[Elecraft] 2 different 144MHz transveters and CAT selection

[w4sc]

Henk,

I looked at this issue and it is a K3/K3S issue.

I was able to setup 2 transverters (XV1 and XV2) on the same band and switch between them when the band change was initiated from the K3 front panel.

When a frequency is sent via RS232 connection, it appears the K3 wants to determine what band it should be on determined from the frequency.  It begins this check without checking to determine if it does have a correct band already selected.  The checking would appear to start with XV1, finding a “match” then switching to that band (XV1), even when XV2 is selected previously, and the frequency is correct.  This is from  my observation, and may be over simplified.

The only solution I have determined is to access the config menu and turn XV1 OFF.  XV2 will then be the first match for the frequency sent, and thus selected.

I verified this issue using the RFSpace SDR-IQ and SpectraVue s/w, and in the K3 both  XV1 and XV2 set for the 1296 band.
