It has never been difficult to get a QRS 3 signal into 4X4RF or TF3HZ =
or Moscow area and even CW.
It seems most are bashing away in QRS120 most of the time when QRS 3 =
would do the trick.=20
I worked UA6LA on CW two way 136.5 Khz March 2005 for the first time.
also it is possible to be been seen at TF3HZ during daytime and I have =
also worked OH1TN many times during the daytime on 136.5
Faster speed are preferable to beat QSB. This is my approach and if it =
does not work then I slow down if necessary.
On 160 metres especially winter time I can work UA9 stns daytime from my =
QTH and I would say it could likewise be done on 600 metres if anyone in =
UA9 was available for a QSO.
To achive good long haul results on LF es MF good Antennas and =
sufficient power is essential, this also helps avoid the QSB problem.
