Customize Spectrum Sweeper?

[bcradio]

Hello Folks!

Is there a way to customize the frequency range that Spectrum Sweeper scans? I am interested in items int he 139-144 and 148-156 range, but don't really want the radio to be stopping on the ol' 2 metre ham bands.

I looked through the manual, but didn't find much of anything there.

Thanks in advance!

When using the Sweeper Band/All Bands mode (Func+SCAN), you can select the band segment you want to turn on or off by pressing the associated number. If you press the number, it will briefly display the band segment. On the PSR500/600 the 2 band has the VHF amateur band, but also includes 137-144 and 147-174. If you select F2 spcl and see SPCL, you can lock-out 5 frequencies in the sweeper band and it will then ignore the entire 1MHz bandwidth in the frequency range of the locked out frequencies. This is as close to a custom search range as your going to get with Spectrum Sweeper. On the PSR300/400 the only choice is to turn the band segment on or off, however after five lockouts it will ignore the 1MHz bandwidth that the 5 frequencies occupy. Keep in mind if you just lockout 1-4 frequencies, the nearby "spur" frequencies on either side of the locked out frequency will still be checked and will somewhat slow the sweep down somewhat, so it's best to loose the whole 1MHz segment as far as the sweep speed goes.

And is that "5" the SpclSweepLmt that that can be upped to "20"? Does that slow it down a lot if there are too many lockouts?

 

[DaveIN]

The slowdown results from one to five frequencies being locked out, once you lock out five, the radio skips the 1MHz segment. If you have less than five locked out in that segment, the sweep is slowed down to look at the frequencies near the ones on either side of the locked out signal, if the signal is strong enough close to the original frequency. So if the limit is increased more of the segment frequency bandwidth will be skipped.
