[600MRG] Return of the TX --> KL7 path

[Edward R Cole]

John,

Thanks for the reminder to get my inverted-L repaired and back 
up.  Using NOVA as source sunrise is 13:21 (5:21am) and sunset is 
07:01 (11:01pm) so we are getting a few hours full darkness, now 
(17:40 hours of daylight).  Of course Laurence is 70mi north so his 
times are a little longer for sunlight (but only minutes).  We are 
now more than a month after soltice.

Southcentral AK: Anchorage and Kenai Peninsula are blessed with a 
mostly lightning free climate so we do not have the summer static 
crashed you do.  Wx is turning to predominant rainy season of 
Aug-Oct. (ends when it is snow).  May-mid July is the dry sunny 
season up here.  Since we had almost no snow last winter conditions 
are extremely dry and have just about broken the wildfire 
records.  Over a million acres have burned.  Danger for us in 
Southcentral pretty much over.

I remain only able to transmit >495 KHz as I am waiting to raise the 
cash to buy two synth ($219.95/ea) for my K3 Rx and subRx.  That will 
enable running at 472-479.  I can receive lower with my SDR-IQ.
