money back guarantee :-)
Just sayin..........
