These are the ones I use.? They are nice to reassure you that the Pi and modem are getting the correct voltage.? You can check the supply voltage at the same time by pushing a button on the unit.?

Aside from the suggested supplies that others have given you might want to try one of these. I've used early models of this: https://pimodules.com/product/ups-pico-hv4-0-p-poe[1] on a dozen remote

Cort.. would you like to post the values of the caps and inductor Dan

I use the same “mini 360” regulator that RB uses on the Pi-hat STM32-DVM on my STM32-DVM-MTR2K and STM32-DVM-MASTR3 modems. Scott has had really good luck in sourcing his, but I found that often

I've got, had, 2-3 of those. After running a Pi and RA- interface for a month or two, one of them popped and smoked... tossed them. The PowerWerx USB Buddy gadgets haven't failed yet.? Still

I do have the RB DC/DC converters in use. It is working but I have not measured the ripple voltage. 73 de Veijo ti 5. tammik. 2021 klo 15.38 Alan Barrow <ml9003@...> kirjoitti:

Hi David, About 30min before I read Kevin's text, I purchased two "Car Powered Technologies" units for $13. See pic. The other ads clearly showed just the letters CPT on the label. Unfortunately, I

Hello fellow repeater- builder group members.I have a Motorola micro 220mhz repeater that I'm selling . If you have questions or would like pictures email me off the list. Thank you?

Hi Frank, I've found that the "CPT" power supplies are not all created equal. It would seem the manufacturers figure since it's hidden in potted epoxy, no one can see what was actually

Hi Kevin, On the one David suggested (board only), one of the views describes a heatsink should be installed on the chip (see pic) if the intended load would exceed 2.5 amps. Since all the info

Hi I am in need for technical data, schematic or manual for a Trygon M5C36-15 power supply manual It is a older 36 Volt 15 Amp power supply. The one I have failed with full current shown on the

The best 5V power supply I've ever found for a Pi is a lighter plug USB adapter from Amazon, the "Amazon Basics" model. Take it apart and discard the shell, solder power in and a compatible USB cable

I'd be careful about the "CPT" modules. In the description it says "Nominal current rating: 12A", but on the case of the unit it says "5V 3A". -ed, k9ew

?I've had LOTS of failures with these "CPT" units.? They are packaged very nicely, but we've seen lots of issues / failures. The ones David mentioned are way better

This is what I use: https://powerwerx.com/usbbuddy-powerpole-usb-converter-device-charger Might be a bit more expensive than ebay but sourced from a us company and comes prewired with power poles.

My MTR 2000 UHF, the power supply gets really, really hot, around 110 degrees! Any idea what would cause that????????? wrote: -- Glenn (Butch) Kanvick KE7FEL/R 1-406-655-1232
