K144XV + K144RFLK issue

HI All

I dipped into the Elecraft world again with a K3/10

Plus Tvtr IF and K144XV

Mainly as a transverter driver

I bought the reflock for the radio and the transverter

All is fine and my box is alive and well

Just installed the K144XV and I notice an unusual change in receive freq when looking at a local beacon on 144

Every 3 secs or so it jumps about 10 Hz high or so then returns back to its normal freq - then 3 secs later does the same again

not sure why its doing this any advice appreciated

I have done all the cal routines and the main unit has 10 MHz applied and is locked - flashing * on the cal entry

I only just purchased it so I assume the firmware would be the latest?

Thanks

Simon ZL4PLM

Re: K144XV + K144RFLK issue

Hi Simon,

can you check if the behaviour is the same if you unplug the 10 MHz source?
I have the K144RFLK myself and don't see that behaviour but I do not use an
external 10 MHz reference. To me it seemms like the jumps could be due to
frequency correction calculations from the external reference. To confirm
that just plug it off and see if it still is the same. Just a thought ...

Re: K144XV + K144RFLK issue

Simon,

Do you have another 2m receiver, or know somebody who can receive the
beacon, to check whether or not the beacon's frequency is jumping. If the
beacon's transmitter is crystal controlled with the crystal in an oven, the
jumps in frequency you hear could be due to the beacon not your K144XV.
Been there :-)

Re: K144XV + K144RFLK issue

Geoff

no def the K3 thats jumping - no movement on the DEMI tvtr/IC7600 or the IC9100

the beacon is well known to me and used daily as a propagatation checker - it does not have this characteristic

thanks for the tip though :)

Cheers

Simon

This is likely to be a firmware issue and is on my list.

Hi Simon,

Rich did some tests in March and theorized that there's a problem with
the K3 firmware, not the K3EXREF or the K144RFLK modules. That put it
on my firmware list, where it is still listed as high priority. I took
a stab at it back then but couldn't duplicate anywhere near the
reported jump size. As I recall, Rich was seeing about 3 Hz on 6
meters and 10 Hz on 2 meters.

I have another theory, too, and I've asked Rich to do further tests.
I'll get back to you when I know more, possibly as early as tomorrow.

Wayne

Re: K144XV + K144RFLK issue

Hi Wayne

Yes I am seeing large jumps 10 Hz or > at 144 for sure. I know that others are seeing jumps too and at 6m and 10m too.

Appreciate you picking this up

be great as at the moment that kind of jump every 3 secs makes weak signal digi modes difficult and even listening to the local beacon darn right annoying and the transverter pretty much useless for my use just now.

happy to act as a tester - please shout

Thanks

Re: K144XV + K144RFLK issue

In reply to this post by wayne burdick

Hi Simon
I use K3 with K144XV and K144RFLK with an external 10MHZ GPS locked signal adn have done so for 9 months or so now.
I have never seen this characteristic you describe. I can leave it on GB3VHF beacon using JT65 / WSJT and it stays rock steady at 3Hz discrepancy all day long. I have never noticed any jumping you describe.

Re: K144XV + K144RFLK issue

Hi Roger

Hmmm thats interesting .. I wonder if its something hardware related then?

I know I am not alone and some others have the same issues -so not just something locally in my station.

Its not ext 10 MHz source - I have tried 3 different sources and all do the same as does my Rb standard too.

Every 3 secs it jumps a good way ... at last 10-20 Hz if not more ... I have not measured it exactly but its very audible.

Im keen to fix it for sure ... if I knew how!

Cheers

Re: K144XV + K144RFLK issue

In reply to this post by Simon Lewis-6

Hi Simon,

I also have no such issue, not on 2m not on 6m and also not on 10m. In the meantime I made about 3 times a firmware upgrade since I have the K3. But I also don't see this issue in the older ones.
I see that elecraft works on the issue. But I wonder because some K3's don't have this issue...maybe not only firmware, but firmware/hardware issue.
