On receive, there's a DC path to ground going through K3, K1, L1,2,3,4 and T3 On transmit, with the band select relays as shown for 30m, there's a path through KT1, L13,12,11 and T11. Hi five! On Thu, Jan 25, 2018 at 12:33 pm, Arvo KD9HLC wrote:
I can follow a trace from P2 to ground through an inductor, so at DC, like your DMM would be using to check that, I'd say yes. |
