What relays are recommended for pilot copilot ptt isolation on flightline
fl760 transceivers. Thousands of relays are shown on suppliers web sites
making it hard to pick out a suitable one.
Thanks in advance.

For Experimental Aircraft, the Navworx ADS600-EXP is a self-contained
ADS-B in and out for about $1200. The ADS600-B at $1999 is for certified
aircraft and seems very similar to the FreeFlight unit. However the
Navworx units are both in and out and for $100 you can add wifi to
display traffic & weather on a tablet. The $1999 FreeFlight unit is out
only. Their in/out box is $3700.
I went to an ADS-B seminar on Sunday and the presenter said that Mexico
is going to require 1090ES. I haven't been able to verify that, however.
Just another datapoint if you're trying to decide on UAT vs 1090ES.
Something else I hadn't realized--for those thinking they can avoid
airspace where you need ADS-B out--is that you can't fly over the top of
any Class-B (actually the mode C veil) without ADS-B because the veil
extends to 10,000' and ADS-B is required (in most places) above 10,000'.
In my part of the country that's a significant inconvenience.

Search Mouser or Digikey for these relay characteristics:
Non-latching, 12VDC nominal coil voltage (13 or 14 OK), SPDT or DPDT, 1 amp contact
rating, price less than $5.
A panel mounted switch can be used to disable the copilot PTT. A relay is needed
to connect either the pilot or copilot mic. Both mics should not be connected
to the radio at the same time.
