EF Johnson Messenger II on 10 Mtrs - Project
Some progress. Xmtr now puts out about 6 watts on 29.100kc. Tweaked tank &
by-passed R-48.
Dave - WB1EAD sent me a xtal for 29.100kc ( xmit ).
Rcvr another story. Still fiddling with the rcvr VFO. ( Continuous rcve
function )
Schematic attached if anyone has an idea of how to bring rcve up to 29.000 /
29.100kc area.
Dale - W4OP states xtals are third harmonic. Rcve xtals are less 455kc. Will
order a few from Brian.
Using xtals on rcve, should just be a matter of tweaking..... I hope.
Still would like to use the continuous rcve function though.
L-113 ( shown L-13 in schematic ), does adjust as does the trimmer C-111
attached to it, but not nearly enough.
Add / subtract capacitance?
There are two small disk caps with one side of their leads twisted together (
gimmic? ) in the VFO area.
Any help would great.
73,
Tom
