Is there somewhere that describes in better detail some of the display setting in detail mode. RSSI: What are good and bad numbers? Noise: Good numbers. Working on adjusting filters and wondering what good readings are for some of these.
Thank you for the info. I am using it as a base. I use my 436HP for a mobile unitAlso of note. Your title says SDS200.
Are you using it as a base or mobile radio?
If mobile, don't get bogged down on filters and IFX.
Both of these are to mitigate (fix) a situation in a specific RF environment (stationary).
They can actually be detrimental in a mobile environment.
When mobile, your RF environment changes as you move about and filter = normal or even off is probably best.
Of course, there are very specific situations where (possible) interference is coming from the vehicle itself, that is another matter.....
It's the I/Q demodulator that takes care of simulcast issues. Filters are used to handle interference from adjacent, and not so adjacent, frequencies. That filter have a 10Mhz window that pass all frequencies to the rest of the receiver. Different filter settings move that 10MHz window either up in frequency or down and in different amounts of MHz. The window will always be 10MHz wide so the trick are to find a spot +/-10MHz from your monitored frequency where there are no strong transmitters. If you are lucky to have no other transmitters interfering, and those could interfere if you receive them in a normal way at a -80dBm strength, then you can set the filter to Off which means you are monitoring using the center of the 10MHz wide filter.At home, where a filter setting could be beneficial, I am fortunate to not suffer from simulcast and therefore have no need for filters.
Uniden are not wrong in that statement, as filter settings can help with all kinds of RF receive issues, but are not specific to a simulcast system. If a simulcast system has another frequency in its own system or anyone elses that interfere, then changing filter settings might help.I don’t doubt your explanation of how the filters work but are you saying filters don’t help when simulcast is the problem? True, Uniden never was any good telling us much of anything but didn’t they say the various filter settings could help with simulcast issues?
