The badgers are making cheeping noises and casting mean
looks my way, but no power on yet...
Zounds Jeeves, whats taking so long???
Finished the installed parts and circuit verification. Nothing new to
report... Could actually read the markings on all but a couple of the parts...
Amazing... Doesn't look to me like any of the parts are wrong... Maybe
the number of turns on a couple of the toroids....
Been dwaddling, putting off tampering with those toroids, but two of them need
work I think. The VFO toroid has a 1 inch or so extra length of wire on it, and
the input toroid (did I mention #32 wire??) is awfully loose so here we go. And
of course the one with the incorrect connections to the board(l8)....
Did I mention that in addition to being green on toroids, they're not my
favorite weenies???
Fired up the ugly xtal test osc and measured all the xtals in sight. Boy, if the
TS-450 just had a 1 hz readout.... Fire up the osc, key the sidetone on the
rig and tune for zero beat... Can really hear the audio zero beat clearly...
Can get down to real ZERO beat.... Neat.... Of course with the TS-450 only
reading out to 10 hz it leaves a little to be desired....
Anybody have a mod for the TS-450 to give a 1 hz readout???? :-) (Best
test instrument in the shack!!)
Found that the RadioKit schematic corrected two errors that appeared in the
CQ Sep 90 article:
The 2N3906 in the key ckt had the arrow on the wrong element.
The driver collector tank was shown as a tapped coil instead of a bifilar
coil. (This from the previous QRP 20 article probably).
Both are fixed in the Radiokit diagram...
Got a note from Rich Wilkerson, WD6FDD, Santee, Ca. Said he built
one of these rigs and it worked right off the bat! He likes it...
Well Virginia, maybe there's hope yet...
Kids, Grandkids and pizza and wine now , so no more work tonight...
Oh yes, The 'Data Book for Homebrewers and QRPers' by Paul Harden, NA5N
came today and I thumbed through it. Wow talk about timely...Started reading
the section 'QRP RIGS - CIRCUIT ANALYSIS". I may learn enough to nail this
Mutha by saturday yet!!! Looks like everyone using a soldering iron should not
be without one... And you NC38s people, there's a special offer in the instruction
sheets for you...(No I'm not affiliated with, and do not receive blah... blah... blah..
Just looks like good stuff!!
After pizza and wine I'm going to finish that section if I don't fall asleep...
Lets see... If I get this working by Saturday (end of day seven) do I get to
use it for FYBO????? Hmmmmm...
Later
