Hello all
I just purchased an Ameritron ALS-600 amp which does band switching. For
bandswitching, they suggest interfacing it with the K3 through their ARI-500
( for cabling reasons).
This set up for the K3 uses the ACC LP Key Out pin to key the amp...not the
Key Out RCA jack.
The Amp will not
Joe,
Use the ACC for the band switching connection and use the KEY OUT to do the
PTT. In other words, separate cables.

Just checking to see if there are any last minute Dayton Specials from

I would like to find or build an external speaker for my K3. I want something
that sounds good,will match closely and is realitively efficent like 92 db @ 1

I use a pair of amplified Labtec computer speakers. They
sound good, have convenient headset and mike inputs, volume
and balance controls. I don't think they look
particularly good, but you can find computer speakers of all
types. Some you will need to RFI doctor with ferrite beads.
By match closely, do you mean physical appearance or impedance?
Speaker characteristics for SSB and CW may differ. The best overall
compromise I've found over the past 45 years is the Heathkit HS-1661. It is
very efficient, as in LOUD, has a thick aluminum cabinet with no vibration

Go for two, then you can take advantage of AFX.
I use two small black communications speakers, designed for vehicle mounting and
optimised for voice and are only 3-4 mm taller than the K3 -- one either side.
Really does enhance AFX on SSB and they look good too. And they were less
than GBP 7
Caution! Do -not- plug a mono plug into the external
speaker jack. Audio output IC failure will likely occur,
as a mono plug shorts one half of the IC.

This can only happen if you have CONFIG:SPKRS set to 2. If you set it

I am using a Jetstream JTPS28M and I am happy. I have a few birdies, but I am

Merv, if you're suddenly getting hash from two formerly-clean switchers, I'd
suspect something else, such as a bad mains ground on the circuit feeding

But if you do that, you won't be able to take advantage of your narrow
filters for PSK31 etc. because your filter will fall outside the passband.
Looks to me like you better leave your FC where it is at 1500 Hz unless you
like hearing wide spectrum and don't mind the QRM.

Hi,
Has anyone else noticed the screws that hold the K3 case together appear to
rust over time?
Not a show stopper but they do look a little sad one year on.
Yes I could drop some black hobby enamel paint on them but this seems a little
odd to me that after just one of owning the radio now
Please pass over my previous post about pitch. You can indeed change FC and
retain use of narrow filtering. Just remember to change the FC in whatever
software you're using.

I have not noticed any rust (haven't had the K3 outside the home). However,

Merv,
My experience with the FT-1000D was that the S-meter didn't start to move
until the actual signal strength reached S-5 or so. But yes, I believe you
when you say that the switching power supply creates a lot of noise, and the
one in the FT-1000D doesn't.

Yes, the low slope (and perhaps the threshold) for my AGC settings
increases the apparent NR distortion. So you have to make a decision
better AGC response or clearer audio when using NR.
Since I rarely use NR, I have made my choice.

Sorry but this is totally wrong. In this case your FT-1000D
was either broken or not aligned properly.
If you still have it align it per the service manual and
you will see something totally different.
