1. To extend radio range you can use pie pan. FALSE 2. You have to use Snubbers if your Bus wire is long. FALSE 3. DCC track signal is AC or DC FALSE In truth it is neither one. DCC is computer data sent in PWM pulses 4. I can read DCC voltage correctly with a multi-meter FALSE only a purpose built DCC meter such as the RRampmeter or an oscilloscope will give accurate readings. You can get "close" with a regular meter set to AC. 5. larger layouts need more boosters - FALSE The number of boosters needed is based on power consumption. Factors include: How many locos are running at the SAME TIME. Do they have sound or lights? Do you run lighted passenger cars? Do you have stationary decoders on the track bus? 6. The booster with the highest current rating is the best. FALSE An oversized booster will have too much available inrush current for smaller scales. Unless you have correctly set circuit protection, locomotive damage is possible. 7. Sound Decoders take a lot more power. FALSE High inrush current is only at cold start up. While running, sound only adds 20% more power. 8. BEMF never works in a consist. FALSE It is more sensitive to mismatches of decoder/ loco / manufacturer and is difficult to setup correctly. But, it can be done. Most users do not need BEMF, and it is ok to disable if causing issues. 9. The command station will shut down when a booster shorted. Maybe If you only have one booster and no circuit breaker at all, then yes. Remember that the protection in ANY booster or Command station is only designed to protect the equipment it is part of. 10. Programming on the main / OPS mode prgramming is dangerous. False Use for specific decoder address / specific CV. Just dont use broadcast / blast mode - address 0. Remember you get NO readback of CV in POM / ops mode CV29 is different among decoders - false The four Mandatory NMRA CV's are: CV1 Primary (short) address CV7 Manufacturer version number CV8 Manufacturer ID Number CV29 Configuration Data 12. Decoders can be selected based on physical size - false 13. it's ok to run DC and DCC at the same time - false
