Advice: frequency input and scanner

[dc8-63]

Hi,
Does anyone know if it makes any difference to the speed of the scan if you enter frequencies into a bank in sequence, i.e. (in VHF/AM) 120.5, 121.6, 124.7 rather than mixing them up.
As an extreme example, does it slow the scan if you input, say, 120.5Mhz in AM on channel 1 followed by 13.865 Mhz in ssb on channel 2 and so on.

nothing that would be noticable

The scan rate can drop slightly if the channels are mixed up over various bands.
The reason is that the scanner has to switch the front-end and vco circuitry rapidly.
If you had all the airband channels in frequency order in one bank, then UHF channels on another bank and HF on its own bank (in freq. order), you would find the scanner would be marginally faster as the transition between channels wouldn't be so great.

Depends on the scanner.

On some older scanners, which had distinctly different front ends for each band, it could be quite noticeable.

From my own experience with an AOR Comms receiver, UHF or VHF frequencies programmed randomly would not slow down the scanning rate to any noticeable degree, however, if you place a SSBHF frequency in a memory slot, it is better that it is in a bank among its own kind as if you squelch the signal, you may find it will be passed over even when transmitting.

If you wish to monitor AIR on USBHF you really need a different technique from UHF/VHF. With USBHF you have more chance of hearing air movements by sitting on a frequency with the squelch gate open and be patient, or hook it up to a tape player. most shortwave voice traffic is monitored this way with a dedicated shortwave radio receiver rather than a scanner see photo below of my Sangean TS 909 SWRX.on the left of the picture.

I like the scanner on the top shelf
