Baofeng/Pofung Radios: A Review For The New Ham

Baofeng UV-5R

You may have run across the names Baofeng/Pofung here and there. They are a Chinese manufacturer of two-way radio equipment. What makes these radios attractive to the new ham is their low cost. If you look carefully on Amazon, you can buy a UV-5R+ dual band HT for around $40. Add a programming cable for $10, pair that with the free, open source programming software called CHIRP and you’ve got a very capable portable station.

The UV-5R+ covers 136-174 / 400-512 MHz (transmit and receive) with two power levels, 1- and 5-Watts. They also feature a dual-watch function, DCS/CTCSS encode/decode, DTMF keypad, VOX, and a handy LED flashlight. The front mounted speaker provides 1 Watt of clear audio. The audio and reception reports I’ve received were excellent. There is a two-pin, Kenwood compatible socket on the side of the radio for an optional speaker mike. An earphone-microphone is included.

One drawback to these radios is the fact that programming them manually is a bit of a challenge. However, with some practice, it is possible to program the radio without the aid of a computer. There are many YouTube videos on programming. It’s usually a good idea to learn how to program any radio in the field because your laptop/desktop computer may not be available to you in an emergency situation.

So you’ve got your new radio, you’ve charged the battery, turned it on, was greeted by the cheery voice telling you that you were in the frequency mode (yes, the radio will talk to you in English or Chinese)…now what? The first thing you should do is get CHIRP installed and running on your PC. Next, download the virgin configuration from the radio and save it to a file on your computer. That way you’ll be able to revert the radio to its factory fresh state in case you accidentally mess things up. More about CHIRP in another article.

One accessory you might want to consider is an antenna. The stock rubber antenna isn’t very good because of mismatching. You’ll find that most users recommend Nagoya antennas. These seem to be well made Taiwanese antennas that are much better than the one that came with the radio. Unfortunately, there is a rash of counterfeit Nagoyas out there so be careful. I have had good luck with the MFJ-1717S dual-band antenna. Just remember to get an antenna with a female SMA connector.

Another nuisance I’ve found is the retaining nut for the antenna connector on the radio coming loose after a couple of days use. The simple fix for this is to remove the nut and apply a small amount of thread locking compound to the threads. Tighten the nut well and that’s it. Just make sure that the thread locker is removable because there will come a time when you have to take the radio apart for servicing. I recommend Loctite Blue.

I’ve had my UV-5R+ for two years and it just runs. Last year I bought a BF-F9+V2 which is the tri-power version of the 5R+ (1/5/8 Watts). These low cost, easy to use radios will make a welcome addition to any emergency Go Box.

Join us for the ARRL Rookie Roundup SSB on April 17!!

Are you a new Ham who has received your first license in the past 3 years? Are you interested in finding out what contesting is all about?   The ARRL has a contest just for you! The ARRL Rookie Roundup SSB is coming up on Sunday, April 17 from 18:00 UTC until 23:59 UTC (2 pm – 8 pm) and it is just for “Rookies”. We will be fielding a Multi-Op entry from the AB1OC/AB1QB QTH using our club callsign, N1FD.

Non-rookies can help by getting on the air and working rookies in the contest! See the ARRL Rookie Roundup Site for the rules and exchange.

We will hold elmering sessions for the contest to help you learn how to operate our station and use a contest logger the weekend of April 9th and 10th.  Join us at one of three sessions :

  • Saturday, April 9 at 10:00 am
  • Saturday, April 9th at 2:00 pm
  • Sunday, April 10th at 1:00 pm

The rules for the Rookie Roundup are on the ARRL website at http://www.arrl.org/rookie-roundup. If you are a rookie and you are interested in operating in the contest, or just visiting our station and watching the operation, contact Anita, AB1QB at [email protected].

3D Printing for Fun and Homebrewing

I recently picked up a mini 3D printer made by M3D.com because I wanted to channel my inner-maker and see what it was like to dabble in 3D printing, but I didn’t want to spend the $1k-$2k or more for trying out something that I might not like.

This particular printer has a capability of printing objects up to 5.9″ x 5.9″ x 5.9″ in both PLA and ABS.  It is not the fastest printer out there, but with a little patience and sub $400 prices, I was willing to give it a try.

3D Printer

After unpacking the printer and settling on the white filament for my first dive into 3D printing, I looked for something that was simple, small, and easy to print.  I picked a flop-eared bunny for one of my daughters for Easter.  I pulled this 3D model from a well-stocked source of 3D models called Thingiverse.

It was easy to get the printer up-n-running.  Here is a sequence of photos during the 4-hour process with the final image being the bunny with all raft and supports removed.

Now that I got thru my first successful 3D print.  I started thinking more of what can I print that might be practical and useful?  I know I have always wanted something to keep my charging cords from falling behind a desk or nightstand, so you can print these:

And how about a nice custom case for that new Raspberry Pi you recently got?  Or custom printing some other little project box?

There are many helpful projects you can print that already exist on the Internet and many colors to choose from.  Want to strike out on your own and brew your own custom widget?  Here is a chance to learn 3D modeling and there a quite a few freeware versions of software to choose from.   I recommend going to a site like 3D Printing for Beginners for starters.  There appears to be quite a bit of info on this site to keep you busy in learning about 3D printing.
