8m experiment (Sunday)

As I am busy setting up with 10m FT8 on the IC-705, it is unlikely I shall be testing on 8m FT8 today. Maybe at teatime?

It would appear that by Es my QRP 8m FT8 signal can be widely copied across Europe. Unlike many of the better equipped stations on 8m, I have not been copied outside Europe.

UPDATE 1245z: On 8m FT8 QRP TX on 40.680.

FT8 with the IC-705

A while ago I tried FT8 with the IC-705 using a USB cable from the PC. As the noise level was high, I stuck with the FT817ND and SignaLink instead. As I have now got a good screened and choked  USB cable, I shall try again later. 

UPDATE 0858z: Well it works on TX with a spot by G0FWX (160km), and I think it works on RX, although nobody spotted yet. At the moment it gives 5W without the ALC coming on. Assuming all is fine, I shall probably download WSJT-Z, which goes back onto CQ TX after a QSO. With WSJT-X it goes to RX after a QSO. 

UPDATE 1005z:  Working on both RX and TX. Initially I was seeing none of my RX spots on PSKreporter, but there are lots now as well as lots of TX spots. Best DX on TX is a spot of me by ZS6KVZ (9120km). No QSOs yet. I wonder how much better FT8 is than SSB? Having worked ZL with 10W SSB some years ago, I am pretty sure I can get DXCC on 10m FT8 if I tried. Not sure I really want to try. 10m FT8 at 5W seems too easy!

UPDATE 1802z: 
Spotted by 36 stations on 10m FT8 TX with 5W. Furthermost is DP0GVN (13687km) in Antarctica. Other reports from S.America, Middle East and China. 10m FT8 certainly works with the IC-705.

This is my grandson in 2010 (I think) "helping" me in the back of the garage. He is now 14 years old. 

Final Dayton report

For those who went to Dayton, Ohio, USA, I think it is fair to say that reactions were mixed. Many enjoyed the huge fleamarket, but many were disappointed with the new "toys" being launched. 

There were few real eye openers and Kenwood was not there at all. I think they are already leaving the amateur radio market. In my view others will follow as there is no longer a mass market with juicy profits.

Sunspots - Sunday May 29th 2022

 Solar flux is 102 and the SSN 34 (low compared with recent days). A=24 and K=3.

Disappointing HF conditions here

Certainly, up to now, 10m and 8m have been very disappointing here with no spots at all on TX or RX. I think conditions are disturbed, but I am seeing no evidence here of F2 or Es propagation.

8m FT8

At about 0745z, my QRP 8m FT8 TX was turned on on 40.680 MHz USB dial. No spots on TX or RX.

UPDATE 1317z:  No spots on TX or RX 8m FT8 today.

UPDATE 1611z: Yet again, 8m FT8 spots were exchanged with EI9KP (649km). With a received report of -10dB S/N I can only conclude that this was either aircraft or Es. I have lost count of how many times he has spotted me on 8m FT8. He is by far my most regular reporter. He was also copied here (again).

10m QRP WSPR TX

Yet again, I am on 10m WSPR TX with my 500mW W5OLF beacon. No spots yet. What I thought was today was yesterday.
