I have only seen this on one frequency so far. Local airport AWOS is 118.175. I normally have any AWOS or ASOS frequencies locked out for scanning. When scanning or sitting on 118.175, the beginning of the AWOS broadcast volume is very low with an obviously incorrect RSSI -60dBm. After about 3 seconds, the volume goes way up to what I would expect monitoring the AWOS and the RSSI reads around -110dBm which is what I would expect compared to other radios I monitor that AWOS with from home. Modulation is set to AM and Audio option set for Analog. I tried all the filters, but the behavior did not change. If I turn off filters, the issue goes away, but the RSSI drops to about -120dBm. No other transmissions on other aviation frequencies exhibit this behavior and there are plenty with low RSSI near -110dBm, so it doesn't seem to be associated with weak signals. I can still receive the AWOS with no filter, but it is of course much weaker and not to the level received by my BCD395XT or BCD325P2. All with the same external antenna. No other radios I have exhibit this behavior receiving the local AWOS including my Yaesu FT-250A transceiver and a Radio Shack PRO-164. This is not of course a major issue, but it is a bit of an annoyance. Has anyone else observed this odd behavior? I was going to try IFX this evening, but the AWOS is apparently shut down now.
I plan to use the BCD396XT and the BCD325P2 for aviation instead of the SDS100, but it's also nice to only need to carry one scanner. The BCD396XT is likely all I will take to air shows. The SDS100 performs very well with all the digital trunked systems I monitor especially the Simulcast systems, and it performs well enough with analog channels. But, I still prefer the BCD396XT or BCD325P2 for civil and military aviation.
