Re: [IRCA] Freedom and Fun Without a Ton

["HASCALL, DAVID CIV DFAS" <DAVID.HASCALL@xxxxxxxx>]

Gary hit the nail on the head.  Ultralights are very sensitive to RFI
from nearby external sources.  Have you guys ever DX'ed with an
ultralight and someone in the household uses a TV remote control?  The
noise emitted from that can be deafening!  Even from another room.  :) 

I found an SRF-M70 at a Goodwill over the weekend.  Put batteries in it,
FM was okay but AM was completely dead, just a constant wooshing sound.
It's going back, along with a vintage JC Penney AM only superhet set.
Loud hum on AC and completely inoperable on batteries.  Big, old set but
unbelievably only uses 2 AA batts.

73,
Dave in Indy

Hi Brett,
 
     I had the same problem here with my Sony MD  recorder and Edirol
R09 mp3 
recorder, which both emit way too much RF hash to  record weak TP's.
After 
much experimentation, I settled on the Sony  ICD-SX57 audio recorder,
which is 
a very high quality digital recorder  that is completely free of RF hash

during recording (as long as you  separate it from the radio by at least
12 
inches).  This ICD-SX57 can  record in near-CD quality stereo if
desired, and retails 
for just over $100 at  Amazon.
 
     After recording the TP's on the Ultralights, I  re-record the clips
onto 
the Edirol R09 (or any other mp3 recorder), for  downloading onto the 
computer.  The system worked great during the  DXpedition, and a couple
of mp3 clips 
are posted on the "Ultralighthotrodding"  group site at yahoo.com.
 
     RF hash is the enemy of the ultra-sensitive  hot-rodded
Ultralights, so 
I purposely avoided any computer-generated recording  program.  In fact,

Ultralight DXpeditioners would do well do avoid any  computers and the
RF hash they 
generate, since the stock antennas (or  mega-transplants) do not have
the 
shielded inputs common in table  receivers.  This motivates serious
Ultralight 
DXpeditioners to  find an RF-hash free recoding zone, if possible.
 
 

                 73,  Gary
