GA Peter,

 

I had something similar happen to me some time ago and if memory serves me correctly, the cure was a compete reinitialization of the rig.  This meant that I would be starting over with no memories or configuration except for the default as provided in the reinitialization.

 

So before you do anything at all, talk with Elecraft support first. It would be the best thing to do.

 

Best regards,

 

Jerry, W1IE

K3 frozen

Pete Barletto
 

When I turned the rig on today I was greeted with the following error code: E04004C ERR DSC.  After consulting the manual the suggestion was to reload firmware.

I fired up the utility and downloaded the firmware and instructed the utility to load all (I was at the current level 5.67).

The result is shown below - the key seems to be the lack of an echo of D at 1641.52.
At this point the display shows MCU LD.

I removed power and tried again but the display continues to indicate MCU LD (and it's dark) and the TX light is flashing about once per second or so....

Anyone have this before?  And how did you recover?

Thanks,

Pete // KU2C

Re: K3s frequency drift on HF

barry NF1O
 

I was very surprised as well, not something that is expected. several people suggested dirty up/dn switches and after looking, i found the only place they could be was the mic connector.  The frequency shifting was constant, very slow but always there. I plugged in a mic connector with no mike or anything connected to it. The problem immediately stopped and has not returned.  (I keep a dust cap on all the time now)
very strange, but in my 35 years working in engineering I have found the occasional solution that did not appear to make sense.
good luck.

Hi Barry, that sounds unlikely but I will investigate, I like you use a headset in the rear Jack. I was leaning towards the encoder, I thought maybe the mouse wheel via N1MM but I disconnected the USB and it still happened.  I will check that when I get home.

Re: K3s frequency drift on HF

I had that happen to me a while back. some suggested that the up/dn buttons on the mic could do that. I had always used the rear mic connector so did not have up/dn buttons but it did look like thats what was going on. I plugged in a mic connector into front mic and problem immediately stopped. Apparently enough dust had collected in the mike port and provided a low enough resistance to cause it. I now use a cover on the mike port.

Hello,
My K3s has developed a drift problem whereby not only does it drift, but the frequency readout goes with it. It seems to be temperature related as  with the fans on auto it was drifting in one direction and when I put the fans manually on top speed it drifted the other direction. Any ideas please?

Hi Robert, this is not normal drift as much as involuntary QSYing. It is randomly intermittent so is a fault rather than normal drift. Last night I was struggling to have a contest QSO on RTTY before it wandered off.
I’m wondering if it is to to with the VFO encoder but shifting it doesn’t have the affect of making it better or worse.

Re: What’s my K3 worth

Paul G4KZY
 

Just a data point.  I bought my older K3 serial no. 12xx for $1850 earlier this year.  That price excludes shipping costs, which were quite high from the USA to the UK.

It does not have any K3s upgrade parts but is almost fully loaded with 2 receivers, 5 crystal filters in each receiver, 100W PA, KAT3, KBPF3, KIO3, KXV3, KDVR3 and KTCX02.

Before I decided to buy, it was on sale for a week or two for $1995 including shipping to CONUS without any takers.

I am delighted with it.

Good luck with your sale,

Paul G4KZY


Re: K3s frequency drift on HF

Robert W5AJ
 

Mike,

 

need bit more information

Normal here on warm up, the K3 does drift in one direction, how much is your rig drifting

The room is lower temperature than K3 and turning fans on does cause (less than 1 hz at WWV 5mhz) drift in other direction

(that’s here in my shack)

 

In preparing for FMT, leave the rig on from time you arise

Don’t put fans in manual before test, leave in normal

also do your pre-calibration checks with WWV same and not after heavy RTTY or FT8 pileup!

 

drift is hardly noted on 160meters, more as you go to higher band.

Re: K3, P3 & an SPE amp.

This is absolutely the right way to do it! And it's true regardless of the rig or the amp in use.

BTW -- with a wide variety of rigs and amps (five rigs, four amps), I've never even hooked up ALC between a rig and an amp.

In general, it is a very bad idea to use ALC to set output power with a power amp -- it is a recipe for serious intermod distortion (clicks, splatter, etc). Indeed, this has been true for at least 40 years.

ALC between amp and rig should be used ONLY to protect the amp from problems in the antenna system, including operator switching errors.

Re: K3 update

Bob McGraw - K4TAX
 

I suggest three things:  (a) using the K3 Utility, make a backup of your radio configuration.  (b) using the K3 Utility, download the latest version from the Elecraft site and install same into your radio.  (c) after install make another backup configuration.  {they will have different time stamps.}

I check for updates at least once a month on everything on my radios and my computers.   And I always make regular backups of the computers and radios.  Failing to do this is much like jumping out of an airplane and then realizing one forgot to put on their parachute.   It's then way too late to do anything about it.

Re: K3, P3 & an SPE amp.

Hi everyone,

a big thank you to everyone who took the time to reply. I have it working, well works but another issue has popped up unrelated, well I don't think it is related.

Using the mic ( a Kenwood hand mic) the rig will not unkey when I let the mic button go, same thing happens when I key up on CW it is 'holding' the ptt line down. I need to power cycle the radio for it to release. It has only just reared it's head and I have not even started to research it yet. I just wanted to say thanks whilst I remembered to :-) I also noticed monitor must be on too as I get my audio playing via the inbuilt speaker as well. 

As already mentioned the K3 is a very recent purchase, all I have really done is update the firmware. The CPU had been reset prior to getting my hands on it so I have not really had the time to get it setup yet. No config file available from the previous owners. We have a public holiday weekend here so I can continue to get to know it a little better over the next few days.

All noted on the ALC, to be honest not something I trust using and have always used the power level on my radios settings to control power going to the SPE. Something I will continue to do with the K3 as well. 

I have a learning curve ahead of me similar as when I got the Flex Radio a number of years back I guess.

Again, thanks for the input all, it is very much appreciated.

Regards & 73

Hello Tim; I also wonder how well the K3 ALC input from the SPE amplifier responds. ie, The SPE manual says to rum full exciter power to the amplifier input and the ALC will adjust accordingly. Elecraft says not to rely on the ALC to reduce K3 power output to the amplifier. I also have a recently acquired SPE amplifier as well ,and a KPA500 currently connected, but have not used the SPE with my K3s. de Mike K8NS

Hello everyone on list.

I recently purchased a K3 along with a P3. Working beautifully. 

I also have an SPE amp (2k-fa) which I have connected to my other radio, a Flex 6400M.

I am wondering if someone can point me in the right direction as to how to hook the SPE up to the K3?

The RS232 on the rear of the radio is already hooked up to the rs232 port on the P3, is there an adapter I need to purchase to 'split' the rs232 port or has anyone got a diagram handy to make up a cable to do the same thing?

Apologies in advance, bit of a learning curve for me and no doubt I will have some more mundane questions from time to time.

Thanks in advance and 73.
