No more updates really
Gateway up in England working fine now.
The pre-production testers are on hold at moment.
We got a updated interface board to test.
A onsite phase shift qrm noise floor remover being looked at.
Vehicle VoIP rf gateway box too look at some point.
Other life priorities need to be finished,so put project on hold for now.
Once we got green light get back onto it
Hopefully by 2024 they'll be more new CB radios having ctcss function.
As we finding test site suffers variable noise floors day and night lifts Squelch on gateway.
I'd prefer we go full ctcss and problem goes away ,but till more CB users start using ctcss
Locally near gateway ,have to stay on CSQ for now.
TSQ is the way forward,we have conducts ctcss tests on cb band and to be far it's a game changer no qrm heard,no noise bursts ,no foreign traffic so as a VoIP base ctcss is ultimately way to do it on VoIP.
Well keep you posted 73's

lATEST UPDATES
Finalised pcb with latest UKCA CE RoHs logos,it should now support Dual-Mode Voip gateway and Repeater mode via 2- softwares used(W.I.P)
Awaiting new workshop to go ahead so can start building new base racks prob mid year 2024.
Meanwell 12Amp 13.2V DC SMP is clean for radio uses and includes AC lime EMI filter EU\UK approved Certified in a 2U rack case.
24bit sound card USB C with phone app connectivity tested.
Mini PC tested for power ratings and performance tests completed.
New APC UPS backup AC power testing to be checked.
Base antenna,mast height optimisation height for LOS use & feeder systems completed tests
CTCSS+FM testing on going with mobiles and HTs ,looks good so far channels lot quieter using sub tones system.
NEW Radios 2024 will also be tested on system either as a base radio or a mobile unit once available for burn testing purposes.
Keep you updated 73's

Re: CB RoIP?
PCB Radio Interface going through some updates currently.
New CB radios out now like radioddity cb-500,President George 2,Ares II ctcss in them including split sub tones.
So that's good news more ctcss enabled radios the better.
Been testing some new mini pc win 11 see what duty cycles and power rating as required low power consumption.
See how they work out for fixed bases.
PSU seem nice and clean and radio friendly so that's a pass
Cb-500 hook up tests next on radio interface cards
