[ICOM] I did not do a good job on my 706 and AH-4 question

[D C *Mac* Macdonald]

Okay, if what you are wanting is a way to
get lower SWR on 12 & 17, you can use any
of several dozen  MANUAL  tuners to do the
job.  At 100 Watts, you certainly don't need
a monster tuner to feed either your 80m
dipole or the TH7.  They would only need one
setting for each of those bands.  Just switch
to bypass when using on 17/12.  By the way,
with the tuner and 80m dipole, you should
also do fine on 30m.

I use an IC-746 with a dipole approximately 110
feet in length.  The internal tuner of the 746
works fine on all bands except 80/75.  There,
I switch in a Ten-Tec 238 which is an L network
matcher.  It will operate with the capacitor either
across the input or the output.  It is xtremely
versatile and can hadle 2 kW.  Overkill, of course,
but I bought it for less than what a new 200 W
tuner would cost.

Let me try this again.

I am not trying to determine which ant to buy.

I use now a perfectly good TH7 (yes 3 bands) and a perfectly good 80 m
dipole and my present radio (1000MP) is a good radio and I work almost all I 
  hear
on 20,15 and 10.

I picked up a 706 MKIIG at lower than the old price so now have another
radio. With my MP and TH7 I had almost no success wkg 12 and 17. Maybe the
internal built in tuner on the MP does not like the TH7 on 12 and 17 only. 
It  loves
20,15 and 10, only.

My q was .. if I get the ICOM tuner, AH-4 and use it with my new 706 and my
SUPERB (on 20,15,10) TH7 or the 80m dipole (also superb) should I expect 
that
I  could hear/work more DX on 12 and 17 ?

The MP just does not like to play on 12 and 17 with my present TH7.

Any better ?
