Subject: ICOM RS232 INTERFACE ?
To: ham-equip@ucsd.edu
HI.
I recently purchased an IC-725 and to use it in the mobile, I would like to
build a small controller device to remotely control the rig, which would be
installed in the boot of the car.
This device would control the rig via the RS232 interface.
Questions :
The device needed which plugs into the ICOM rigs to convert it's
communications protocol to RS-232 (I can't remember what it's called) -
a) How much does it cost ?
b) Is it possible to build this device yourself ?
c) Are any software libraries available to control the rig over the RS-
232 ?
Do you know of anybody who has done something similar. Maybe you saw
something like this in a magazine ?
Thanks for any information that you may have for me.

Subject: Kenwood TS440 Power Out Control?
To: ham-equip@ucsd.edu
I own a Kenwood TS440 and am generally happy with the radio but wonder why
there is no power out control. The only thing I really set upon transmit is
the ALC control. Is this radio always at maximum power out? Do most HF rigs
have a power out control? Tnx.

Subject: Question about signal enhancers
To: ham-equip@ucsd.edu
Here's the situation:
There are two stations brodcasting on the same signal, 1520 AM.
One is from Buffalo and 50,000 watts the other is from a town outside of
Amherst, MA, not sure how strong the signal is, which is where I am. At night
and up until sunrise the station from Buffalo overpowers the other station.
So, my question is, if I buy a AM signal enhancer will it:
1. Make the Buffalo station overpower the other 24 hours a day
OR
2. Just make the station closer to me stronger
Please e-mail me your ansewer
Thanks

I'd be interested in anything you find out as I'm on the verge of the
same decision. The local dealer had a stand-up sign from Yaesu that
showed some of it's advantages over several competing units.
Unfortunately, it wasn't available on paper.
Right now I'm leaning towards the Yaesu for the following reasons:
$100 cheaper, $25 rebate currently, more channels, reduces output
power to minimum automatically to save batter power.

I own an FT-530 and I think it is a good buy for someone looking
for a new HT. The standard rubber doesn't work that great on 2M
but it seems to work well on 70cm. As far as intermod is concerned,
I live not too far from a big pager antenna farm and the 530 does very
well with intermod. Battery life is very good with the xmit save and
the rx save, I just use the wall charger and the HT lasts for hours
depending on how much you use it of course, so that might vary with
your use.
Also one of the great features I think is how easy it programs compared
to the Kenwood. I t seems the Kenwood has very few buttons and each
button has 2 or 3 functions each which can get a little bit confusing.
Hope I was of some help in making your decision. If you have any more
questions you can E-mail me at:miken@yalevm.ycc.yale.edu or
N1JJX@N4GAA.CT.USA.NA
73 and good luck
