This is a very interesting video and your presentation was excellent. Its very clear you know your subject matter extremely well. Many thanks 73 David, M0XLS
I have a question. I built a P25 simulcast scanner for our state public safety network. Early on in the build I detected that multipath was completely destroying the audio causing everything to be garbled. There was only one solution to the issue and it was to have a 800-900mhz yagi pointed to the nearest simulcast tower. This instantly resolved the issue. Wouldnt people using the same simulcast network run into issues while inbetween towers and getting multipath signals which screw up the digital signal for the client (receiving) radios?
Sorry I wrote this while watching. You did mention multipath. I still see this as the biggest problem because its a guaranteed issue unless the the repeaters were setup in a very large regional distance between then. What would be your suggestion solution for this?
Multipathing at 800 MHz will be much worse than 440 MHz, or 146 MHz than we use. The solution would be to position your antennas at your transmitters to avoid as much overlap as possible through direct paths... and perhaps lower output power.
@@HamRadioDX I posted a long comment about our use of SVXlink, how that does the voter, and a hint how you could do that in your system maybe replacing the hardware solution (boards). That comment was on the video for several hours during your nighttime and then when I looked the next day it was gone. There was no link in it. Normally when UA-cam removes comments it considers spam or abusive or similar, it just hides them for everyone except the original poster, to not alert them (shadow banning). But in this case the comment disappeared entirely, also for me, and that signals a deletion by the channel owner.

Very useful info about voting and simulcast through allstar
Glad it was helpful!
Brilliant work! Well done to all the team involved to make the "simulcast magic" happen.
Look forward to seeing how it progresses from here.
I want to be in your ham radio club!!! 😁😁😁👍📻

Thanks David, glad you enjoyed it
Do you have any videos showing an azimuthal map centered in Australia for world communications?

Can you share some links as to where to buy this stuff?
With this network you don’t need a radio. Just use the internet as normal, right?
What the heck is a Kerchunk?
Kerchunk refers to keying up the repeater without giving an ID
Why do you delete my comment?
Unsubscribed!
I didn’t delete any comment? Did you post a link? UA-cam blocks some comments that look like spam
