Warren, LF,
Tnx for the info!
I am not "afraid" that now many OMs come on the band who just bought their rig,
like on HF. Even if you could buy a loading coil, you never will get qrv
satisfactorily cause you always have to consider many things like the earth,
the local noise reduction, the impedance transformation to 50 Ohm and so on.
These OMs, even if they could buy a automatic tuner (that would not be easy to
create as a commercial product) for LF, would be frustrated soon cause there
are no contests and no 100s of stns calling on the band ;-) They would say "LF
is dead, just nerving qrm" and would never get the fascination that we all
experience.
Finally I don't understand why this PA has just 100W. To reach 1W ERP, most
LFers have to apply 1kW and more, so 100W is QRP on LF ;-). 1kW can easily be
reached on LF without using expensive special transistors and drivers and
ferrite cores. E.g. with one simple IRFP360 we can built a 1kW high efficiency
calss d or e PA that costs not even 50€...
These difficulties to get qrv is one part of the LF hobby and if they are
solved, one can be glad even without doing 100s of qsos in one evening :-)

Betreff: LF: TX-2200A
Interesting new rig offered by Waters and Stanton - the TX-2200A 100
Watt class D transmitter for 136kHz - VFO controlled with receiver
muting.
Made in Japan, relatively pricey though at 690 GBP!
