Hi all.
Seems this ongoing phase noise issue is getting abit stale don't get
me wrong I understand that all amateurs strive for the importance of
having clean/ noise free transmissions without causing other operators
undue interference.
Also I understand the importance of a low noise floor for vhf weak signal
work
as I am a keen 144mhz dxer with low power that is 50w max,so the thread is
interesting to me as I am contemplating a XV144 to go side by side with my
K2 #4785 to run around 15/20 watts out here in europe.
If i remember when I first encountered information regarding the K2 I was
reading
a QRP magazine and it was claimed the K2 was developed as a high performance
QRP tranceiver along with the K1 that I am also the proud owner of.
It has been well documented that the K2/K1 works very well in this role (I
AGREE)
It seems that some operators are having problems with magnetic interferance
within the pll circuit & various ways to protect this circuit with
sheilding,please take
time here to think that most of the top range black box tranceivers that are
on the
market today probably have more money spent on their sheilding and imunity
to strong interferance than the total cost of the K2 plus a few options.
Please dont get me wrong as I do not have the test equipment to test for
some of the recent issues under the above topic nor do I have the experience
to carry out these tests,but i am pretty sure that synth phase noise and the
recent
change in topic regarding magnetic interferance are slightly different.
All the best rant over Hi.
