[Elecraft] FCC Proposes to Permit Amateur Access to 2200 and 630 Meters

[Jim Miller]

I think many of the 630m crowd are doing fine with 100w and 5% antennas

I think patience is in order for the 630 m allocation.  I'll bet "BND END" will go away and the K3's will transmit once the FCC has formally acted and it has been published in the Fed Reg.  Filters in the TX chain might require some mods of course.

Depending on what the ultimate Part 97 rules say about this allocation regarding antenna size, height, power limits, and required EIRP computations, 100 W from a KPA3 into a compliant antenna could be QRPpp in EIRP. :-)

2200 m is another issue.  Sensitivity on my K3 with the new synthesizer is just as Wayne said it would be ... low.  There's also a LOT of noise down there, or at least there is where I live.  I noticed that years ago when we were experimenting with LORAN-C aircraft receivers for locating busses and I had one in my truck [a receiver, not a bus] for a month or two.

At 100 KHz, railroad tracks have some strange effects also.
