With 10m in such good shape, perhaps it is time to remind readers of my very simple receiver for 10m FT8. It works remarkably well and could...

With 10m so good at the moment, may I remind you of my very simple and low cost 10m FT8 RX? 10FT8R is a DSB receiver than works remarkably w...

If you just want to monitor 10m FT8, may I recommend my 10FT8R receiver? This is easy to build, even "dead bug" style, yet works r...

This has been on before, so this is just a timely reminder.  10m FT8 is becoming very popular and this receiver allows 10m FT8 reception wit...

Now seems a good time to remind people of my very simple 10m FT8 receiver, the 10FT8R. Even buying all parts new, I doubt it would cost more...

At the moment 10m is in great shape with plenty of DX via F2 most days. We are also approaching the Es season in the northern hemisphere. My...

We are a few weeks away from the main Es season in the northern hemisphere. F2 propagation on 10m is very good again. Often there is a need ...

  With sunspots again good, 10m is again coming into its own. It is quite easy to copy stations on every continent in daylight now on 10m. M...

These days, 10m is again in great shape. A very simple, but effective, FT8 receiver that does not tie up the main rig is my 10FT8R that appe...

This design is over a year old. It is very simple, but works well. It allows monitoring of 10m FT8 without tying up the main rig. You will n...

In the Northern Hemisphere we are entering the Es season with DX up to about 1500km on most days. The season usually lasts most of the summe...

Once again 10m is good. On FT8 RX most days, most continents can be received on simple low wire antennas.  When 10m is like this, it is quit...

10m is again a great DX band.  Back in the summer, the RSGB printed an article of mine on a very simple and low cost  RX for 10m FT8 called ...

 At about 0845z, my 10FT8R was turned on on 10m FT8 RX. No spots yet after 5 minutes. UPDATE 1100z:  7 stations spotted, with furthermost I...

This weekend, I want to try my simple 10m FT8 RX with 14.037MHz crystals.  As a benchmark, I want to try first with the original design, the...

This DSB 10m FT8 RX was in a recent RadCom and is on the g3xbm.co.uk website. It's a very simple circuit but works well and frees up th...

All being well, my simple, low cost, RX for 10m FT8 should appear in RSGB RadCom in August. This is not certain. My thanks go to Jay W5OLF ...

In the last day 433 stations were spotted on RX including South America and the Caribbean using the 4 transistor direct conversion RX with t...

It is now 0820z. I have been on 10m FT8 RX with the tiny indoor loop and the homemade 10FT8R direct conversion RX for about 5 minutes. So fa...

It is now 0855z. I have been on 10m FT8 RX for about 30 minutes and have spotted 11 stations so far using the 4 transistor RX and indoor loo...
