Yes, that was the problem when it happened to me. It was a cable problem
that was inadvertently closing the key in (PA Key) input on the back of
the KPA500. Clearing that up restored normal operation.

Hi Barry,
While your experience suggests that a transistor switch will probably save
the day I also wonder if the problem is the result of the absence or
presence of a pull-up resistor or perhaps a floating common connection
between the rig and amp. Maybe a resistor in the plug would help. I
I'm using a Pixel Loop as a receiving antenna to supplement my main t/r
antenna, which is an R8 vertical. The only 'garden' I have is a rooftop about
35 m above ground. The antenna is about 6 m from the vertical and definitely
has a better s/n ratio. I use it on HF bands, sometimes by itself
when I switch it from
Stby to Oper, the level of received signals drops by around 5 or 6 s
points. It still transmits fine and there are no adverse SWR indications or
loose co-ax plugs. It does the same on all bands.
Sounds like bad PIN DIODE situation, but I'll let those who are more

Looks like the Kenwood switches high during transmit and the KPA500
requires a low for transmit. KPA500 specs in my manual say +5V max, open
circuit on receive, closed to ground on transmit. My old KPA500 manual
doesn't show Kenwood interconnections. Only the K3, Yaesu and Icom.

Hi Jim,
I can't have explained myself very well. The NB is working (level 10) on
the P3 but on the VGA output the NB on state is not remembered on switch
off. So if I turn the P3 off and then on again, the NB works fine on the
P3's own display, but to make it work on the external monitor I

they would. And, Fusion’s name doesn’t help, either. Clicking

There are two menu functions associated with the P3 NB. One is the

Try a K9AY for 40/80/160 or maybe a 5' x 5' passive magnetic loop for
160M. Array solutions also make another variant on the K9AY which may be
superior - I do not know.For the low band receive antennas can be a
considerable help and for 160M are a must if you want to hear on this

Forget about Ed's prowess in ham radio! Let's talk about something really

Hi Paul,
A lot of K3 owners are using the Pixel Technologies loop antenna. I'm
pleased with mine in comparison to my SteppIR vertical antenna on 80 and 40

beneficial when used with the K3 sub receiver as a diversity

I've had an Alex Loop for about 2 years now, it replaced my Buddipole
[about the same cost]. You can build your own mag loop for a lot less
than the Alex but I wanted the cool carry case and had the $$ from the
BP sale. :-)) I use the loop when activating a SOTA summit and general

I have used Andy's (Wellbrooks) antennas commercially for receiving MW and they
are excellent! You will see one of the installations on the web site.

Well, since the subject is K3 and RTTY, isn't it fairly safe to assume that a

What is the status of any firmware change to allow digital mode per
VFO on the K3?
Not likely due to the synthesizer design.
Meantime are there any workarounds?
You can certainly use AFSK (MMTTY USB) and PSK63 (MMVARI) or 2 x MMVARI
simultaneously in DATA_A - one on each receiver/VFO.
73,
The simplest workaround is to use AFSK. If you are capable of
configuring your equipment so as to generate a clean PSK63 signal, it is
within your ability to use AFSK to create a clean RTTY signal that is
every bit as good as (or better than) an FSK RTTY signal.

Hi Barry,
There is an asterisk that appears on the left side of the KPA500 display
whenever the key out signal from your transmitter is present. You should not
