Re: LF: JA7NI and Eu-station

[Scott Tilley <sthed475@telus.net>]

Hi Andrey

Congrats on reception of JA7NI!  He has a very effective TX vertical 
some 50m high with top loading and with 50W input.
His RX situation is fairly good but he is troubled by local QRM which 
often limited results during our tests.  He used some beverages 
optimized for top band use for our QSO but I believe he has been working 
hard on a loop antenna for RX as well.
Lately you'll notice the huge T-storms near JA and HI.  These have been 
limiting my hearing as well during times of mutual propagation so I 
would imagine the JAs are having trouble hearing DX as well because of 
this weather.
With respect to frequency coordination this topic was broached during 
our testing and it was decided not to use the 136 portion of then band 
then but the idea was considered for future use.  Discuss with Yas as 
Kuni is capable to QSY quickly on TX as he lives at the transmit site.  
However, his RX station is in the mountains some distance from his home 
which may complicate things if changes are needed there...
73 es GL!
