I try also to receive NOAA APT transmission with an helix but i got very marginal results even with a preamp for 137khz. The signal was
better but the pagers QRM was also boosted by about a factor of 5...
The only one viable solution was to use my VHF satellite beam with a PAR electronics vhf notch filter part number 5602516. Of course you
should have a 50khz band pass below that results are also very marginal. I don't know if the PCR-100 is able to received at this bandwidth
but the PCR-1000 can and it can be driven by WXtoimg software.
P.S. My home made helix is available for 35$ plus shipping but a bit hard to securely fit inside a shipping box. pics available if needed.

I never had any luck with any of my other receivers such as my Icom R20, being to narrow for this purpose, although I know of guy's who have modified receivers successfully for just this purpose. My set up may be seen on my website: www.stormchaser.cjb.net click on: Quadrifilar Helix Antenna. The page needs to be upgraded, as I use a newer laptop than the one shown.
