WSPR - WSPRlite

Today we had a meeting in our local amateur radio club ESSLINGEN P02.The topic for this meeting was WSPR.

Bernd DK9BH was the organizer of this meeting. He has ordered about 10 WSPRlites from SOTABEAMS.

I had the chance, to do same basic measurements on one of the WSPRlite units.

Audio CW-Filter NM0S/4SQRP

Last year I've build the cheap Frog Sounds QRP Transceiver. This transceiver has a pretty basic audio section - a simple LM386 audio amplifier with some LC/RC filtering.

WSPR - Drift problems & new synthesizer board

I've build the original QRP-labs U3S from stock. Means the supplied crystal on the PLL-based synthesiser-board.

This configuration is basically working up to 20m with a lot amount of drift, but you will get many decodes on wsprnet.org. On 6m you can also get spots - once a day :-/
