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

[satya@xxxxxxxxxxxx]

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... :-).
