Hakko 808 wanted

Robert McGwier
Surely there is one person out there who has decided they can live without
that
Hakko 808 and want to give it up to yours truly?  I am not trying to save
much,
but if I give up any more coffee to save pennies, I will never be awake
again.

Hi

Sorry, my 808 is worth twice the price I paid for it. It's that good. <G>

I just did a quick google and came up with $159.95 at Kiesub Electronics
in Las Vegas - http://www.kiesub.com/hakko808.htm - $40 less then the 3
or 4 other places I checked.

Having been saying that I really need to get a desoldering station for
far too long - I ordered one.

Never! Once you've used one, you'd never sell unless slipping into the
inability to use anymore.  I now have both the desoldering gun and the
soldering station... thanks to Tom Hammond's recommendations.  After nearly
45 years of soldering, etc., and a lot of building, these are more important
than most other simple possessions.

DSP problem

Rich McCabe
In reply to this post by Tom Hammond-3
Well the newest K2 is done, SSB model, NB and 160 filter. Think I will take
a break for a couple days before I start the 100 watt PA. Just finished the
DSP and when I installed it I have NO audio at all.

I turned the RTC on and not a thing. I plugged in the audio filter and it
works fine.

I checked my solder joints and placement/orientation and all is good.

I would assume these things are hard to diagnose.

The WSL looks really nice, and I'll bet it's every bit as good as the Hakko
936-series. The Hakko probably sells for a bit less...usually around   $85
for their ESD-protected station, but the Hakko doesn't have digital temp
readout either... the good thing is that 90% of us don't need that degree
of accuracy either... thank goodness.

What most folks REALLY are liking is the Hakko 808 DEsoldering gun, which
is really the berries... you can desolder an 18-pin IC and often have it
literally FALL out onto the desktop once the last pin's been cleared of
solder. It's also great for tinning toroidal inductor leads... a nice side
benefit.

I GIVE UP!

I ordered a new one today from one of the many recommendations
that were in the $150 range.  I chose the one that together with
shipping was $1 less than the one above it after someone told me
they had one from there.

THANKS to all the responders.  I agree.  I have coveted one since I
used one to great avail at Gerald Youngblood's house on a 2 meter
transverter we were trying not to destroy!

            That's what I thought I would do  -  a year later the KPA100
came on.  Too much fun had buzzing around the "big guns" on the low end of
40m with the K2 barefoot !!

Bear in mind that the Hakko 808 is a DEsoldering
station, not a soldering station.  It is WAY
better than the manual "solder-suckers" out there;
you just have to be willing to cough up the bucks.

Why certainly.  It's disgustingly easy...

I don't recall who first posted it here (maybe Don Brown), but here goes:

1) Wind the toroidal inductor and space the turns out
    as required. Cut the leads to about 3/4" long (max.).

2) Take each of the toroidal inductor leads and bend
    them STRAIGHT OUT from the body of the core.. like
    wings. This will allow you to tin the lead almost
    right up to the body of the core, which ensures that
    when you install the inductor, you don't pull any
    of the enameled lead down into the plated-thru hole,
    possibly creating a poorly soldered connection.

3) With the Hakko 808 desoldering tool hot and ready to
    play, melt some solder into the nozzle and then slowly
    (1-2 seconds) insert the inductor lead all the way up
    to the turns on the inductor.

    In about 1-2 seconds (max.) the enamel will begin to
    bubble up and smoke.

4) HOLD the trigger (sucking the solder out of the nozzle)
    and slowly remove the inductor lead. This should leave
    you with a perfectly tinned inductor lead.

If there's any burnt enamel remaining on the wire, and this is NOT unusual,
it can usually be broken off the wire with a thumbnail as the wire is
pulled between the thumb and forefinger.

When the leads are again folded back against the body of the core, the
tinned portion of each wire should extend to (or just slightly past) the
outer edge of the core itself.

Like said, nuthin' to it!   IF you have a Hakko 808.... <G>

73,

Tom  N0SS

Geoff,

It wont take me long to do the 100Pa. Maybe have it done this weekend. I
built my first K2 last November and did the PA right away. They are just
much more handsome with the 100 watt lid on them. So will "giterdone" soon

In reply to this post by Tom Hammond-3
Thanks Tom.

This sounds fairly similar to the "solder blob" method, which I did not
find as easy as claimed - but I suppose I won't know unless I buy one
and try it out!!! :-)

I think I'll probably bite the bullet and order one.

Re: DSP problem

W2NED
In reply to this post by Rich McCabe
Rich, I had similar problems. It was in the muting circuit. The Q7
transistor collector leakage current was too high keeping the FETs turned off.

As a test, solder a wire to the Q7 collector and see where it is sitting
when the circuit is powered on. It needs to be at 5V for the FETs to be on.
If the voltage is less than 5 volts, place a 10K ohm resistor in parallel
with R14 ( 1 meg). This should bias the FETs on when Q7 is off. Also, make
sure that C8 is not shorted by solder.

Good luck...

original message:

Well the newest K2 is done, SSB model, NB and 160 filter. Think I will take
a break for a couple days before I start the 100 watt PA. Just finished the
DSP and when I installed it I have NO audio at all.

I turned the RTC on and not a thing. I plugged in the audio filter and it
works fine.

I checked my solder joints and placement/orientation and all is good.

I would assume these things are hard to diagnose.

Re: Hakko 808 wanted

In reply to this post by Brian Mury-3
Hi Bryan:

It bears NO similarity, other than the fact that the solder's heating the
enamel and causing it to melt.

This method takes about 3-4 seconds to accomplish while the solder-blob
method usually takes 8-10 seconds and is not nrealy as easy to accomplish,
though I still feel the solder blob method is the next best way to tin leads.

too bad you can't find someone locally to try it out... the difference is
astounding.
