Anyone using this solder station?

[Rob Lundahl]

I recently found a solder station on eBay. This is the link.
Has anyone tried one of these?

I just performed the 2.4 KHz bandwidth mod. While the audio response is
better the output power is only 80-85 watts on SSB on normal voice peaks
with ssba set to 2 and ssbc set to 2. If  I whistle loudly into the mic I
can get 100 watts out. On cw the radio puts out 100w or more on all bands.
This was not expected as the new filter should have less loss? Any ideas on
how I can get the SSB output up to 100 watts

Rob,

When you can get a Hakko 936 for only a couple bucks more, I would not
bother with that one.  The ad looks like a lot of advertizing hype to
me, which usually means there is not a lot of substance in the product.

Check out www.hmcelectronics.com for one good source of the Hakko 936 -
it is the best soldering station that I have used, but some folks will
argue that the Weller is their choice - both are good, and you can get
tips and parts for a long time after the purchase.

Gregg,

There should be no direct relationship between doing the bandwidth
change and lowered SSB output.  You may want to check for something that
you inadvertently did.

What are you using to measure the peak power output?  What did this same
instrument read before you installed the new capacitors?

The best instrument I know of to check the peak power output is a
'scope.  It can indicate the instantaneous RF voltage easily and it is
easy to compare that level to a CW reference level.  'Peak indicating'
wattmeters do have a time constant to indicate the peak and can be
fooled by the audio waveform.  In other words, they are not always
correct when indicating the peak output of a SSB signal.

Try increasing your compression to 3:1 or even 4:1 and see if that makes
a difference.

Lastly, put the K2 display in ALC and see if any bars illuminate on the
right side of the bargraph - if even one bar lights, you are driving the
K2 adequately with the mic.
