TS440S.42

For those of you attempting to use the MFJ-1270, 1270B, 1274 or the 1278
TNC along with the Kenwood TS-440 you will find that there is not
sufficient audio to drive the rig using the ACC 2 jack even with R76 on
the TNC full clockwise.  To solve the dilemma, replace R57 (550 ohm)
with a 2K ohm or greater resistor.  You might have to try higher values
if you wish to balance the mike gain with a microphone in place. The
tuning indicator on the MFJ-1278 is the best that I have seen so far,
only one LED out of 20 to watch and when properly tuned the center LED
is lit.  Each LED right or left indicated 10 cycles so determining where
a station is relative to K0KBY is very simple.  I also find that the HF
modem is superior to the AEA PM-1 that I just retired. If anyone has
other mods for the MFJ-1278 please let me know. I haven't had a chance
to try SSTV or FAX yet since I cannot locate a source for the starter
kit (yet).
