[KX3] CW +SSB with external transverter problem

Scenario:

KX3 with external transverter and amplifier on 144MHz. (Transverter RX/TCswitched from KX3 keyline out).
Wish to use CW+SSB feature where hitting the key in SSB mode transmits CW. This is an option in the CW WGHT menu, selected by tapping 1.
CW in SSB is something that is used on VHF DX where fading sometimes means having to quickly switch to CW from SSB during a QSO.

Result:

Tapping the key in SSB mode now keys the PTT line to transverter at the keying rate, irrespective of DLY setting or whether VOX or PTT is selected.

So it cannot be be used as the relay switching in the transverter and amplifier is not capable of switching at the CW keying rate.

Questions:

Is this how this feature was meant to work?

Could it be altered so that the CW VOX delay is honoured when using CW in SSB mode? This would then allow the feature to be useful with external PTT (Keyline) driven transverters.

Many thanks,

73

Re: [KX3] CW +SSB with external transverter problem

One further note, I am using an external keyer, not the KX3 internal keyer. I just tried the internal keyer and it does work as I would expect.

Re: [KX3] CW +SSB with external transverter problem

You need to set the VOX Delay while in the CW mode, to a long enough time to keep the transverter from dropping out. You'll likely want to reset that if you go back to CW operation without the transverter.

Also, it was a relatively recent firmware version that fixed the problem. Be sure you have the latest version.

Re: [KX3] CW +SSB with external transverter problem

Hi Jim, thanks for replying.

I am running the latest firmware and I do have VOX delay set in CW mode. However the 'bug' appears to only affect keying with external keyer, and works fine with the internal KX3 keyer.

Slightly annoying as I prefer to use my old CMOS superkeyer to anything else because I am familiar with it and like its timing.

Re: [KX3] CW +SSB with external transverter problem

Aha, think I have found the problem, it was related to the setting in CW WGHT - VOX AUTO OFF - if this is set ( that is not VOX NOR) then when powers up the set behaves as I described, and needs to switched to CW and VOX put on again. I think I have it working reliably now with my external keyer in SSB +CW now. It is still a bit funky even with the internal keyer chosen after a start up with VOX AUTO OFF enabled, you have to switch to CW put VOX ON then back to SSB mode to get CW in SSB to work with VOX.

It might have been better if the VOX was off for the paddles not to key the PTT at all in SSB + CW as it is rather disconcerting and not good for relays in the transverter for it to have the keyline keyed at the CW speed.
