Any interest in a functioning, good condition QRP+ V1 with a Index Labs Companion (also fuctioning in good condition)

Re: QRP+Companion

 

Ah, yes, the K2s.?

#1? I built the first one myself.? Tuner, Audio filter, maybe a bit more but no SSB or DSP

#2? KK7P the designer of the K2 DSP unit was selling his K2 with DSP, Tuner, SSB etc.? I bought it.
?????
#3? I bought a fairly well loaded 100w K2 since propagation sucks from up here above 61 degrees north. I thought I needed the dB advantage which was probably true.

You all know the old saying, "If one K2 is good then three is better."?? Right??
I do like the K2.? The MDS on #1 (I forget which band) was -139 dBm.

Then the 1st K2 lost its sidetone.? Not fixed yet.? Taken apart and in a box.
The 2nd K2 is just fine at 10-15 watts.
The 3rd K2 I just never got the 20 amp PS hooked up.? I did run it at 5 watts a bit.? Needs a tuner.

I used to "crastinate" but I got so good I turned "Pro-"?? :-)

Take care

Hi Jim and Dave,
What fun watching you two talk. I hear 17 Meters is not bad and is coming to life. I have not been on in a while.

The QRP+ files referenced in some emails you have posted today contain info copied directly from my .? Why not just post a file containing a link to the site?? That way people could see all of the information.

You can attach an LED to he meter as described .? I have seen information on replacing the display with a back-lite version but I am unable to find that information now.

QRP+Companion

David KK7SS
 

Another day spent indoors..? :-(
Played with the tuner in the Companion and noticed two things..
1) If the antenna is resonant at the chosen frequency the tuning is almost flat. But
2) if the antenna is NOT resonant, the tuning gets very sharp.
I used my 40M antenna and tried loading up on 60M.. Worked like a charm. :-)


Pcb locations?

David KK7SS
 

I have not yet opened my QRP+ to investigate a few minor mods.
Starting from the top, what is each PCB's function.

Thanks..

Re: QRPPlus cabling

Kees;
About upgrades to the firmware. These would be un-obtanium for most. Unless you had access to the upgrade and an emprom burner.
W1HUE published way back in 1997 (23 years ago) this:

----quoting from the January 1997 QRP Journal -----
Index has made several "firmware" upgrades for the QRP+ available
as new EPROMs for the very nominal charge of S6 .00 plus return
of the old EPROM. The most recent version of which I am aware is
designated "Rev 4C". (Note that this is model specific - the QRP++
may well use a different EPROM.) The Rev 4C EPROM contains
several programming changes that affect the internal keyer and the
switched capacitance audio filter (SCAF). If you do not have this latest
version, you should contact Index for an upgrade. How do you tell if
you have this version or not? Simple: If you did not upgrade, you don't
have it! If you obtained your rig used and don't know its hi story, a
couple of simple tests wi ll determine whether or not you have the latest
EPROM: If the internal keyer speed changes in increments of 5 WPM,
you don't have it. If the keyer speed changes in increments of 1 WPM
but an external keyer cannot be fo llowed above about 27 WPM, then
you still don't have it (you probably have Rev 03).

This is all I know about this. This radio is an oldy but a goodie. The radio would have to be completely redesigned to use a different more up to date processor.
the 80C39.
When I was working at Intel back in the mid eighties this was one of my products.. it is basically an 8051 CPU running at 8mhz. A real workhorse. Most likely this was programmed in Assembler so upgrading this would be a real chore.

More information about the QRP + is located here:
He no longer owns his qrp+, I do... I got it in a round about way.
There is tons of information here. I am not sure how long he intends to keep this web page up though.
