/P operation

We leave Devon in the morning and I did not turn my amateur radio gear on once! This is a good sign as we spent far more time than I expected enjoying the walks and the scenery. No doubt I shall be  WSPRing again when I get home.  At least I know that I can still enjoy the things I used to do in my home county.

OK, I am more reluctant to use my (poor) voice on HF SSB. This is much harder than it was. Instead, I was happy to walk and look instead.

Bang good portables

There is some confusion over these radios. Although some are limited in the number of channels and some may come pre-programmed, for example, for the  European licence free 446MHz band, several models (such as the ones shown yesterday) say they can be re-programmed in the 400-470MHz range. If so, they would make very low cost 70cms portables.

 On the Bang good website there are even lower cost units for the USA market.

Portable and fixed mobile DXing

One of the things I'm looking forward to when I overcome my stroke is being able to enjoy portable and fixed mobile operation once again.

The image here is of operation last year from the edge of Dartmoor in Devon.  Several stations were worked in the USA with just a base loaded whip and 2W SSB from the FT817.

I am likely to be denied a driving licence for 12 months, so I have a long wait! My wife drives the car but does not like driving too far.

A novel QRP power source

FreeCharge 12V is a small, portable generator, similar to that used in portable hand-cranked torches. The output is regulated to give 12-14.2V DC although the product datasheet does not state the available current. I suspect it is in the low milliamps as its main use appears to be to power/charge mobile phones in an emergency.

This could make a novel power source for low power QRP transceivers as no batteries would be required, just a few seconds or minutes of cranking.  Figures given are 360 turns (approx. 3 min wind) gives 9-11 minutes of mobile phone talk time and a 60 second wind gives 2-4 minutes of talk time. Price is £19.99 and it is available from Freeplay or via Amazon UK.

The sales blurb says:
"The Freecharge 12V provides emergency power to a mobile phone, PDA, iPod, GPS receiver, or any other electronic device for which you have (or can get) a cigarette-lighter adapter. Wind its hand crank to generate electricity and put power straight into your device. Never be unable to use your mobile phone, or other important device, just because its battery has run down."
