Just used the free time and nice weather to test if i can reach the QRPP receiver in PY with very small equipment.
Using my old BU500 (@ 450mW) and a 4-turn helical roughly aimed to QO100 gives -13/-11dB SNR... much to strong!
Then i used a old WiFi omnidirectional antenna > -16dB …. still to strong to participate…
Next time i try with a dummyload
BTW: no problem with the TX frequency drift of the BU500 in direct sunlight
