Hi Steve and Karel,
On the 9Y4 (ITU Reg.2) the band 5250 – 5450 kHz is allocated on a secondary
basis to the Amateur service. Maximum output power is 1.5 kW...
The best way for US is to use ch5 / 5405kHz.
In case of split operation it is commonly used ch4 / 5373 for TX and lsn up on
ch5 /
Hi Pete,
i am using for years the Extra Heavy duty 10m fiberglass pole from DX-Wire (the
only GRP Mast "EXTRA"
heavy duty "strongest" mast with 18mm tip section!) and I can recommend it as
the strongest pole
I ever used. It has nothing to do with tiny poles available on the market...
Hi all,
I have the same experiences from this weekend during the FOC Marathon on
Topband. I heard the same in case of G's and other coastal stations > it did
not happened with sigs from inland stations... the difference was few S units.
Even more I noticed another "SDE" phenomenon this weekend
Rune
maybe this will help a bit.

Hi all,
I can confirm Martin's and Greg's experiences. It is strongly recommended to
avoid
using the PLs at all. I did the same changes and since that no problems at all.
Of course any adapters are avoided too. All cables must be properly assembled
with proper
and high quality N-connectors.

Hi all,
the split JA operation schema for decades ago was:
JA TX 1907.5 - 1912.5kHz and listen for rest or worls in between 1820
- 1825kHz.
This JA window 1907.5 - 1912.5kHz has been not used in contests from
1999 by JARL
because the band was too narrow. The SSB was not permitted.
