Transmitting in digital on UHFCB
Transmitting in digital on UHFCB
I think the answer is going to be a NO but I could not find any information on the net leading to whether you can transmit in digital mode on UHFCB band.
This band is still analogue only?
Thanks, John.

Re: Transmitting in digital on UHFCB
The UHFCB Band is still analogue only - F3E (Frequency Modulation) or G3E (Phase Modulation), and there is even a page on the ACMA Site stating that modes such as APRS are NOT allowed.freqwaves wrote:I think the answer is going to be a NO but I could not find any information on the net leading to whether you can transmit in digital mode on UHFCB band.

Re: Transmitting in digital on UHFCB
I know it's not 'in the spirit' of the definition but I do occasionally use P25 on UHFCB channels 22 & 23, they're supposed to be reserved for data transmissions only.
(P25 is data right? )

Re: Transmitting in digital on UHFCB
Thanks guys,
We have a lot of customers using UHFCB because it's a free license band but as more get interested in going digital we will have to recommend they apply for a commercial frequency license. Also applying for some commercial frequency licenses ourselves which we can rent out to customers.

Data, as in telemetry and telecommand, technically with a duty cycle of up to 10 seconds in 60 minutes - that must make for some very, very interesting (and quick!)

Re: Transmitting in digital on UHFCB
Oh well, I figure the fine for not complying with the terms of a class licence is probably less than the fine for transmitting on an unlicenced frequency assignment?
Re: Transmitting in digital on UHFCB
If no interference is caused I'd image the chances of any Anthority becoming involved, and therefore any fine being issued, are so slim it would hardly be worth a concern.
