I am with Whistler in USA and seeking assistance to create a custom Danish bandplan for our TRX series scanner.
link

Information regarding band segments from 25Mhz to 1300Mhz with the properly assigned step size and modulation.
Additionally are custom service search functions that I wish to customize specific to Denmark if possible
Is there anyone here willing to help me with this?

I noted the Tape Plan on this site noted it is not be up to date.
In addition this did not provide step size and modulation details.

Jeg er hos Whistler i USA og søger hjælp til at lave en skræddersyet dansk bandplan til vores TRX-serie scanner.

Oplysninger om båndsegmenter fra 25Mhz til 1300Mhz med den korrekt tildelte trinstørrelse og modulering.
Derudover er brugerdefinerede søgefunktioner, som jeg ønsker at tilpasse specifikt til Danmark, hvis det er muligt
Er der nogen her, der vil hjælpe mig med dette?

Jeg bemærkede, at tapeplanen på dette websted bemærkede, at den ikke er opdateret.
Derudover gav dette ikke trinstørrelse og moduleringsdetaljer.

Thank you, I will review.

For most if this I can guess the modulation however the information I need that is not found is step size within each of these segments.

Tak, jeg vil anmelde.

For de fleste, hvis dette, kan jeg gætte moduleringen, men den information, jeg har brug for, der ikke findes, er trinstørrelsen inden for hvert af disse segmenter.

Is there anyone on this forum that can help me 'offline" via email or PM to help me with the step sizes and some local service search categories with sub details

Additionally would like to know if most popular use of CB in Denmark is 40 or 80 channels and if most popular modulation is AM or FM
Lastly it is our plan to include 7 predefined Service Search functions such as Airband, Marine band, CB band, PMR446, and Amateur bands however this leaves me with 2 open service search labels of your choosing.

What would you like to see in these last 2 remaining predefined Service Search functions?
One of these available service search functions is range based containing one or more start and stop frequencies consistent with the Service Search Label. An example of a range based service search is Airband broken up into smaller ranges such as 108 to 118 / 118 to 137 / 230 to 380.

The other available service search function is channel based containing 1 to 120 channels consistent with the Service Search label. An example of a channel based search would be similar to CB where the channel number and channel frequency are listed for you to select or deselect when searching.

This is your country and I wish to learn what is important to you in a scanner so you may have a choice in what you purchase.

The ? are areas I need input from someone knowledgeable of the bandplan in Denmark.

For each of these segments I need to know the common step size associated with each such as 5, 6.25, 7.5, 8.33, 10, 12.5, 20, 25 khz

Their are a few segments that I wish to know the common modulation associated with them such as AM or FM

Each segment can have only one answer. If a segment contains both AM and FM, I need to know the one most prominently used for the bandplan search function.

When creating a scannable object, you can customize the modulation as AM, FM, or NFM based upon your specific knowledge of the transmission.

Jeg ser normalt ikke spøgelser men i disse tider med krig i ukraine så er det måske ikke smart at dele forskellige frekvenser med ukendte personer på nettet?? Bare en tanke

I do not usually see ghosts but in these times of war in ukraine then maybe it is not smart to share different frequencies with unknown people on the net ?? Just a thought

Understood your concerns and I feel for the people of Ukraine however I am not sharing frequencies, I am only discussing a Denmark bandplan. Most of the information above came from this dkscan website, I am just looking for assistance with expected step size and expected modulation to help improve the search function. Is there anyone in this forum that wishes to assist me. I would prefer to do this offline via email.

I have reviewed every document I can find on this forum and applied a few educated guesses. Would you all be so kind as to review and comment on the following Denmark bandplan summary?

28.000000 to 29.700000 10 khz/step FM
29.710000 to 49.990000 10 khz/step FM
50.000000 to 52.000000 10 khz/step FM

69.887500 to 70.512500 12.5 khz/step FM

108.000000 to 136.991670 8.33 khz/step AM
138.000000 to 143.975000 25 khz/step AM
144.000000 to 174.000000 12.5 khz/step FM

230.000000 to 380.000000 25 khz/step AM

406.100000 to 431.987500 12.5 khz/step FM
432.000000 to 438.000000 12.5 khz/step FM
438.000000 to 470.000000 6.25 khz/step FM

791.000000 to 796.987500 12.5 khz/step FM
806.000000 to 823.987500 12.5 khz/step FM
849.000000 to 868.987500 12.5 khz/step FM
894.000000 to 960.000000 12.5 khz/step FM

1240.000000 to 1300.000000 25 khz/step FM

Besides CB, Marine, and PMR446, does Denmark have any other popular channel based radios currently in use?

26.965000 to 27.405000 10 khz/step FM
Danish CB-channel 19 27,185mhz FM.

Fm-modulation is the most commonly used mode in Denmark.

Thank you for your input, I will changed the CB Search to FM modulation.


Is there anything worth listening to between 25.00MHz to 26.96MHz and is so what is the appropriate step size and modulation?

Does Denmark utilize 222 to 225MHz 1.25m Amateur band? If so will need the appropriate step size and expected modulation

In our Service Search menu, I will include reprogrammed categories for Airband, Marine band, CB, PMR446, and Amateur bands. I have room for one more service search label. Is there anything that is worthy of a search in Denmark such as Business band or Public Safety? If so I will need a label and the frequency ranges that these are commonly found.

25mhz-26.965mhz is a dead frequency range in Denmark. Of course, foreign skip CB-signals may occur but are very rare.
I do not consider it necessary to search the frequency range for voice transmissions.

In Denmark, the 1.25 meter band is not allocated to amateur radio. The frequency range 220-225 has previously been
used for medical telemetry and may still be allocated for this purpose. 225-230mhz is used for DAB radio
