The Spatz (German Spatz) is a small monoband CW transceiver kit designed by DK1HE and distributed in kit form by the German QRP Project. Despite the small size and relative simplicity of the kit, the Spatz is a quite advanced transceiver featuring goodies like DDS with RIT/XIT, 8 pole Cohn Filter with 400Hz bandwith, AGC with high dynamic range, heavy duty PA, built-in keyer and full QSK. The kit can be bought with DDS ready built and tested and is available for the 80, 40, 30, 20 and 17 meter bands.
The WM-2 from Oak Hills Research is a cool QRP wattmeter kit, which can measure forward and reflected power in three ranges: 100mW, 1W and 10W. With an accuracy of 5% of the full scale it should be possible to measure powers down to 5mW using this instrument. The WM-2 has a big, easy to read scale and can operate either from a built-in 9V battery or an external DC source.
Ok, I don’t know what happened… For some reason, no sparrow progress since Oct last year. Anyway, I am back, and working on the Sparrow again!
Today I’ll start building the Sparrow. The kit arrived by mail some 7 days after I ordered and payed for it, so I am quite satisfied with my shopping at QRP Shop so far.
