Bill,

This might make good copy for the SolderSmoke Daily News:

     https://www.w4npn.net/hot-iron-searchable-compilation/

Also it should be noted that starting with issue #122 W4NPN, Frank
Barnes is editing Hot Iron with help from the former editor G6NGR, Peter
Thornton. See: https://www.w4npn.net/hot-iron-directory/

I view the Daily News frequently, and also use the topics index on the
left when seeking more info on a subject. It often helps.

"Hot Iron" #100 -- Thanks Tim Walford!

Tim Walford, G3PCJ has put out issue #100 of Hot Iron, the Journal of the Constructors Club.  That my friends is a long time publishing a quarterly.  25 years!   And it is a wonderful publication, filled with ideas and inspiration.  

Tim tells us in #100 that he is passing the baton (the Hot Iron?) to Peter Thornton, G6NGR who will keep the iron hot from here on out.   Peter is looking for contributions for issue #101.  Please try to help him out.  

Thanks again to Tim.  Good luck with the farm and the house moves.  

"Hot Iron" New Issue, Great Articles

I was very pleased to find Tim Walford's "Hot Iron" journal in my e-mail this morning.  Lots of great articles in this edition, including one by a fellow we know:  Pete Juliano!  Pete writes about our esteemed dual gate MOSFETS.  All hail the 40673!  There is also a nice article about superhet receivers using a 6 MHz IF and a very convenient analog LC (yea!) oscillator arrangement.  Another discusses how to use Huff and Puff stabilizers to take care of VFO drift. N4HAY describes his initial foray into the world of homebrewing and how EMRFD helped him.

Hot Iron is free.  Tim writes:

Thanks Tim!
