[Icom] help with qrm/qrn

Fri, 17 Jan 2003 13:44:18 -0800

Hi Hart,

	I have hearing problems from my military service. You might want to
check with MFJ manufacturing. The president of this ham supplier also =
has
had hearing problems and he built a device the company sells that works =
off
the audio output of the receiver to condition the audio for those of us =
with
imperfect hearing.

	If this doesn't do the job directly, MFJ may know of other add on
devices that can be used with less expensive older equipment that may be
helpful to you. They can be reached at www.mfjenterprises.com=20

Best wishes
Barry

Here is my problem, and I hope you can shed some light on it.

I want to get back into HF radio [phone mode] but I need to know what =
type
of rig I should be looking for. I live in the city of toronto and I =
can't
put up a dipole or beam so the only other antenna is a vertical one, due =
to
the limit space that is available to me. I have a medical problem called
tinnitus [or ringing of the ears] and after listening or trying to tune =
out
the hash or what I call the fried egg sound [after 5min of listening] I =
get
sevier headaches. So I abandoned HF all together and sold my rig.
I'm currently on 2m/70cm and I don't seem to any problems with qrm/qrn =
do in
part with the squelch on the rig. And i'm glad for that.

A few years ago I got into 20M qrp'ing and found the radio [mfj model] =
had a
built in crystal which seemed to get rid of or lesson the background =
noise.

So I figure it may not be line noise at all but just atmospheric noise. =
I
remember that the higher the freq the less the noise was. e.g. On 10M it =
was
around 1-3 S units and on 160M it was around 5-9 S units.

I need to know what type of rig or equipment I can buy that isn't going =
to
put me in the poor house or were I don't have to refinance my shorts [if =
you
know what I mean]. I ask this because when I got into ham, I made the
foolish mistake of buying what ever looked good and never even =
researched
the products. So you see I don't want to make the same mistake twice.

I am looking forward to your thoughts on this matter, and please don't =
be
afraid to ask any question that might help me. Please e-mail me off =
line;

Hart
