Carl: I pretty much reached the same conclusion. I ordered the Ameritron
choke from MFJ. I understand that it is a bit too long physically and needs
to be shortened a bit (the form - not the coils). We'll see. Thanks for
your note.

## I own FOUR L4B's.... and have not see this effect. Then again, I don't
run it
at 1500 w out on cw mode either. The stock L4B choke is 154uh, which is more
than plenty
for 80m [ it's triple the 50 uh used in the heath SB-220]. It also works on
17+12m.
## dunno what ga wire drake used on the choke, but it's small stuff. Watch
out,
the plate xfmr is only rated for 850va CCS.
later... Jim VE7RF
