Step size, direct frequency entry

[videobruce]

A question about Close Call which I got an answer here,

SO & FO what do they stand for?
A specific question about the "Direct" function from many older Realistic radios, if it was available in the SD200 or not. Stepping up or down in
5 kHz increments
A frequency display (or what ever the spacing of the band you are in) in place of a System or Directory name. The 996P2 has it in the Quick Save Group. I don't now about the Programmable functions

That is actually F zero and S zero. They stand for FL Quick Key set 0 and System set 0. You will see F1/S1 for set 1, F2/S2 for set 2, Etc.

If you press the FUNC butting it will show D0 (Department Quick Key set 0)

The step size is settable in your bandplan settings.

Regarding the step size, can it be scanned when from the frequency tuned to? In other words, take 160.80, can I move the frequency to 160.85 or 160.75 without programing another frequency in the group?

 

[JoeBearcat]

If your step size in your bandplan is set to 5 kHz, yes.

 

[videobruce]

But what control do you use to advance or or go backwards?

 

[RoninJoliet]

You can't but you can create a "search of 160.00-161.00 and use the tuning knob to advance it in manual

Joe has already given you the answer on the 5kz steps.

Rather than creating a search, as Ron suggested, try this instead:

While scanning, press the Hold key.
Next, enter your frequency (160.80 in your example) including the decimal point.
Now, press Hold again.
The scanner is now stopped on 160.80, and you'll also see "Quick Search" on the display.
You can then use the scroll know to step up or down from the entered frequency. When done, press the Scan key to resume.

If, instead of hitting 'Hold' after entering your frequency, you hit E/enter, the scanner would think you were wanting to add a frequency, and then ask where you wanted that frequency to go.

 

[videobruce]

I'll try that.

I have always entered a freq and hit enter, and faced several choices I didn't want... I never know you could do Hold/freq/Hold to do that! Thanks Steve!

Is there any way just to stop on a already entered freq. in question and do a 'scan' there instead of re-typing the existing freq. again?

Are you referring to one already programmed, but not in the system the scanner is currently focused on?

If you hit the hold button while scanning, then you can scroll through already programmed systems & channels, but depending on how many systems & channels (trunked and conventional systems), it might take a while to get to the one you are want if using a scanner such as the 996P2 or 325P2. On the database scanners (x36HP or SDS series), you can can use the keys to hold on the system where your frequency resides, then also hold on the department to reduce the channels to focus on before hitting the channel hold key and scrolling there. However, even if you found & stopped on the desired frequency, it would not let you scroll up or down from that frequency specifically. Instead, you would be scrolling up or down in the frequencies you already have programmed,

Overall, it likely would be much easier and faster to use the Hold->Enter Frequency->Hold to focus on a frequency as a starting point of a Quick Search.

If you are using ProScan, and have your scanner connected to your PC for logging and virtual control, you can use the Frequency Tune part of the Scanner Control shortcuts to enter your frequency there, which serves the same purpose of the Hold->Enter Frequency->Hold keystroke sequence.

 

[videobruce]

Yes, programmed and stopped on that channel.

So it's
Hold, enter Freq., Hold, then use the function dial to tune up or down from there?

If that’s what you’re referring to, then no, the scanner cannot do that. If you pressed ‘Hold’, then tried to scroll up or down, the scanner will scroll but only among what you have programmed. There’s no way to make it start a ‘quick search’ using the frequency you are holding at as the starting point.

 

[videobruce]

I think we have a communication error;
I just did a 'Hold - enter Freq. - Hold' then rotated the function knob one step up, then back to center freq. then rotated it down one step. It works !
This is only a manual step scan/search (whichever you want to call it).

Again, the reason for all of this is to track down adjacent channel/frequency interference.

Good luck with that. Interferences can come from a frequency 1,7MHz away and are only 20dB lower in strength. I used a SDS100 that has the same receiver as SDS200 and generated a -60dBm signal at 825.000MHz and it is received at a -80dBm level at 823.300MHz. It will depend mostly of filter settings and IFX what exact frequency that interfer.
