fix(elecraft): read the TX meters when the RADIO says it is transmitting

Browse Source 
The transmit meters were read on k.tx, which records only that OpsLog
keyed the radio. An operator using the front-panel PTT, a footswitch or
the mic button therefore had a panel that believed the rig was receiving
— and since the power and SWR bars are read only while transmitting,
they were never read at all. IF carries the radio's own transmit bit;
that is what decides now.

The meter probe logs RAW answers rather than parsed numbers, and asks a
wider set (SM, SMH, BG, SW, PO, TQ). A command answering in a shape we
did not expect is the interesting case, and parsing hid it behind the
same dash as a command the radio refused — which is what still stands
between us and a working SWR reading on a K3.
