Many of you have have been submitting their questions and today I am answering some of them. This month I answer: What GPS should be used on the SDS100 & SDS200 Why is my USB hub transmitting? Why can't I unlock banks on my PRO-2055? Should I trade in my BCD436HP for an SDS100? Does it look like a SDS100 or SDS200 will be required to monitor the Alameda County Trunk System in California?   If you have a question about scanning, please visit www.scannerschool.com/ask and leave us a message via SpeakPipe or the local number on our website.   We'll play your message on next month's #AskScannerSchool   All session notes can be found on our website at www.scannerschool.com/session107   A big THANK YOU to our continued Patreon Supporters.  You can support us on Patreon by clicking here.
