The DVAP works well with QNET gateway, mine has been running for a few years without a glitch, the same gateway also has a zumspot running, so I have VHF and UHF on the same hotspot. Now, running any of these hotspots as quasi repeaters is a bit fraught, the receivers are pretty deaf and the transmitters are pretty dirty, As well, trying to drive a PA with the 20mW is a bit tricky and it will definitely make you unpopular if you succeed. ?So, the short answer is it can be done, but why would you do it?
