I have a Delta Force with the PPE mod and it's a talker, I ran it side by side against a Justin tuned Magnum S3 and all the local base stations on the air picked the Delta Force hands down as the winner. (Don't panic people, there are plenty of good techs out there.)
W1R3T4P, as much as I like the PPE mod I kinda doubt it would be necessary on a Stryker radio. They seem to rock-n-roll with a good tune and alignment.
As far as the 70 watts goes, I don't know could be. The S3 I was referring to was supposed to do 51 Bird 43P watts. On a bench into a Bird 43P @ 14.2 volts all we got was 38 watts. In order to talk clear though we had to back the mic gain down a tad and this knocked the power down to about 32 watts.
