Hi Bob, ( and Reflector readers)
If you have a look at the Control board diagram, you will see
that RP3 is 5 x 47k individual resistors. The one I took out is also
correctly marked "A 473G"
RP3 1/2 is used with U10a in the ALC circuit
RP3 3/4 and 5/6 is in series with the sidetone c
Due to antenna restrictions, I am thinking of controlling my K2 remotely and
would be interested in any advice.
I want to run the K2 control software from my home computer and connect to the
radio over a virtual serial port via telephone or UHF link. I could use a
second phone line or UHF lin
I had a problem with my K2 with low audio as well, after more than a
couple years of no problems. I had used many headphone sets in that time aiming
at the epitome for me.
In my zeal I had exercised the phone plug too much, a call To Elecraft
pointed out the cure: it had to be replaced. It

Check out http://www.trx-manager.com for rig control and
http://www.skype.com for audio.
Both work great. TRX Manager can be controlled over tcp-ip and skype
does an excellent job with audio. You really need a high speed
connection for it to work well.
I'm currently running a TS-480 via

Thanks for the info. I'd like to avoid tcp/ip if I could because of what I
assume is the latency involved. I want to operate a remote radio and yet still
want to have QSK CW. Does your set-up allow QSK?
I don't have an internet connection faster than dial-up and doubt I could get

John, the only way to do what you want and have the control software at
home is to use a serial device server. There is info on this on my
website as Richard mentioned.
Serial device servers can either be hardware devices or software run on
a remote computer. I use the hardware approach. I got

The only way to avoid TCP/IP would be to set up a dedicated twisted
pair between your place and the remote location. This is a very
expensive solution, and I'd bet you really don't want to spring for it.
The reason that you really need to use TCP/IP is that it is the only
protocol suite tha

Even this uses TCP/IP, something John thinks he should do without.

Hi Folks.
I have several questions regarding the impedances involved in the K2's
I.F., and their impact on the design of the KSB2's filter and matching
transformers. I poked around the K2 mail archives and saw a similar
question posted some time ago

Yes Jack, you're right... obviously some kind of encoding is required. I
guess you could invent you own, maybe using fsk, but tcp/ip is there and
it works. I think he may be saying he wants to avoid an internet
connection. I had excellent results using ISDN... high quality audio,
low latency, t

Just a random thought. Since you mentioned that several resistors
marked as 82 Ohms came in around 130 Ohms: Have you verified that your
Ohmmeter is giving you a correct reading? For example, have you checked
it with other (new) resistors marked with different values, or compared
I'm using a SLA150 on my K2 and it works fine. I get about
120-130 watts out on most bands. The auto - band detect
works fine, and unlike the cheap-o CB amps, there's tuned output
for each band.
I'm sure the KPA100 is fine too, but the SLA is a workable alternative

Hi folks
I Have a K2 and I finished the part II of RF board.
I think that the receiver is working fine because I connected an antenna and
I heard CW signals.
The problem is that if I touch any button the receiver stops working and the

But if I tap the MEN

With K2/100 100w out after two QSOs on 40m overall about 40 minutes the BL1

I just finished building a KAT100 and KPA100 in an EC2 for a friend. This
is perhaps the best way to go if you still enjoy taking your QRP K2 out into
the field. Bill's K2 has the KAT1 and KIO2 in the basic radio. Now when
it's on the home base, just 2 connections and it's running QRO with a QRO

Hi John:
I understand your concerncs.
I don't think qsk is going to be possible with any method due to the
latency.
I used to run a Kachina via the phone lines and there was a bit of
latency. I also an ISDN line for the Kachina and there still was some
latency.

(easy, once I figured it out), the filters are set (Spectrogram makes
this a snap), and I've made enough QSO's on it now to pretty well shake

Anyone out there using Lithium AA cells with the K1
internal battery option (KBT1)?
I originally purchased the KBT1 but sold it before I
installed it because I felt that it would be too much of
a hassle to remove, charge and re-install NIMH cells
all the time. Now after using my KX1 for some time

Thanks!
