Thank you for your very comprehensive reply.
The FT1000MP gets switched on about once a month, and I tend to switch between
bands and functions. This is not an excessive idle time, and I think that if
decent relays were fitted there would be no problem. All relays are not created
I am currently using my K2/100 to drive a linear amplifier (Yaesu Quadra).
I would like to use the ALC output voltage from the amplifier to control the
output from my K2/100.
Has anyone managed to do this, and any recommendations?
Thanks

Peter,
Not practical - you will have to be satisfied with controlling the level of
the drive to the linear.
In most cases, using ALC is not a good idea IMHO because it is normally set
to be an indicator of gain compression which is another way of saying

Hello fellow Polar Bears and all!
If anyone is interested in a Polar Bear Candy Tin, I can take a list for
orders. Click on the link below and look only at the Polar Bear Tin. It
contains Mint Ice Cremes. If anyone wants all five tins, that's ok
too. I will start an order list so we save on
Hi Evert,
First, sorry I missed you in the PACC! I played a
little in it, 160 to 20.
As to your questions:
1) Is there a noticeable difference in heat-sink
temperature when operating on higher bands?
There is a noticable difference if you're running into
a mismatched load. Also, it gets

Sorry for the bad link.
Here's a link to my website for a look at the

Hi Folks,
My K2/100 (S/N 4787) is about 10 months old. My
question is at what point, or ever, should all the
initial alignments be repeated? There are several
reasons for asking the question other than electronic
components simply drifting a bit with age.
1. Recently I've noticed when it is
Jim,
The K2 does not seem to need periodic re-alignment because there is not a
lot of drift in the component values over time and the design is on the
conservative side, so it is forgiving of minor alignment errors.
BUT - If you want optimum performance, do take whatever steps necessary to
get

This should be and easy one. I have a K2, SN543, loaded with all updates

Just saying 'Heil boom set' is not sufficient information to tell me which

Is it the Elecraft MD2? Is it the Heil ProSet (if so, which one of these is
it)? If the mic was made for use with an Elecraft or an Icom, then it
should have an electret element in it, but if
Hello all, I have been building a K2 and now a KPA-100. I am using a solder
pot for tinning toroids and would like to know how often to replace the
solder in the pot. I have been skimming the top which removes flux and
debries. I used a 1/2lb off a flux core roll and found it contains too much
Is there any news on when the new amplifer/tuner kit is coming out? I tried
to ask Wayne and Eric but do not get responses from either. Tried via the
list and direct :(
If not, does anyone know of a decent 10-160 SS amp kit a guy can build or
good plans to homebrew one?
Thanks and 73,
I have a small solder pot, and have had a hard time tinning with it. I'm sure
the problem lies with the user (me) and not with the pot!
I originally used solder from a roll (with flux) as Rick says, but it became so
much of a mess that I purchased a rod of solder (I guess it weighs a pound or
When I last used a solderpot, my understanding is that you generally
*don't* have flux in the pot .. just solder. When tinning a wire, you
dip it in paste or liquid flux and then into the pot. Solder
manufacturers sell bar solder (with no flux) for use in solder pots.

On 2/13/06,
I run a Goot model 22C solder pot (small, about 1/2 lb capacity) - and
do not use fluxed solder at all! I use plain bar solder (available from
Mouser and others) cut up into pot-sized chunks, adding more when needed
(infrequently). I use a liquid or paste flux with the item to be
tinned.

I have heard on this reflector recently that the amp was about to go to the
Field Testers, so unless some major problem crops up, I would expect it to
be announced as available in 4 to 6 weeks.
WARNING - I have no 'inside track' on this and I am not one of the Field
Testers for the amp
How much power in and out you looking for?
If you want an amp for something like a K1 or KX1
there's a kit called the HF Packer that works from 160-10 and
really a fine little amplifier!
It will deliver 35 watts with about 1.5-2 watts of drive.

The KX1 doesn't have the ability to observe on-air signals when the AF
output is muted, since it uses audio-derived AGC. This means that the
scanning function has to be live -- that is, not muted, and
continuously scanning from memory 1 to memory 2. (The K2 has a

Thanks for the info guys, I will have to try straight solder no/flux. That
will probably eliminate the smoke when at temp. So am I to assume that I
must strip the emamel first, then use paste and dip (again) to tin?
