[IRCA] Daytime testing of the Slider e100 and Crate Loop



Hello Kevin,
 
     Great work on your Crate Loop article posted on  DXer.Ca, and also on 
the fantastic daytime DX catches with your Slider E100,  assisted by the Crate 
Loop.  Those are really some outstanding catches,  even for the enhanced 
daytime conditions currently prevailing.
 
     As crammed as my tiny shack is with multiple  loopstick hot-rodding 
experiments, after reading your Crate Loop article, I  think there might just be 
space for another project  :>)     Congratulations again, and have lots of fun 
with  your little Slider DX monster this winter. 
 
     73,  Gary

Hi all:

I had a chance to try out the Slider e100 with and without  the Crate Loop
this morning to see what kind of improvement in sensitivity  and
selectivity could be had with the hottest receiver around. For  stations
that were already doing well on the “barefoot” Slider,  improvements with
the Crate Loop were often quite modest. However, with  targets that were
weak and/or suffering interference from strong locals,  the results were
often dramatic. Some examples were:

530 – the  Slider had the airport TIS station with fairly reasonable audio,
but  nothing else, since it was not that far above the noise floor. With
the  Crate Loop, the airport TIS came in clear, and the more distant TIS
station  for the mountain pass on I-90 was also intelligible above a much
quieter  noise floor.

560 – in the shadow of a very strong local on 570 (KVI,  5kw about 14 miles
away) nulled to the extent possible, the Slider had a  semi-local (KPQ)
fairly good with mostly-intelligible audio under moderate  interference. 
With the Crate Loop in adjacent orientation, the audio was  clearly
intelligible and the interference much reduced.

670 – the  Slider had KBOI (420 miles away) with fairly intelligible audio
that  occasionally dipped below intelligibility and/or disappeared during
fades.  The Crate Loop had consistent good audio that remained
intelligible during  most of the the fades.

680 – the Slider had a semi-local old-time music  station with decent
signal but suffering horribly from an image/heterodyne  from a strong local
on 1590. With the Crate Loop in adjacent orientation to  notch out 1590,
the image disappeared and the music station was in the  clear.

1060 – the Slider had nothing but interference from a nulled  strong local
on 1050 (KBLE, 5kw about 7 miles away). With the Crate Loop in  facing
orientation, CKMX in Calgary (450 miles away) had reasonable CW  music, and
the interference was noticeably reduced.

1110 – the  Slider had a 500 watt semi-local (KDWB, about 50 miles away)
with mumbling  audio. With the Crate Loop in facing orientation, the audio
was clearly  intelligible.

1140 – the Slider had CHRB (440 miles away) with mumbling  audio under
heavy interference from a nulled strong local on 1150, while  the Crate
Loop in adjacent orientation brought it in with intelligible  audio and
almost no interference.

1530 – the Slider had  KFBK-Sacramento (600 miles away) with somewhat
intelligible audio, while  the Crate Loop had clear audio.

1640 – the Slider had semi-local KDZR  with acceptable audio (if Radio
Disney programming can be referred to as  such... :-), while the audio with
Crate Loop was much better (correction:  much clearer... :-).
