Good Morning, Yeah, not sure what happened but appears when in
high power mode over 10 watts power control does not work either.
It gives full output. I just replaced diodes D1 and D2 1N5711s but
the problem continues the same. Before I get any deeper into this does
anyone have any experience with
The problem is the terminology, John.
In this case FSK and PSK should have been read as ASCII and
Morse code. The translation from ASCII to Varicode to PSK and
vice versa as well as ASCII etc first to 5 bit Baudot and then to
FSK is done by software in the radio itself, as opposed to software
Sorry that should have been D16 and 17. I'm going to look at the
circuit again and again. 73

I had a failure of the EL5146C op amp. You might check it. In my case, mine
shorted internally, which brought the +5 volt supply to zero, which made the K2
think the KPA100 was not installed. But, yours might have opened or something.
I think D16 D17, as well as the EL5146C might be pretty
Hi all,
My KRX3 is on the truck and due tuesday. Quick question: I will be running
the main receiver on a receive only antenna
fed via the KXV3A and the subrx via its bnc aux. These antennas are quite
close to the xmit antennas. Should I use
any sort of attenuation and/or external TR switch
Mike,
Check the power control 5 watts requested. If you actually get more
than 10 watts output then either the diodes (I understand you replaced
them) or KPA100 U6 may be the cause - there are a few other
possibilities too.
During a TUNE, you should have voltage into U6 pin 3, and

the only volume control is on the blue tooth transmitter which does not

the subRX of the K3 has its protection (an rf triggered relay if the
power coming into the rx is too high).
I've used the K3-KPA500 on a beam and I had a diversity vertical
connected to the subrx quite next to it. No problem at all.
It all depends on the coupling of the antennas. Try

I have a similar setup as Arie - an 80 meter Inverted L at 40 feet for my
transmitting antenna and a Hustler 5BTV vertical ground mounted about 10 feet
from being directly under the vertical. Works fine. If I crank up my KPA500,
the relays in the K3 quickly isolate the subrx from too
Jim and Steve,
While the COR will do its job, I recommend that you not abuse it. If you
hear the COR operating during transmit, it would be wise to provide some
external switching (relay) to remove the RX antenna while transmitting
or insert an attenuator.
Of course, the best solution is to

What happens if you plug the Bluetooth transmitter into the speaker jack
on the rear panel? It is worth a try.

I have the following setup:
K3 (with two receivers)
P3 with SVGA
Steppir 3 element Yagi
External monitor attached to P3
I am having problems with the P3 SVGA being sluggish and periodically locking
up. Sometimes the external monitor locks up, sometimes both. I can usually
get it running
I have this happen occasionally, but only when I am transmitting with the
KPA500. In RX and barefoot, it's solid. I'm going to try some additional
snap-on ferrite chokes on the lines, etc.

I saw a suggestion somewhere for using a small grain-of-wheat bulb across
the 2nd antenna's lead as you gradually increase transmit power. If I
remember correctly, the bulb I used was a 5 V @ 50 mA lamp, typical of those
used as LCD screen illuminators.
I tried that with a 600 ' Beverage
I seem to remember it is not recommended to attempt to use a usb hub in
the P3's SVGA USB port, can't find it now that I am looking for it. :-/
my question:
would this hub with on/off power switches for each usb port work?

it says:
Hi Sam,
The USB port on the P3/SVGA does not support hubs.

Dick,
You did not indicate if the feedback is in the internal K3 speaker or
an external speaker. I have no problem with my K3 using an ext. spkr
(but that is because it is unamplified 1950's era National 8-inch speaker).
I do get audio feedback with my KX3 because I am using cheap computer

Using audio out from the rear speaker jack is the same as the front
headphone jack: low audio which becomes distorted as the gain from
either the radio or the BT transmitter is increased. I'm thinking that
this might be a limitation in the hearing aids. I haven't

Hello,
Have you always wanted an Elecraft? A KX1, K1, K2, K3, whatever?
I build and service them all!

Jim,
I do not know the practices used at Watsonville, but I can tell you mine.
I do much of the repair work on legacy Elecraft gear (K2, K1, KX1, XV
series and other thru-hole kits). I always attempt to return the gear
in the same carton it was shipped in. Exceptions will be when the

Hi, George. I reported a similar problem here on the reflector in early
December:
-
I am using a P3 with the SVGA option. It is connected to a K3. I find that
frequently after transmitting -- particularly calling a DX station in a
split-frequency pileup -- the P3 display comes back sluggish
Hi all,
The KX3 is primarily an HF-6 meter radio. But it does have useful sensitivity
in the 500-1700 kHz AM broadcast band (or BCB for short).
I'm looking for a few testers for a new firmware release (rev 1.84) that can
improve AM-band sensitivity by as much as 10 to 20 dB for stations below
I am sorry.
I didn't specify that this was not Elecraft who was involved. I was asking
a generic question about experiences vs. what I have had in two cases. One
was not an issue but I consider it just plain lucky that the other arrived
back undamaged. Thanks for all the comments. Again,
I do the packing and shipping of Rose's dust covers and
carrying cases. The total is nearing 2K packages, and
with only a couple of exceptions -all- have gone via
USPS Priority Mail and usually reach their destinations
in two to three days. Priority Mail now provides tracking
numbers, BTW.
