New Bands

A friend just advised me of a new FCC Petition for Rule Making that
requests the creation of a new amateur band for 8m somewhere between 40
and 41 MHz.

https://ecfsapi.fcc.gov/file/105260090923685/8%20meter%20PRM.pdf

I doubt it gets any traction, but it makes me curious if any mods
(software or hardware) would be practical to allow the K3 or K3s or K4
to cover that range. I suspect the upper low pass band filter would
preclude that possibility.

73,
Dave AB7E

K4 24 hour clock and calendar

The K4 will display time and date; I have seen this on one image. Is there
any chance that in the new design the 24 hour clock and date will hold their
accuracy over prolonged periods? This was not the case for the K3 and
would be an improvement.

SDR, should just be a modification to the firmware.

Re: New Bands

Maybe for RX. For TX, you have to consider spurs, harmonics, filters and
other technicalities. So, it is not trivial.

The K4 should work at 40-41 MHz without modification, though I wouldn't guarantee specs without performance testing.

Yes. In addition they'll automatically update periodically if the radio is connected to a network (Ethernet).
