Mr 959:
If you don't talk ssb, no need to upgrade to the 955. The 655 and 955 are great sounding radios....superb, in fact. You will get a lot of bleed through. Longhair is right about the service from Stryker but in most cases, you don't ever have to talk with them. Deal with their auth svc center, Key CB. They're good.
The 955 has excellent ssb with no noticeable drift and again, the audio is great.
The 94 is in the same class for power. It will actually do more than the Stryker. The galaxy uses 1 mosfet to drive 2 mosfets to drive 4 mosfets (1x2x4). The Stryker uses ( I believe) a cobra 29 driver, 2078 class C transistor (which I thought was strange especially for the ssb model) to drive one MOSFET to drive 4 mosfets (1x1x4). The final stage gets about 65% the power input that the galaxy final stage gets, thus the lower power readings. If you're talking pep, I would say 80 watts compared to ehhh, 120 watts ssb. That sound about right duster?
For trouble free use, and a radio that can be easily worked on by a half way decent tech, get the galaxy.
But hey, half the fun is trying new stuff. Personally, is love to have an old Stryker 490 for AM. One of the best AMer's ever. Also had one of the best receives I've ever used.
