12 VDC Power Control

 

Many amateur radio operators have equipment operating on 12 VDC power supplies. There are times that the equipment needs to quickly switch to a 12 volt battery back-up. There is a very easy way to accomplish this without any intervention needed to switch back and forth from the AC operated power supply and the battery back-up as needed. I’ve found that the PWRgate meets the need to control a supply of 12 volt power to equipment when the AC power supply fails.

You’ll see in the photo that this unit has the Anderson Powerpole® connections that make connections super easy, if you have adopted Powerpoles® as your method of 12 VDC power connectors a standard. Remember that the Powerpoles® are the standard with most ARES and RACES groups across the Country to make interoperability of powering equipment easy but that’s another topic.

The latest model of the PWRgate has three output connections for the equipment that you may need to power, up to 25 amps. There is a connection for your back-up battery to charge your battery and power your equipment when the AC power supply loses its 120 VAC supply, as well as the input from an AC powered 12 VDC supply.

I can say from experience, I have one in use, this unit works as advertised. It is great to maintain 12 VDC to equipment that may otherwise lock up if the power is removed then reapplied when an orderly shutdown/restart should be done. The PWRgate is offered by an amateur radio operator, who provides fast shipping and super service if an issue may arise. You can visit the web site http://ki0bk.no-ip.com/~pwrgate/LLPG/Site/Welcome.html for more information on the PWRgate and other devices that are available.

New Tri-Band Baofeng on the Market

 

UV5X3The Baofeng Tri-Band hand-held hits the market! For those interested in using the 220 MHz band it is now a bit easier with the new UV-5X3, 5 Watt Tri-Band Radio: 130-179.99mhz (VHF), 222-225.99mhz (1.25M), 400-520.99mhz (UHF), it also is reported to have the FM broadcast band receiver.The new hand-held looks a lot like a UV-5 but “you can’t judge a book by its cover”.

 

The best place to go for a good review of the radio is: http://www.miklor.com/COM/Review_5X3.php

Yaesu FT-991 A huge step for mankind….

Hello again

It was a while ago since I wrote anything here, but now I really have something to write about!

As maybe some of you know, I took the step, and bought a new radio, the Yaesu FT-991. It is an all band all mode transceiver incl C4FM, where all the best parts from Yaesu’s more exclusive transceivers come together in a very compact sized box. Already the first day, i was struck by the radios very quite receiver and ease of use, even though it’s the first time I’ve ever used a radio with touch screen. But, if you are familiar with a smartphone or a tablet, then you feel right at home with the FT-991. Last weekend, I got to test it’s phenomenal ability to pick out stations just above the noise, even though I had 59+ signals right beside, and without earphones, it was easy to hear what the weak station said, and, to work him! This time Yaesu really hit the head on the nail! I dare to say, that nobody in this price range come even close to the FT-991! It is a radio that will fit in any Go-Box, since it’s even got a built in tuner as well as a built in audio board for digital traffic.   Yaesu FT-991FT-991 Rear Panel

I will bring the radio to the next meeting, so you all get a chance to play a little with it. I hope we get a weather like we had today, so we can put up some antennas, and make a few contacts!

See you all at the QCARC meeting!

PS: The Yaesu FT-991 price is now even lower, $958 after mail in rebate at RandL electronics, which is a super deal!

Powerpole® Crimp Tool Review

For many hams the go-to 12 VDC connector is the Anderson Powerpole®. I feel the same, this connector is the only one that makes sense forPP crimper convenience and durability of connection among my own radios and if the need arises other power supplies. This form of 12 VDC power connection really makes the issue of interoperability for a power source a non-issue. The connector is recognized across the Country as THE power connector to use for ARES and other public service applications.

Anyway, where this is leading is the issue with installing the connectors on the wire. It really is not difficult but there is a standard, in order to interface with the rest of the world! Amateur radio has adopted the standard that when viewed from the contact side, the mnemonic for remembering the arrangement for the positive connector is: “Red Right — Tongue Top“.
Of red powerpolecourse red is positive while black is negative. Even though there is a standard, I feel it is still a good idea to confirm the connection that your rig may be connected to is verified visually and also electrically using a volt meter or one of the LED connectors that indicate if the connectors are configured to the standard.

 

The installation of the connector contacts can be problematic if the proper crimp procedure is not used. I’ve used the crimping pliers type PP crimper diescrimp tool, until now. I finally invested in a crimp tool made for the Powerpole® connector contacts. I have to say that I should have done it sooner, no exaggeration! There are are several styles of crimpers available with the special dies for the crimp, study their operation and style then decide for yourself which one suites your needs. The version that I settled on has a feature in the tool that helps maintain the alignment of the contact while the crimp in done (see photo). My opinion is that the crimp done with the pictured tool is far superior than the crimping pliers style. Along with the quality of the crimp, there is no distortion to the contact. With no distortion there is no reforming the contact which results in a much easier insertion into the Powerpole® shell and much better contact surface for maximum conductivity.
