Is there a way to not key our amp when the antenna is being tuned

Dennis Daniel KM6DF

I need a way to not key my amp when I use the tune button. Any ideas

Stand by? If your amp has STBY,, or DDUTIL

Dennis we need more info then you provided like what type of Amp do you use DDutil etc. The easy answer put your Amp in standby. Ian

Most any amp that I am aware of has a Standby switch.

I should have added more info. to start i have a flex 6500 and running a Amertron als-1306 through a HF-Auto. What would be nice is when you push the tune button it does not triger the RCA TX1 this way the amp will not TX at high SWR when you are tuning. I have DDutil setup so when I change bans it will defalt to standby but you have to manually turn it back to operate eash time it would be nice if it would do it from the tune botton.

thanks

Dennis.. I assume the HF Auto you mention is an automatic tuner external to the ALS1306?  If so, it should have a key line in and out (most do) that will also open the key line to the amp while the Tuner is actually tuning.    Many of the better power wattmeters such as the LP100 and or the Array Solutions wattmeters have a feature that will prevent the amp from keying when a manually preset SWR value is reached.

Later HF-Auto tuners no longer have the keying line.  While Dennis' request is an interesting one, I plan to just switch the amp to "Standby" when tuning.  There are enough software keyed items (like XIT) that don't "take" when first selected that I would not want to trust the SSDR software with this one, for sure!

Dennis I use DDutil and just turn Amp to standby with that program when I hit the Tune button. There doesn't seem to be a Macro for it to automatically do this for you. Ian

I have an Elecraft KPA500 amp and KAT500 auto-tuner which supposedly uses the 6300's Tx relay to inhibit the amp when tuning (key line method). The signal path is 6300 Tx relay out -> KAT500 PTT relay in-> KAT500 PTT relay out -> KPA500 PA key. However it doesn't work right and often causes a fault on the KAT500 tuner. The only way to make the KAT500 tune reliably is put the amp in standby, tune per the normal procedure, then put the amp back on line.

The way i do it is with a footswicth from Heil... i have the FS2, this one KEY the amp just beofre the radio... so when i press TUNE, i can tune my AT-1000 pro 2 tuner with 15 watt ( preset ) and when ready, i just press the pedal, i can then do the TUNE and LOAD of the amérotron, i then release the pedal and tune button and ready to transmit safe and full power

Put a toggle switch in the PTT keying line from the Flex to the amp.  Disable PTT connection to the amp while tuning.

Update on my question. I have setup DDUtil and it controls the ALS-1306 so everytime i change the band and retune my SkyLoop it will put the amp into standby and I can tune the HF-ATO as normal however you must put it back into operate from DDUtil. I was hoping to make it more automatic when you use the tune button in the SmartSRD software. It would seem to be somthing simple to do though the SmartSDR software.

That behavior, sounds like you have BOBC enabled in DDUtil which will force the PTT relay to standby on a band change. Uncheck that and it will likely remain in Operate on band changes if that's the behavior your after.
