Kenwood TH-F7E (TH-F6A) deaf on HF ?

Post by Igor » Mon, 22 Jul 2002 22:58:43

Hello, All,

I have one for last couple of days

It works fine both 144 and 430, but it seems the embedded 0,1 - 1200 mHz
scanner is almost useless for HF.

I can hear only few broadcasting stations below 30 mHz  with its bar and
*** antenna. No one ham station for whole weekend on 40 and 80 !

Also I have  handheld SONY ICF-SW7600GR - it works much more better on HF
with approximately same size of antenna.

May be my sample is broken and need the repair ?

Regards,
Igor

I don't believe your handheld is broken.  My TH-F6 is also virtually deaf in
the 1500 KHz-88 Mhz range along with 230 Mhz up (except for the 440 MHz
amateur band and the immediately adjacent business frequencies).  I cannot
copy WWV on any of their frequencies and I've only rarely heard  traffic in
the 20, 40 or 80 meter ham bands.  An external antenna helps but very
little.  Also my recent experience at an air show with my HT and a friend's
VX-5 was sorely disappointing.  My friend could hear aircraft several miles
away while my HT could only copy them when they were within sight.  In
addition, the RF dense environment of the air show effectively shut down my
440 MHz receive while my friend's HT was used on the same repeater with
virtually no intermod.  I am not necessarily a Yaesu fan, BTW.  I'm simply
stating my experience.  YMMV.

No it's not broken.  I've had one since Dec 2001 and it does the same thing.
Even when I put an outside ant, it
doesn't help much.   I guess it's a selling point and the end user/buyer
doesn't know that until they buy it.
