I pondered the question of kit or factory for several weeks before deciding
on the factory built. I have not seen a list but my reasons were the initial
calibrations properly done and the proper fit was attained while assembling
all pieces. That said when I got it home I partly disassembled it and
I know this has been covered before but I can't find it. Please repost this

I would favour building my own, Ralph. There are no 'benefits' in
factory built other than it costing more and not providing the
experience and confidence of making adjustments as and when required.

if you know how to tell the hot from the cold end of a soldering iron you
can build one yourself. I already described it in the German FUNKAMATEUR
magazine back in 2011 and FUNKAMATEUR is also selling a kit. It plugs

I recently tried this with some no-name BT transceivers. Using just the
BT in my Mac, I could not connect to the devices. I did not try going
through a serial-to-USB adapter as that would occupy another USB port
which is what I was trying to eliminate.
I also tried experimenting with a

Has anyone used a Bluetooth to RS232 Serial adapter, such as the dongle
style that could plug into a 9-pin connector (but, it does not have to be
dongle style).
No, but I use a blue-tooth connected headset and it works great for moving
about the shack whilst chatting (VOX on)!

The MAX232 generates its own RS232 voltage levels from a +5V input. It has
two drivers and two receivers on one chip, the receivers are good to +/-
30V.

Hi there,
while participating in the Georgia QSO Party, I noticed some interesting
weirdness with the DVR repeat. After a number of repeats, rather than
playing back the message it just goes on TX and no message is played back,

I purchased my KX3, #3508, factory assembled and I feel it was well worth
the additional $100. Actually,it is quite a bargain after reading Eric's
reply. I do have one question for Eric if he checks back on this post. My

The extended temperature compensation calibration is not done at the factory.
The rig includes basic temp compensation.
I got a kit, partly because I did not get the roofing filters. Without those, a

How do roofing filters work on a direct conversion radio? That's not a
snarky question, I don't know and would like to.
Fred,
My understanding --
The roofing filters are at baseband (audible frequencies), but are
inserted prior to the conversion to digital - that means the DSP will
not see content outside the roofing filter range and the possibility of
overload in the A to D conversion is greatly reduced.
The roofing filter is actually at AF ahead of AF amplification and A/D. So
basically it is roofing for the DSP. Pretty amazing.

Like many terms in Ham rigs today, roofing filters have taken on a whole
new identity that, in this case, has very little to do with their original
function. But there's a tenuous connection, just the same.
As you probably know, roofing filter referred to a filter in the VHF

I have noticed the same thing during the Georgia QSO Party that I'm working
right now.
Sometimes it goes to open mic after first repeat, sometimes it's the
dozenth, and anything inbetween. I have to kill the repeat, and start very
very odd. Can't tell that there's a pattern.

All I can say about the filters in my KX3 is that they work and very well I
might add. This little radio never ceases to amaze me every day that I own
it.

I just installed the P3SVGA option and am having a lot of fun programming the
text message and K3 macros. But I seem to have lost the display of the P3
function keys assignments that I normally see at the bottom of the P3 LCD

Yep. There's many real advantages in the direct conversion (d.c.)
architecture. Note that the popular regenerative receivers of the 1920's
were direct conversion. Like modern receivers they heterodyned the signal
frequency directly to audio. When they were rediscovered in the 1970's

It shouldn't affect the function key assignments. You do have the FN
labels turned on with the LABELS key (hold key), right? The only
other thing I can suggest is maybe the EEPROM wasn't read properly after
cycling power for some reason. You could try cycling power again.

Hi Alan,
Somehow(he says innocently), in setting all the new SVGA settings and pressing
the menu key many times, I held the menu key too long and activated the

have now re-enabled the labels.
