Could someone please tell me the address of a company called IRC. I
believe it is in Florida. They carry (hopefully) CW filters for my HF
rig.

Thanks and 73,

 I've been looking at battery packs for my TH78a.... Has anyone
 used the QUANTUM battery packs? Any feedback appreciated.

To: ham-equip@ucsd.edu

I was thinking of getting a Kenwood TS-50  (the tiny HF rig).
Its main appeal for me is that it's small, and I can have
someone bring (smuggle) it to me here in Israel rather easily.

Are there any good reasons NOT to get this rig?  Is there anything
it doesn't do?  Does it have any nasty habits?  I have the QST review,
and the only bad points I remember are that it doesn't have VOX
(big deal) and it has a bit of filter blow-thru.

Oh, will it work OK for RTTY/Pactor, etc.?

  There are several companies that make what is commonly refered to as
  "disguise" antennas.These are made to take the place of the regular
   broadcast antenna,and when combined with a coupler,will also function
   as a broadcast antenna.One of the companies is Antenna Specialist Co.
   at 216-349-8400.Another,which I would reccommend,is STI-CO Industries
   at 716-662-2680.Both of these companies will sell direct or send you
   to a local distributor.One additional piece of info is that Barker
   -Williamson use to make a tuner for your purpose.I dont know if they
    are still in business.I should warn you that "disguise" antennas are
   very expensive but work fairly good.I use an antenna specialist model
   for 6 meters on my chevy and have had no problems.Good luck!

Subject: receiver sensitivity
To: ham-equip@ucsd.edu

I know in general one wants a receiver with a low sensitivity
threshold in terms of lower microvolts.

Is there a practical way I can understand the differences between
receivers of say 2, 1, .5, and .125 microvolts sensitivity? 
Obviously the factors of power of transmitted signal, distance
to source, interference, etc., all play into this.  But is there
really an effective minimum sensitivity one needs for say local
VHF repeater/simplex use versus "general" HF versus DX HF?
How do broadcast AM, FM, TV and international SW stations compare
to amateur signals in field strength and required receiver 
sensitivity?

Thanks.   73 de Kevin

                                                       ^^
Gad, what a rotten receiver that would be! Make that 20 uv (u = micro).
