Are we also using the Flex ALC(16) jack to the Amp ALC jack as well?
I'm Seeing different responses on this matter posted.
Anything else I should be aware of?
I'm going to leave the drive at 50 watts just in case I neglect to change it.
In the Radio setup screen I have transmit settings all enabled with "0" timing on all. In Interlocks - TX Req both RCA & ACC disabled. Both Hardware ALC and Show TX in Waterfall are disabled.
Does this require any changes.
The ALS-600 T/R relay enable time is typically 15 milliseconds. Many transceivers permit setting a time delay between their relay-control output, and the actual full-power RF output. If your transceiver has this capability, set this delay to 20 milliseconds to ensure you don’t transmit before the amplifier relay fully energizes (which can result in the loss of part of the first Morse character).
Note: Transceivers should only be used in semi break-in mode when controlling the ALS-600 T/R relay. QSK (full break-in) operation is available with the Ameritron QSK-5 external solid-state T/R switch.
I'm not a QSK-guy so putting in the 20ms delay doesn't impact me at all and I decided it was fine insurance.
BTW, I continue work on my Arduino-based interface between the Flex and ALS-600 for automatic band switching. The hardware is 90% the same as the Ameritron ARI-500. Instead of a Pic microcontroller, I'm using an Arduino Due and Enzo's fine libraries. I am adding an LCD display to show the TX freq and band selected.
Of course, I am inhibiting keying on an ALS-600 fault but I also inhibit keying if the Flex TX power exceeds a preset value(both low duty cycle mode and high duty cycle mode values). This way you can run full power barefoot but not over drive the amp if you forget to dial back the power.
The software has been tested in a breadboard. The hardware build is nearing completion, leaving actual connection to the ALS-600 and testing. More to come.
