[600MRG] New band, XSH expiration

[Edward R Cole]

Fritz and all:

That sounds like a reasonable approach.  I have been largely absent 
in transmitting for awhile but intentions are still 
good.  Ground-plane is "rolled up" for summer right now but by end of 
September it should be unfurled and ready for operating thru this 
coming winter.  I still have no transmitting equipment for <490 KHz 
so it may be the last opportunity to run my K3 + NDB 100w Tx on 495.

One thing we lack in the existing license is authorization to use 
JT65 and variants.  I could pursue an independent experimental 
license asking for this, or continue with WD2XSH/45.  Of course the 
perfect solution would be authorization of ham radio on 630m.  I do 
hope that will be at 5w ERP vs 1w.  currently, I am capable or 4.15w ERP.

Regarding 472-479 KHz operation I will just have to make time to 
design and build a transverter.  Elecraft has updated the firmware on 
the K3 to allow transverter operating with 10-MHz IF, so a 
transverter using a high-stability OCXO on 10-MHz and the K3 running 
10.472-10.479 MHz is very doable.  I believe 7-MHz was also added for 
transverter IF on the K3.

I have implemented firmware improvements on my KX3 such that 
receiving seems acceptable below 500-KHz.  Direct comparison between 
my SDR-IQ (which tunes to 500-Hz) and the KX3 seem equivalent.  KX3 
cannot transmit on 630m.

So this may be the last year for the ARRL Experimental License and 
use of 495-510 KHz.  May it be a good one!

PS: Rudy your Seaside 600m presentation went well at our hamfest, 
yesterday.  Took just over an hour.
