My TRX DATV composed of Portsdown 4 v 202104250 and Pluto with an Arduino sequencer to control the power supply
for the antenna preamplifier, the antenna coaxial relay and the PTT of the PA.
Therefore the 8 seconds delay is not useful, can you tell me the line of code necessary to adjust this timining between 500 mS and 2S?

Thank you,

Thanks Dave for your answer - the minimum achievable time is 2 seconds, ok for my application !

I just now noticed this interesting discussion.
Dave could you tell me if to activate a delay in PD4 it is necessary to act on some command or just modify this command line? If you wanted to have a programmable key with different timings in the PD4 menu that would be great. Do you think it's possible?
