PSK31 versus JT65

I was going to try PSK31 on 10m today, then I read this and decided against it! I shall try 10m JT65 (2W) again.

UPDATE 1648z: No JT65 spots on 10m here today, at least not yet.

First PSK31 QSO from new QTH


E74DO in his shack
After a little while on WSPR I decided to try PSK31 on 20m running 2W to the Par antenna. I replied to a CQ from E74DO and got a 599 report. PSK31 is not a mode I too much like, but it does work when the band is busy and with QRP.

A little later (1646z) I had a nice PSK31 QSO with Svan TF3FIN in Reykavik on 20m.

A PSK31 QSO

Well, the little grandchildren have gone back home to mum and dad so the house is very quiet (and tidy!) again. This afternoon I decided to do a bit of QRP on 20m as a change. First a nice 2-way QRP QSO with Emi IZ4RDX who was running 5W (me 2.5W) and then a PSK31 QSO with Luis EA3UV. Neither contacts were great DX, but fun.  For the PSK31 QSO I decided NOT to use those pre-prepared messages and instead just keyed in what I wanted to say as the QSO went along. It felt like a real QSO, which was nice.

Tomorrow I hope to get back to the optical beacon work, but after 4 days of (lovely) little grandchildren this afternoon I just needed to "chill" as they say.  The plan is to build a beacon TX that will allow a range of subcarriers and also continuous subcarrier transmission as well as CW and QRSS beacon messages. I hope to get out "over the horizon" looking for the signal later in the week. Watch this space - literally if you are nearby, HI.

PSK31 mode

Julian G4ILO mentions his enjoyment of PSK31 on HF on his blog today.  Although I've had a fair few QSOs and some good DX with this mode over the years, I'm not a great fan of it.

Although Julian rightly says it is a very good mode that well complements CW and SSB, and it is certainly true that the PSK31 part of the bands are often busy when CW and SSB signals are absent, to me QSOs feel too formalised with exchanges that follow fairly standard formulae. Too often it feels like a PC talking to a PC. Maybe I should try next time to avoid using these pre-programmed messages and go for a normal free-form keyboard "chat" instead.

It's a while since I've tried PSK31 on HF. Maybe next week when the grandchildren go home I'll give it another go.

The ARRL reports that Varicode, as used in PSK31, has now been officially recognised by the ITU. See http://www.arrl.org/news/amateur-created-varicode-adopted-as-itu-recommendation .

10m PSK31 QSOs

Having found 10m open tonight as a result of some WSPR reports from the Faroe Islands, Italy and Portugal, I went onto 10m PSK31 and had a couple of QSOs with YL3GBF and S56EPX when running about 3W QRP. Solid contacts, but I don't really like PSK31 - the QSOs seem so "artificial" and PC generated. I do try to type as I go though to put some variety into the contact.

DM780 is an excellent package for this mode and many other digital modes.

6m PSK31

Just heard CT1ESJ working an ON station on 6m PSK31. Not thought of using this mode on 6m, but it could be pretty useful for working DX on the band. Certainly the PSK31 area around 50.250 was quite quiet.

Incidentally, I was using Pocket-Digi on my Dell Axim PDA to do the decoding just picking up the signal from the loudspeaker.
