80m WSPR unique RX spots using 15m E-W earth-electrode "antenna" |

80m WSPR with 15m earth-electrode "antenna"
Since lunchtime, I have been using the 15m E-W earth-electrode "antenna" on 80m. On RX it has netted me 17 unique spots with best DX OH8GKP in Finland at 1994km. With 2W on TX best DX so far is OZ7IT at 853km. The antenna current with 2W RF from the FT817 is lower than on 474.2kHz. This is the status at 1925z.
27 spots on 474.2kHz QRPP TX with15m earth-electrodes
After about 10 days, my total number of spots received has risen to 27 now with best DX report still from F1JBB in SW France. On RX I have copied EA, I and LA as best DX and loads and loads of stations. ERP 5-10-mW. Performance is at least as good as on the 20m spaced electrodes at the old QTH.
Time now to concentrate on another band with the earth-electrodes? 160m is the next obvious choice.

OFCOM - are they ALL automatoms?
Having now contacted OFCOM very many times in the last month I am getting heartily fed-up with the auto-response email system advising me to wait 5 days for a reply. So far, it is more like 5 WEEKS and I have still to hear from a single human being as opposed to that damn machine! You may recall my inquiries related to sub-8.3kHz operation and operating with very low power around 73kHz and both queries should require straightforward quick answers.
They really must be understaffed, or is it just that unlicenced stuff (i.e. no income stuff) automatically goes to the bottom of the piles? Personally, I am less than impressed.
At current rate of progress I am getting inclined to TX on ANY frequency as I doubt ANYONE at OFCOM is actually bothered unless anyone happened to complain. And I am one who likes to keep to the law!
Based on OFCOM's total lack of interest I assume sub-8.3kHz can be used freely in the UK. Surely they would have screamed," NO, NO WAY!", long ago if they had a serious issue? I do wish they would reply unambiguously, and soon.

Stroke progress
After several days when, frankly, I felt I was going backwards, this morning I awoke free from sickness and nausea and feeling quite a bit better. So far, I have chosen to take no pills at all. I still feel a lot better, still wobbly on my feet but 50% of my old normal self rather than 45%. For the first time in many weeks I feel a full recovery will come given time.
UPDATE 1730z: Downhill after lunch. Drinking coffee (especially) and tea seem to be more problematic than they should be , even with thickener added. I felt worse again this afternoon, and after SUCH a promising start today.

26 uniques on 474.2kHz
25 uniques on 474.2kHz WSPR with15m baseline E-W earth-electrode antenna and 5-10mW ERP |
I'll leave things running overnight tonight. The earth-electrode antenna does not show pronounced directionality, which is a bit puzzling as it throws into doubt the "loop in the ground" theory. I would have expected reports from N-S to have been much weaker than E-W directions.
The ~15m baseline earth-electrode antenna has now exceeded ALL my expectations for it with DX reception at least as good as with the 20m baseline earth-electrode antenna at the old QTH.

Back on 472kHz
I have decided to go back onto 472kHz WSPR TX (and RX) with the 15m baseline earth-electrode antenna. Already I am getting spots from the usual UK local and semi-local (101km) stations. I shall leave the system running through the night in the hope of increasing the total number of unique spots of my signals to greater than 22. On RX I think I need a preamp with the earth-electrode antenna as signals are weaker than with the PAR antenna "in the air".
2nd FT817 and a Z817 auto-tuner
After a lot of consideration, this week I purchased a second FT817 (this time an FT817ND) as well as the LDG Z817 auto-tuner. One thing to bear in mind is the Z817 is no longer supplied with a 0.5m long coaxial RF patch lead. It comes with the CAT cable only.
My FT817ND has been widebanded so it covers 5MHz and I went on that band for the first time today and was spotted on WSPR in Holland with 1W to a totally non-resonant antenna matched with the Z817.
I must say from a QRP base station point of view the Z817 is a neater, and much cheaper, ATU solution. It matches the Par 10/20/40 end-fed on most bands and seems to do as good a job as the Elecraft T1, which I need to repair as it is intermittent.
The second FT817 means I can WSPR on one band and operate on another band at the same time. As I have just bought the OLD version, you can be sure now that Yaesu will showcase a NEW version of the FT817 next month! Martin Lynch and Sons were very easy to deal with and thoroughly helpful suppliers. I can recommend them.
No stateside DX on 10m today but just exchanged spots with CX2ABP at 11127km on 10m with the new kit.

22 unique spots on 474.2kHz with 15m spaced earth electrodes
After one more night, the total number of UNIQUE stations spotting my QRP ERP WSPR signals has reached 22 with reports last evening from PA0WMR (351km). I am now going to try the 15m spaced earth-electrodes on other bands.
Given more time I'd be assured of LOTS more spots especially from UK and Irish stations.

RSGB's Bennett Prize
This morning I received a total surprise in the form of a letter from Graham Coomber G0NBI, RSGB General Manager, to tell me they have awarded me the Bennett Prize, G8PF, to "recognise any significant contribution which furthers the art of radio communications" for my article last year in RadCom on 472kHz earth-electrode antennas. Sadly, my health will prevent me from picking up the award at the RSGB's AGM in Manchester next month. I was quite amazed and very humbled.

2nd FT817 and a Z817 tuner
Today I placed an order with Martin Lynch for the above. I was able to negotiate a decent deal both with MLS and with W+S, but decided on the former. Delivery should be this week. This should allow me to WSPR on one band and operate with other modes on different bands including 5MHz. My original FT817 has served me well and the FT817ND should serve me for years to come.
I have separately ordered a 250Hz CW filter for the new rig.
