Hi All at LF,

Still making improvements to the antenna system here, just installed 4
additional earth rods & this showed about 10% increase in antenna current
(can't give you an accurate current measurement at the moment as I do not
have a calibrated meter, I'm working on that as well). I have been
monitoring my own signals on Dave's (G3YXM) grabber & last night was showing
"dog boning" on my QRS3 tests, thats the strongest I've seen it. G0MRF
transmitter running at 322 watts DC input.

The biggest let down in my station is the Yaesu FT747GX which although is a
good reciever at LF the thing drifts a lot with room temperature
fluctuations even though I fitted a TCXO unit recently & although it did
make a considerable improvement to stability, on long dot lengths the signal
can almost drift off the Argo display.

I think I have finished all the DIY jobs my wife lined up for me so I hope
to get serious on 136 soon.
