6m WSPR - a disaster!

For the last few days I have been TXing and RXing on 6m WSPR with 2W and the V2000 vertical but apart from G4IKZ 18km away I have been copied by absolutely no-one and I have copied no-one either.

There were a couple of other G's on but too far away to copy and no luck from the few continentals active. My hopes of GDX or even wintertime Es were thwarted.

I have now returned to 630m RX and am already seeing LOTS of good European DX.

472kHz TX

Yesterday I wound a loading coil on a 110mm drainpipe for the 472kHz band which should allow me to transmit on the band using my homebrew transverter. The only thing stopping me is fatigue: I get SO tired doing the simplest of things because of my recent illness. With luck, I shall try this later this week.

6m WSPR

Since last night I have been WSPRing again on 6m using the V2000 vertical and 2W.  Apart from good strong reports from G4IKZ at 18km nothing has been reported, including no GDX. I was hopeful that the odd European might have been copied, but no luck so far.  G4IKZ gets me very strongly and reports weaker sidebands sometimes +/-100Hz. I am not sure if this is a TX or RX problem. It is only noticeable on very strong signals.

Building skills - still poor

As a result of my stroke, my building skills are still poor. Today I wound a loading coil for 472kHz on a 110mm diameter former and, frankly, it was very hard work and at the end of it I was exhausted.  Gradually my strength and stamina are returning, but there is some considerable way to go. I think, for now, I should avoid much experimentation that needs much/any building work.

G4VXE sked on 2m JT65B tonight

At 2000z I have a sked on 2m JT65B with G4VXE in Oxfordshire (IO91). Tim is running 25W to a V2000 vertical and me 2W to a V2000 vertical.  I hope we make the sked successfully especially hoping I get copied OK.

UPDATE  2040z: Although I could clearly see G4VXE (with 25-30W) sending JT65B when using Spectran I go no decodes from Tim, which cannot be right. I suspect finger trouble with my software (WSJT9). In the other direction my 2W was only copied as the occasional sync pulse and no decodes. G4VXE would have been workable on CW so I must be doing something wrong at my end with JT65B.

472kHz spots

My 472kHz WSPR reception continues and I now have 27 unique stations in the log. The latest stations, include HB9 which is also a new country, and the other station a G.

I have also wound  a loading coil and hope to TX on the band soon assuming I can match the antenna.

More 10m WSPR

Late this afternoon I was on 10m WSPR again with 2W and the Par 10/20/40 antenna. Yet again, the band was wide open to the USA and Canada with plenty of spots in both directions. Really, at present, 10m WSPR is too easy as DX is always there when I look.

UPDATE 1840z:  2.5 hrs after dark the 10m band was still wide open to the USA but then the transatlantic path suddenly died out.

Stroke

Walking at Anglesey Abbey today

My recovery from my stroke continues to frustrate me: although walking and swallow continue to improve, I have a feeling of sickness and nausea nearly all the time I am awake. Also I continue to be very clumsy when it comes to building.  Putting screws back in the FT817 case after fitting the TCXO-9 was a nightmare. I dread to think how I'd get on with any substantial building project.  For now, most of my experiments are with the kit and antennas already in place.

Any day now I am expecting the DVLA to tell me I cannot drive for 12 months. Luckily I applied for, and got, a blue disabled badge which means we can park nearer to the entrances at National Trust  places and supermarkets when shopping.

Transatlantic reception on 474.2kHz WSPR last night - 5888km

It had to happen and did (eventually) last night. WG2XJM (EN91wn) at 5888km was copied 3 times during the night on MF just using the FT817 (no preamp) and the untuned Par 10/20/40 antenna. Signal levels were not great, but as to be expected, at around -30dB S/N. 

So far this season, this set-up has now copied 25 unique stations in 8 countries and 2 continents on 474.2kHz WSPR.

Unique MF WSPR spots over last 2 weeks

TCXO-9 fitted

This afternoon I fitted the (loaned) TCXO-9 into my FT817. A sign of how my stroke is making me clumsy still, getting the screws back in to the FT817 cover was really hard work, when it should have been easy. TCXO calibration seems spot on. Tonight I am trying to decode G3WKW on 2m WSPR, so far without success even though Bob's signals are clearly visible on the WSPR screen.

UPDATE 2045z:  a solid decode of G3WKW (134km) at -24dB S/N no doubt aided by planes over N.London. At least with a warmed up rig fitted with a TCXO-9 my calibration on 2m is spot-on now.

Someone, asked me to measure RX current before/after fitting TCXO-9. Sorry,but I forgot and will not now do this because of my stroke and issues with fitting screws to the FT817 case - at present some things are just too hard for me.
