10m FT8 RX on the cheap

This has definitely been on before, but as we approach sunspot maximum (and beyond) a timely reminder is in order. 

This works remarkably well and can be made very inexpensively, yet will bring in stations across the world most days. It may be built "dead bug" or, if you are really keen, as a simple PCB. As I have said before, it would make a great club project on a PCB.  The circuit is simple, so a single sided PCB should be straightforward. It means the "big rig" is free yet 10m FT8 may be monitored.

Bots? - NOT amateur radio

Already I have had more than 3 times the number of visits to this site than yesterday.  My posts are as boring as ever, so I think this must be bots probing.

Where I come from in South Devon - NOT amateur radio

This is where I lived as a young child. 

Funny how we just took it all for granted. 

It is now the most expensive resort in the UK.  Salcombe.

Cambridge Store - NOT amateur radio

Many overseas visitors are fascinated to see what is on sale in UK shops. This was the fruit section of a Cambridge shop last week.

10m 500mW WSPR TX (Wednesday)

Gear turned on about 0845z.  At 0905z, no spots.

UPDATE 2112z:  Today, 23 unique stations have spotted me. QRT shortly.

8m QRP FT8 (Wednesday)

My gear on 40.680 MHz FT8 (TX 1st, DF about 1950Hz) was turned on about 0845z. Unsurprisingly, no spots at 0856z.

UPDATE  1426z:  I am told by HC02 (1808km) that I appeared briefly in Southern Portugal but this did not appear on PSKreporter.  On RX the only spot is of 9A3TN (1481km).

UPDATE 1750z:  HC02 has spotted me again this evening. His report is now on PSKreporter. Also spotted (just!!) by SR4BBX (1217km) in Poland.

Plans for Wednesday

The impression I am getting is that Es is not as good as yesterday. My plans are 10m WSPR TX with the 500mW beacon and 8m FT8.

Sunspots - Wednesday May 31st 2023

Solar flux is 162 and the SSN 144. A=5 and K=1.

Clematis - NOT amateur radio

 

This picture shows clematis in flower in the garden at the moment. It is past its best now.

10m QRP WSPR (Tuesday)

On 10m with 500mW WSPR TX. So far (at 0848z) already 36 unique spots!

UPDATE 1340z:   56 unique station spots of me today!! Incredible.

UPDATE 2017z:  63 unique station spots. QRT soon.

8m QRP FT8 and WSPR (Tuesday)

After a brief outing on FT8, I have decided to try 8m QRP WSPR all day. HC02 (1808km) has spotted me on FT8 and WSPR.

On WSPR I am using 2W on 40.680 MHz (DF about 1550 Hz).

UPDATE 1444z:  Several WSPR spots for HC02 (1808km) as well as a couple from DC1RDB (884km). No spots on 8m WSPR RX.

UPDATE 2035z:   More WSPR spots by HC02 this evening. QRT soon.

Sunspots - Tuesday May 30th 2023

Solar flux is 154 and the SSN 153. A=4 and K=1. 

What is it? - NOT amateur radio

This plant was in the herbaceous garden at Anglesey Abbey. 

I should know the name but I don't. 

UPDATE 2130z: See below it looks like it is called the King's Spear.

10m QRP WSPR (Monday)

As my 10m antenna is free, I am on 10m WSPR TX with my 500mW beacon. At 1051z, spotted by 4 stations with plenty of Es.

UPDATE 1807z:  19 stations have spotted me today. Lot of Es.

UPDATE 1947z:  22 stations have spotted me today.

QDX-M 630m - not yet!

Following a recent email from Hans it is clear they are concentrating on the 160m version first. The 630m version could be some time, as the toroids on the LPF will need lots of turns! Judging by the results of the higher band versions of the QDX, I have no doubt the 160m and 630m single band versions will be very good.

8m QRP FT8 (Monday)

A few moments ago, I QSYed to 8m FT8 QRP.  My thanks to Hugh HC02 (1808km) who has already spotted me in southern Portugal.

Stations spotting me
today on 8m QRP FT8

UPDATE 1900z: 6 stations have spotted me today so far on 8m FT8.  3 stations in Eire. Quite a good day really. Thank you to all reporters.  2 stations spotted on RX. One was an EA. I hope he was legal.

10m QRP FT8 (Monday)

At the moment (0824z) I am on 10m FT8 with the little QDX transceiver. I have yet to check conditions this morning! So far, just a couple of Europeans spotted, but nobody has spotted me yet.

UPDATE 09427z:  25 EU stations have already spotted my QRP 10m FT8 today, so I may QSY to 8m QRP FT8 and 10m WSPR with my 500mW WSPR beacon. On RX, stations as far as Western Australia have been copied on 10m FT8.

Sunspots - Monday May 29th 2023

Solar flux is 151 and the SSN 119. A=11 and K=1.

QDX-M 630m

When this is available, I quite fancy one. My transverter produces about 10-12W of WSPR on this band.  It would be good to try the QDX-M next winter, on 630m, if available. I think the output would be about 5W on the QDX-M.

15m QRP FT8 with the tiny QDX (Sunday)

At the moment I am trying 15m FT8 with the tiny QDX transceiver. Conditions are better than 10m, but still pathetic compared with yesterday.

UPDATE 1513z:  I have gone RX only after a brief period on TX. 

Stations spotted on 15m
FT8 RX today to 1518z

UPDATE 1618z:  326 stations spotted on 15m FT8 RX.

UPDATE 1923z:  720 stations spotted.

UPDATE 2132z:  877 stations spotted. Now QRT. The QDX RX works really well.
