Brian,
In later XV transverters, JP9 controls when the crystal oven is powered.
Since you do not have JP9, even if you have a crystal oven, it will
still work fine.
The oven will be powered when the XV50 is powered. Just allow some time
for it to warm up (about 20 minutes).
Actually, the
Although you can certainly use it just for charging an SLA, one advantage of
these types of chargers is they automatically go into float mode to maintain
the charge and prolong the life of the battery. This is particularly
beneficial for batteries that go fairly long periods of disuse, like
Hi Jim,
Excellent article. I haven't checked if it is a source of noise, but it
doesn't quite matter because this is a charger, not a power supply. I only
use it when I need to charge a battery, so it is OK.

Have you checked it for noise, using techniques in this app note?

I'd bet you would if you tried.

I don’t disagree with K4TAX. It’s up to the operator to work out RFI at one’s
station.
But for the sake of clarity to those that may read this thread later…
The rigs in question in this part of the thread are the K4.
Every component of my station is bounded and grounded per K9YC’s
Hello - I recently purchased an XV50 to use with my K2. While setting it
up for a K2 with no K60XV per the manual, I noticed that there is no
JP9, where I am supposed to short pins 1-2. On closer inspection, my
XV50 has a rev B board and it appears these pins don't exist. The

Also the K3 memory editor can read the memories and send them to a K3.

Does anyone know of a way to move the macros programmed into one P3, to
a different P3, not by simply retyping them into the new P3?

Running my K3S, KPA500 and working 160M - 6M at 500 watts, using either
a mike into the front of the radio, or my headset into the back, I
experience NO RFI issues. I don't have any toroids on any cables
either. I also run digital modes with a single USB cable between the

Hi Doug,
I use this, and it seems to be working very well. When you order, make
sure you specify a 14.8V (or 14.6V) model.
Some reviews complain that the voltage measurement is only 12V, but mine
clearly shows 14.8V on my Fluke meter.
With such an out of balance antenna, the case, power supply and leads of
the transmitter are all going to be parts of the real antenna. I'm not
sure, therefore, that you can rely on an SWR measurement made using
other equipment.
You should certainly make sure that paint is removed from
I use a small wall wart type lead acid battery charger/maintainer as the type
