The dual 520 mod won't yield great results though. Tried it back when several of us were on cbt with help from the cbt cast, and just as Sonoma stated it won't behave like the 10 meter counterparts. There has to be something missed in order for it to work correctly, maybe in the amp chain somewhere. If I remember correctly I could only achieve between 35 to 40 pep but barely touched 40.
