[Elecraft] disabled controls during TX

[HA3AUI]

Thanks for all the answers, it's reassuring to know that at least, the 
problem is already known.
For those, who write that the K3 cannot check the front panel due to TX 
overhead issues, I don't think there is more processing power needed 
during TX, instead, I think it's RX that is more process intensive seen 
the number of functions implemented during RX.
On the newer ICOMs, you can change almost everything during TX, once 
back in HA, I will check the 1000MPV for this aspect, but as well as I 
remember, I had never had this problem using that rig during the many 
contests.
