I am a great supporter of the GQRP club. Their quarterly magazine SPRAT represents the very best in Amateur Radio. If you are interested in QRP then please join the GQRP Club. It is excellent.

There is now a new, up to date version of the DVD with all back copies of the excellent SPRAT magazine.  If I had to stop all subscriptions and magazines then the GQRP club (and SPRAT every quarter) would be the only one I’d keep  – it is that good.

Hi

Tony & I have been working away and we have produced the latest version of the Sprat-on-DVD. This includes all Sprats right up to the one that has just been sent to members (number 160).

It is now available to members at £5 plus £1.20 postage. I will have them at the Galashiels rally and at Rishworth of course. The local guys who represent us at some of the other rallies will also have some shortly.

As we have known that this issue has been on the way for a while, as a concession, we will let anyone who bought the current DVD (1 to 148) after 1st August this year, have a copy of the new DVD for the special price of £2.50 including postage. To get this deal, you have to tell me when you bought the old DVD – if at a rally, which rally it was, and send me the CD case paper label together with the £2.50 in stamps. I do not want the actual DVD, just an assurance that you will destroy it when you receive the new one.

I should add that this is for members only of course, and applies just to UK members! Overseas members who think they also qualify should contact me direct and we may be able to work out a deal for them also.

Overseas prices are on the club website – http://gqrp.com/sales.htm

The new DVD is available to non-members at £12 plus the appropriate postage.

Thanks

This is a beta release of WSPR (version 4.0). It has worked fine for me.

This is the version I currently use on all bands. Unfortunately, it does not have the real-time waterfall. You see the action only after a 2 minute TX period and not during the transmission as was the case for WSPRX.

The interface looks very similar to WSPR V2.2.

Please let me, and others, know if there are more recent releases by adding a comment and link.

The three VE stations active on 630m CW are looking forward to working you tomorrow (Halloween) evening via the crossband mode during the 630m Activity Night.







In the east, watch for VO1NA. On the west side, watch for VE7BDQ and VE7SL. Here are the transmitting frequencies, times and HF calling frequencies:

• VO1NA - Joe, in Torbay, Newfoundland. Joe will transmit on 477.7 kHz starting at 2130Z Oct 31 and will continue until 0130Z Nov 1. He will listen for callers on 3562 kHz and 7062 kHz.

•  VE7BDQ - John, in Delta, B.C. John will transmit on 474.0 kHz starting at 0100Z and will continue until 1000Z on Nov 1. He will listen for callers on 3536 kHz.

• VE7SL - Steve, on Mayne Island, B.C. I will transmit on 473.0 kHz starting at 0200Z and will continue until 0600Z on Nov 1. I will listen for callers on 3566 kHz and 7066 kHz.

630m propagation conditions have been very good this past week and barring any sudden auroral events, should continue. Unless you are within a few hundred miles of these stations, don't expect signals to be 'loud'. Even when running several hundred watts, antenna's that fit into backyards are not very efficient at radiating all of it! However, from what I have observed, propagation on 630m is very forgiving and has much in common with 160m. Distant signals can sometimes be surprisingly easy to copy when the sun is not up to its tricks!

I have no idea how many stations will be participating on HF but please do not give up should your first few calls not be answered. If conditions appear to be really good, operating hours will probably be extended. Unfortunately Saturday night will probably be out since it is the Sweepstakes CW weekend and will pretty much plug the HF bands, wiping out the calling frequencies.

Don't forget to watch for the Part 5 Experimental stations (WG2's and WD2's) who will be beaconing and working each other on 630m directly. I'm sure they would appreciate your 'heard' reports as well.

Good luck and see you tomorrow.

If all goes according to plan, they plan a soft launch of initial production run in a couple weeks, with full scale mass production following shortly thereafter.







For now though you can download the manual at the link below:

By now, you probably realise that I just love WSPR. With quite simple equipment it is possible to be decoded across the planet consistently with real QRP power levels.   I am always on the look-out for new ideas, although until my health improves I am not in a position to build too much myself. See http://www.knology.net/~gmarcus/WSPR/wspr_v4.pdf for an example of a complete 30m WSPR transceiver.

This is NOT a new circuit  – it has been around for some years – and it still needs a PC for the WSPR software. Some TX-only WSPR beacons use microprocessors to generate the WSPR TX messages, thereby freeing up the PC and consuming little power overall. Some sync to GPS to avoid timing issues too.
