Hi Dave,

I agree with what you say to do, log it as RY.

My reasoning is based on the fact that I upload my logs to LOTW and use that for Awards purposes. So a mode designation is needed that will [1] be acceptable to Cabrillo and [2] be acceptable to LOTW, and which will [3] likely "work" what your QSO partner has uploaded to LOTW to give you a confirmed QSO in LOTW.

For digital modes and LOTW, the ARRL states at:
http://www.arrl.org/files/file/LoTW%20Instructions/TQSL%202_0%202013/Secodary%20operations/Digital%20Modes.pdf

"LoTW will match a QSO as long as the calls, time (+/-30 minutes), date, band and mode are the same. For digital modes all digital sub mode (PSK31, JT65, JT9, MT63,OLIVIA, etc.) will qualify as DATA. (The same applies for voice modes. All voicemodes qualify as PHONE). That is to say that if you log a QSO as PSK31 and the other operator logs the same QSO as RTTY then LoTW will match the QSO, assuming all other parameters match, and each operator will be credited with DATA"

And the chance that your QSO partner will log a digital QSO as some digital mode, I believe, is significantly greater than the chance that he will log it as "PHONE" or a phone mode.

So RY it is :)

Ken,

PSK is not a legitimate Cabrillo mode. According to the published Cabrillo 3.0 specification on the WWROF site, these are the only legitimate Cabrillo modes:

CW
PH
FM
RY

Based on this, even W5ZN's suggestion to show it as SSB (which was almost certainly the mode your transceiver was set for) doesn't comply.

As some have suggested, the mode is not a scoring parameter in the ARRL VHF contest, so perhaps it doesn't matter. In the end, it all boils down to what the ARRL contest robot and the logchecker will accept.

If it were me, I would do like K7CW suggested and change it to RY. Then there can be no argument that it is legitimate Cabrillo data representing a digital mode QSO.

We made some JT65 EME QSOs in the June VHF contest.  Is there a correct
mode to use, or is mode irrelevant?  We currently have it marked as PSK.

Many thanks, Kenny K2KW - C6ATA in the contest.
