Frequency Limits by license?

Can the KX3 be programmed so the operator be limited by their license privileges?

Re: Frequency Limits by license?

Because it can be programmed to adhere to several country limitations, I
am certain that is *possible*, but that is not a user programmable
feature, and requires a substantial effort on the part of the Elecraft
staff to provide such limits. So I doubt that it would be done for US
customers.

Part of the requirements for obtaining a license in the US is to know
and abide by the limitations of our license class - you just have to
look at the frequency display - it has been that way on all HF
transceivers that I have encountered and many of those were 'wide open'
and would transmit on any frequency that they were tuned to. It is the
responsibility of the operator to know where he is transmitting. I
think it is an unwise thing to try to depend on the transceiver to tell
you that you are out of your band limits, but then I am an 'old timer'
with 'old thinking' - I would not want my transceiver to try to tell me
I am out of my band limits - I reserve that for my own judgement.

They also change from time to time.

It always was your responsibility to make sure you were transmitting
within the ham band. I know it was my responsibility because I still
have the "Pink Slip" taped to the back of one of my log pages from that
era, more than one stage of my HB transmitter had decided to become an
oscillator. Sadly, there was no firmware in my HB open-chassis 807
transmitter to warn me. :-)

Re: Frequency Limits by license?

It wouldn't be a good idea to depend on the transceiver. If you are
operating USB, for example, you have to keep the (suppressed) carrier
frequency several kHz below the top of the band so your sideband will be
inside it; same for LSB and the bottom of the band. Even in CW there is
a consideration of bandwidth, although the K3 series rigs have very
narrow CW signals. But it would not be prudent to operate exactly on the
band edge.

Re: Frequency Limits by license?

My concerns are a bit different. While I like having the radio
keep me honest, and as an extra class licensee, I'm in good
shape with the current radio firmware, I worry about
emergencies. The FCC allows us to work out of band during
emergencies, but I can't move to a public agency frequency in an
emergency because there is no override in the firmware.

Now anytime you work out of band, you should expect to have to
justify it to the FCC. One hopes that they will be gentler than
loss of license and a $10,000 fine if you have a good reason for
your operation. If you have a good reason, it should also play
will in the court of public opinion. YMMV
