[hpsdr] Need help in rotating T2 on Penelope

[Graham / KE9H]

All:

I would like to support Luis' recommendation.

ChipQuik is sold at Fry's, and most distributors.  A kit is about $11.
Includes flux, and about a foot of the low temperature solder.
(Which will last you for years.  Just don't get it mixed up with your
regular solder.  You will use about one-half inch to do the transformer
rework.)

You will also need some "solder wick."

The ChipQuik solder is a very low temperature indium solder that melts
at about 150 degrees F. ( around 70 degrees C)

Use solder wick to pick up as much of the existing solder as you can
on each lead.  Then go in with the flux and add the indium solder.

Use your iron tip to heat the leads, each a few times.  When the entire part
gets up to about 150 degrees F, it will lift off the board.

Clean up all the  indium solder with solder wick, on the board and the
transformer.

Then solder it back down with regular solder in the correct position.
