Hi Andrey

Congrats on reception of JA7NI!  He has a very effective TX vertical=20
some 50m high with top loading and with 50W input.

His RX situation is fairly good but he is troubled by local QRM which=20
often limited results during our tests.  He used some beverages=20
optimized for top band use for our QSO but I believe he has been working=
=20
hard on a loop antenna for RX as well.

Lately you'll notice the huge T-storms near JA and HI.  These have been=20
limiting my hearing as well during times of mutual propagation so I=20
would imagine the JAs are having trouble hearing DX as well because of=20
this weather.

With respect to frequency coordination this topic was broached during=20
our testing and it was decided not to use the 136 portion of then band=20
then but the idea was considered for future use.  Discuss with Yas as=20
Kuni is capable to QSY quickly on TX as he lives at the transmit site. =20
However, his RX station is in the mountains some distance from his home=20
which may complicate things if changes are needed there...

73 es GL!
