Hi Mike,
The IC-9700 to my knowledge cannot tune to 137 MHz.
For APT reception a lot of hams use RTL2832U "RTL-SDR" USB dongles; They are relatively inexpensive and open up almost the entire sub-GHz radio spectrum.
Here are two I've used personally and can recommend: https://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/ https://www.nooelec.com/store/sdr/sdr-receivers/nesdr-smart-sdr.html
For a hardware radio you will want to find one with a FM BW of about 40-50 kHz to capture the signal. I've never used a hardware receiver for APT so unfortunately I cannot recommend any.
All the best, John A KE0NEV

I was wondering if the IC-9700 will tune out of band to the NOAA satellites around 137Mhz. And if so can the band with be opened up wide enough for proper reception.
