The FCC is actively dismissing applications for renewals and/or modification still containing a bandwidth in excess of 12.5 KHz. In its latest release the Commission threatens monetary fortifiers of up to "$16,000 for each such violation or each day of continuing violation, and up to $112,500 for any such act or failure to act.". In its public notice the FCC detailed a plan to send out electronic notification to licensees who are not in compliance. Link to story here

Thanks for the info.

Now that the agency is not dismissing applications for wideband use if "the applicant certifies that the station equipment meets the narrowband efficiency standard." So if you're filling 25 kHz with data, you can still, in theory, get a wideband license.

Q: What happens if you get a wideband license but don't always run at 5 Hz (e.g. you need max power at times but your radio can't do 5 Hz at max power without overheating)?

 

[Donald E Robinson]

Jim,
Not really sure what you mean. I am running 5Hz with my 4watt radio at maximum power (all day) and it barely get warm.

Maybe 35watts get warmer, I don't know.

Why can't you run 5Hz at 12.5KHz? I have no problem.

 

[Jim Frame]

Why can't you run 5Hz at 12.5KHz? I have no problem.

My understanding is that the modulation type required to run 12.5 kHz at 5 Hz has a shorter range than with 25 kHz. I haven't tried it, that's just what I've seen posted here.

I am in the process of obtaining my FCC license and here is some recent feedback from the licensing agent:

"The application was sent to the FCC for them to grant. The FCC has returned the application saying that the emission designators must be submitted as a narrowband emissions. I believe the one they are questioning is the 12K06G1D. We will need to list it at 11K06G1D."

and...

"The coordinator and I both thiink that the one emission designator - 12K2G1D -

is listed as a wideband and we think that is the one that the FCC is rejecting. We can list it as a narrowband emission - 11k2g1d. Or just drop that emission is another option.


Let me know what the radio guy suggests."

Jim, I have been trying to get my mine modified for some time now. I understand that the license can be modified so you are covered for all scenarios that are available with my radio 1 Hz and 5 Hz.

Now that the agency is not dismissing applications for wideband use if "the applicant certifies that the station equipment meets the narrowband efficiency standard." So if you're filling 25 kHz with data, you can still, in theory, get a wideband license.

Q: What happens if you get a wideband license but don't always run at 5 Hz (e.g. you need max power at times but your radio can't do 5 Hz at max power without overheating)?

Multiple emission designators can be listed on your license.

Field test have found that D16QAM modulation decreases the working range of the radio approximately 20% as compared to DQPSK modulation.

I need to get back to the licensing agent with regard to this. Does anyone have a strong opinion as to how I should handle this given all of this recent discussion? My current configuration is the Triumph-LS, the Triumph-2 base and the HPT435BT radio.

Thanks much,
Dave.

Dave, that is the same setup that I have. Are you by any chance using EWA as your agent. If so they should be able to reference my application.

Adam,
No, I am using:

Federal Licensing Inc
1588 Fairfield Road
Gettysburg, Pa 17325

Thanks for the reply.

Look at page 8 of the thread named 2 or 5 hz, Matt's got some info on there that might help.

I communicated with Michael Glutting at Javad today and he said for now the FCC is not allowing the 25KHz channel spacing, only the 12.5KHz. He also said they are working on this issue and to check back in a couple of months.
