happy to report that an upgrade to 3.3.9 (and the associated full
database reset) resolved the issue with the open collector
outputs. The band selection on my homebrew amplifier's LPF is
now working properly in both RX and TX modes.<br>
<br>
Thanks again to all who responded.<br>

<div>I have used the Open Collectors to control relays to
select the LPF on my external PA right from the start, and
it has worked as expected right through all the versions of
PSDR over the past several years.</div>

<div>The following may be stating the obvious, but sometimes

<div>Note that the pins on J6 go towards ground when
activated, so these need to be connected to the ground side
of your relays, there needs to be +12 V on the other pin of
all your relays for this function to operate. Also, the
“External Control” (button on v3.3.9) must be selected to
activate or set up the OC feature.</div>
