 You may like this transceiver from India. For the price it is remarkable. It is built around a Raspberry Pi.



Monday plans - no radio?

 As we have to go into Cambridge for some Christmas shopping, I may not go on the radio today.

Museum at Christmas

This weekend, our local museum had a "Santa's Grotto" in the windmill. The children loved it and were told a story (in groups) and were each given a gift. To them it was magical.

In the main museum, there was face painting, mulled wine, minced pies  and much more. We helped with the raffle.

In all, it was a great. happy, occasion for all, especially the children.

The museum and windmill near us is having a Santa’s Grotto weekend. 

We’re helping today.

Sunday plans

 Probably 500mW 10m WSPR and 5W 6m FT8 later.

WSPR?

The impression I am getting is that WSPR is going down in popularity whereas FT8 is going up. I was considering buying a dedicated multi-band WSPR TX and WSPR RX.  I am having second thoughts.

WSPR needs less bandwidth (about 6Hz) than FT8 (about 50Hz) but WSPR is more sensitive by about 10dB. Maybe many cannot make use of this because of local noise. Also FT8 allows 2-way QSOs.

Last evening I tried 40m WSPR  and FT8. On WSPR I spotted nobody, whereas on FT8 I spotted 12 stations in a similar period.
