SQ Lab Transverter 1296MHz sequence timings

Some tests taken today. NOTE: tests were made with jumper 4 ON (rf vox activated)! NOTE2: RF OUT signal is taken from FWD pin of swr connector.

1.7ms from PTT in via coax to PTT out in 3.5mm jack socket
26ms from PTTout to RF signal at output
450ms from end of PTT signal at coax input to end of PTTout signal at 3.5mm jack

GPS wewnątrz radia Kenwood TH-D7 | GPS inside Kenwood TH-D7


Użyłem modułu GPS oznaczonego jako: GPS-GMM-R1. Prawie na pewno każdy moduł GPS który startuje w trybie 9600 bodów NMEA się nada.

Cold Start TTF: 1.5-2 minutes. Hot Start: 20 seconds.
