Hi Mike,

yes, the ft767gx is my allround-trc and lf-rx. it is used for ham-web 9k6 on 
70cm, high speed qsk cw on 40m (extern keyer) etc. and for receiving purposes 
on lf as well.

on lf u have to plug a 100% matched antenna. u have to measure the ant input Z
of ur 767. it is not 50 ohm (same all the other rx of other types, new or old 
ones) and it is differ from qrg to qrg ! 

u should use the attenuator with care. it produces IMs which are not heard if 
the att. is off. normally it is vice versa.

it has only a LPF from 1.9MHz down.

conc. the stability in qrg: u can`t (for example) make ARGO- or SpecLab- 
screenshots. the signal traces look like "Lämmerschwänze" (in english 
"lambtails" ?).  

u can not read exactly the rx-qrg from the 767-display. but that is neccessary 
if u want to find the emission of a announced signal (beacon) on lf or if u want 
to use the 767 as part of an exciter. In that case u have to use the 
substitution methode (reading the qrg from the display of a counter).

all reasons for my buying the ft1000mp.
