just a question, subject to opinions...

i am looking for a simple AM air receiver/scanner.

I have a GRE PSR500 and 600 - both have what i deem "noisy" AM receive.


are there any out there that are sensitive, selective - and most importantly, not as noisy as the GRE?

I have found the Icom R20 fitted with an FM notch filter and external antenna to be an extremely sensitive and quiet AM airband receiver. For monitoring in the 118-136 range you MUST use an external FM notch filter. Without it reception is substandard. The Icom R5 with the same caveats is very good but not as flexible. For a mobile the Uniden BC-780XLT. For some reason the Icom did not perform that well mobile using either a rubber duckie or 1/4" NMO antenna.

RS PRO-136 if you can find one, AWSOME aircraft receive, sensitivity, selectivity and audio. Works better for aircraft than alot of more expensive scanners out there.

What do you mean by "noisy"?

Weaker signals on AM will sound noisier because there is a lower signal-to-noise ratio in what your receiver is able to gather. Equally weak FM signals would not capture your receiver and therefore you would hear nothing at all.

I have a GRE PSR-500, PSR-300 and a RS PRO-197 and a Discone, Diamond RH77ca and a Maldol AL-500H.
With the PRO-197 I could not hear 108 to 138 AM at all until I put a cheap RS FM trap in line, now I can hear the air band.
With the PSR-300 I can hear very well with the AL-500H. With the RH77ca I can hear but is noisy at times.
With the PSR-500, it is not as good as the 300, but is better with the AL-500H.
I am located 10 miles NW of MSP airport.
I use the 300 with the AL-500H at air shows, seems to work very well, but have nothing to compare it with.
Hope this helps.

My scanners are fed by a rooftop discone via multicoupler. On VHF, including the airband and even the lower part of the milair band, I have to use the ATTenuator to be able to hear signals.

I use a Pro-163, FT-60R ham transceiver, Pro-106. Live in a tower intensive area. Not a lot of problems. Monitor VHF/UHF frequencies. But, the FM trap is a good idea, as well as, the ATTenuator feature on scanners.
Different antennas make a difference also. Some that are closer in frequency to what you want to hear will bring in a weaker signal.
