RCA Tx1 Closes When Not Assigned To

Craig Gagner
Craig Gagner Member ✭✭
in SmartSDR for Windows

I observe a repeatable issue whereby when going from 2m which in Tx Band Settings RCA Tx1 is selected to key an external amplifier, to any HF band and transmit, the RCA TX1 relay closes and keys the 2m amplifier. RCA Tx1 is not selected for any band other than 2m. Upon transmitting again, the problem clears until I go back to 2m, transmit and return to an HF band.

Running: Win 11 on a Dell optiplex 7090, 11th gen intel

Flex 6700, SmartSDR v 3.10.10

Q5 2m amplifier keyed via RCA Tx1

Any insight would be appreciated.

    Note also, the same condition can be created on my Flex 6300 as well.

    I saw a bug report from someone with using 2 RCA ports so this might be linked, Mike replied and said it was a known bug in 3.10.10

    You could try reverting to the previous version.

    Would be worth submitting a ticket too,

    TX Band Settings are set per each TX profile. Did you verify the settings you're looking at are the TX profile being used?

    This is related to a bug in SmartSDR v3.10 being tracked as SMART-11727. A fix is going through our Alpha process. Look for the fix in a future release.
