Pi-star/MMDVM, hotspot config issue

I purchased a new hotspot from China, but cannot seem to get it to work the way it should. I also have a Zumspot as you will see in the video, and that was working fine when i was with Sky broadband, but now im with BT fibre. I setup the Zumspot before i got the new hotspot but never really tested it on TX, and now i have noticed that i cannot seem to get anyone to hear me on that either... SO... I think it maybe a ISP (Router) issue. "WHAT DO YOU THINK?"
Hotspot from China is set to Duplex Freq= RX 430.450.000 & TX 438.450.000 "No TX or RX"
Zumspot freq= 431.800.000 Simplex Can RX but no TX
On 431.800 Zumspot, TX will show in pi-star dashboard but no one comes back to me...
SORRY IF I SOUND LIKE AN IDIOT LOL....
