SDS100/SDS200: Scanner displays the incorrect frequency

[W1LV]

SDS100 purchased earlier this month, July. Firmware: Main 1.10.00, Sub 1.02.01. Sentinel v. 2.02

Using external GPS with Full Database ON, all others off. Works great, except for this problem

Problem: The scanner stops on a channel and displays another: verified with another radio
1. NOAA weather channel 1, 162.400 MHz, shows on the scanner as AAR Railroad chanel 039, 160.695.
2. A local ham 2M repeater output is 147.505 MHz, but the scanner reads out as 145.800 MHz, ISS Operations.

I searched the forum using, "wrong frequency displayed," without pertinent hits, so I guess this is not common. Any suggestions? I intend to upgrade the firmware and Sentinel.

Search for IFX, what you are seeing is interference from adjacent frequencies.

Thank-you, JTWalker. I will try this tomorrow and report the results.

BTW, I will be in Gettysburg soon for another visit.

It's very common and you have to use filter settings as well as IFX and also attenuator if the signal level are high enough.

Thank-you, Ubbe. I am learning about the filters and IFX now.

Update Sentenel to 2.03 and update your firmware to 1.21.00 main and 1.02.01 sub

You have to update Sentinel first
