[Elecraft] Firmware bug??

[Fred Bennett N9TA]

   Hi Gang

I have noticed a peculiarity with my K2 (ser#242). This
radio has the firmware that came with the I/O module. I
did NOT notice this peculiarity with the older firmware.
        The nature of the peculiarity is as follows:

If I start changing bands going UP frequency ....pass 10M
and go thru 160M....when I get to 80M my K2 Xmits 1 (One)
dah.   ??!!??    Yes, it actually TRANSMITS 1 dah !!

            Anybody else got this.....bug??

              73.....de......Fred  N9TA
