We use diodes in series to reduce the charge side. We use a large diode on the load for protection. thp Ken wrote: Hi, I would like to know if there is some way to reduce the voltage on the MSF5000 power supply. The unit I have show's 15.5v output I would like to drop it to around

hey, I see where there is a fixed base repeater and mobile repeater difference. What are the limits on the mobile. If I have like a mobile repeater can I loan to Emeregency Services Units for like a search/resuce scene? thanks --- Jim B. [EMAIL PROTECTED] wrote: Eric Lemmon wrote:

silicone rectifier diodes will drop the voltage i was thinking 6 tens of a volt each with diode s you can feed the radio the 15.5 and wane the power go's out the battery voltage will take over even if its a volt or two lower relays can be used too ken kb9yku At 07:17 AM 7/12/2004, Ken

You first want to check the circuit diagram to see if a paralleled external voltage source (your battery bank) doesn't cause regulator backfeed problems in the base/repeater power supply regulator section. Shunt regulators as found in some Motorhead base repeater power supplies (ie

I'm using a Motorla Maxtrac for a 2 meter remote base, currently running 40 watts. I have a PA from a Mastr II cont. duty base, that only needs .5 watt for 110 watt output. Anyone know of an easy way to drop the power down on the Maxtrac? These radios wont really go down below 10 watts, and
