While the PTO does need service at times. I have had to go in and push IC's
into sockets and clean/reset plugs into sockets. Since this is NOT a
synthesized rig there is no
clock just crystal oscillators and the PTO. I once had an

It is not necessary to use high altitude solder for altitudes
under 25,000 meters. One can merely use etheral flux with
standard 60/40 rosin core. Above 25,000 meter the solar
flux dilutes the etheral flux and so high altitude solder IS
required.

Hi Don,
As others have advised, winding the transformer is not as easy as it sounds and
a ready-made one will do the job. I think you should be more concerned with
preventing RF noise on the AC line from getting into your power supply and
hence into the Grundig radio. Here is where toroid
Gazooks! This rig has everything! No, wait, there is no crockpot for chili.
Maybe it will be part of the extra $3000 worth of add-ons.

Yes, I know that I am bordering on insanity, but hey I want to really take my
time and stretch out the building. Besides the more I learn about my K2 in the
process the better.
My suggestion would be to install one component a day. That would sure take a
lot of time.
Since knobs for the K2 and what brand of solder to use with the K2 seem to be
unending topics on the reflector, I wonder if anyone has bothered to relate the
brand of replacement knob and the brand of solder? Should Kester 44 be used
with a FT100 knob or is Ersin Multicore a good choice for
One would think that clockwise for a pot would always be the same. A clock

Surely some out there have read Philip Jose Farmer's River World series.
Mark Twain ran his Fabulous Riverboat from an ultracapacitor.

You have one or more bad connections. In the SB and HW series of Heath
transceivers the bandswitches have contacts on both sides of the switch wafers.
The two sides are wedged together and the connection becomes intermittent
with time. This causes the lower level and driver stages to drop
The easiest to get and a very excellent solvent for rosin on PCB is
Everclear (ethanol 95%) which is available at any liquor store. A pint will
last a long time (unless you quench your thirst with it). It has the
advantage of dissolving old rosin as well as that from newly soldered
joints.
I recently built an AA-908 Antenna Analyst which is a SMD-based kit. I have
been in electronics since age 14 and have built hundreds of kits of all types
including a K2 (#1107) with 100 watt amp. DSP, KSB, NB, 160 meter and various
mods. This was my first SMD kit and while I had no particular

You must have a circuit problem, either there is a bad component, or a
component in the wrong place, a bad solder joint or something in the oscillator
is drawing too much current.
Check U2 for 1.22 volts. Make sure R9 is correct value. Check voltage at the
junction of R10 and R11 should
