[TenTec] Switching speed of a Omni 6 plus

[Tim Randa <tranda@cox.net>]

Anyone know the relay switching speed of the 6+? I want to use it with a 
non TT amp that is not set up to use the tx in/out  jack on the radio. 
Is the relay output jack on the radio quick enough to run a qsk amp? I 
have the amp switching around 3ms. Has anyone built a interface box that 
can be fed with the tx in/out jacks that outputs into a rca jack for the 
amp relay?
Just looking for options
Amp is a ALS 600 with the QSK mod

Thanks in advance
