Best DMR Hotspot

DMR Hotspot

DMR Hotspot

So you have decided to take the leap into Digital Mobile Radio (DMR).  DMR uses the internet as the backbone for carrying communications.  Adding an MMDVM board to a Raspberry Pi is one common way to create a hotspot.

To get to that backbone you need to enter the internet either through a DMR Repeater or through a DMR Hotspot.

A hotspot is just a gateway to the internet and your radio talks to the hotspot and then your transmission is carried through the net to someone else’s repeater or hotspot.

I’d be remiss in not pointing out that so far no radio companies have really jumped in this market.  You would think that the big dog radio manufacturers that sell DMR radios would also produce DMR Hotspots, but they really don’t.

It is mostly amateur operators who design and produce MMDVM boards and sell them to the public.  You then roll your own.  There are a couple of exceptions here as Bridgecom Systems sells pre-configured DMR Hotspots.  Also, a company called Shark RF sells a hotspot called OpenSpot.  Both are kind of pricey.

Unlocked Ham Radios

Unlocked Ham Radios

The FCC started getting serious about the importation of unlocked ham radios sometime around 2019 or so.  An unlocked radio is one that transmits on frequencies not intended for the  type of radio that it is.  For example, a GMRS radio should not be able to transmit on amateur radio frequencies and vice versa.  Some folks also refer to this as jailbreaking although that term is more synonymous with cellular phones or game consoles.

The rules regarding the importation and sale of such radios in the US is pretty clear, especially regarding any Family Radio Services such as FRS, GMRS, and MURS.

Retevis Ailunce HA1G GMRS Radio Review

Ailunce HA1G

Ailunce HA1G

Ailunce (made by Retevis?) has recently released the Retevis Ailunce HA1G GMRS radio and it sure looks like a contender.   There is no shortage of GMRS hand held radios out there.  Many of those offerings are inexpensive, as well.   So you need some standout features to compete in this marketplace.  For me the stand out features are its Ingress Protection level (IP67) which is a waterproof rating.  Essentially, that means you can get caught in a wicked rainstorm while hiking and not worry about your comms.  The Ailunce HA1G also has an interesting screen layout and menu system.

Another huge plus is that it is ready to roll right out of the box.  All 22 GMRS channels are programmed in along with the 8 repeater channels.  Programming from the radio itself is fairly easy and most users wouldn’t need to connect to the Customer Programming Software (CPS).

Before You Buy Any Radio

Before you purchase get the FCC ID number of the radio and run it through the FCCID website.  Here is the data for the HA1G.  All of the technical data and testing reports are available to download and view in addition to product manuals, photos, etc.

DO YOUR HOMEWORK FIRST BEFORE SPENDING YOUR MONEY.

Can One Radio Do Amateur And GMRS?

Leave a reply

Is There A Single Radio That Can Do Amateur Radio And GMRS?

This is kind of a trick question.  Technically, there are radios capable of doing this.  And you can buy these radios today.  The inherent problem though is that these radios violate the United States Code of Federal Regulations (CFR) Title 47 and FCC Rules and Regulations for Amateur Radio and General Mobile Radio Service (GMRS) radios to include Family Radio Service (FRS) and Multi Use Radio Service (MURS).

Amateur Radio GMRS

Baofeng UV-5R Pre-2021

Actually, a few years ago there were radios being imported into the United States that were capable of VHF/UHF, FRS, GMRS, and MURS.

If you bought the venerable Baofeng UV-5R prior to 2021 you had all these capabilities.   In 2021 the FCC started disallowing the importation of radios that didn’t meet newly written regulations.

Subsequently, I bought several of these things when I first got my FCC License and still have them all.   The UV-5R’s prior to 2021 were the magic radios that did it all.

Radio Programming Using Customer Programming Software CPS

GMRS And Ham Radio Programming Using CPS

I think there may be a perception by non-radio users that us Hams simply buy radios and just push the microphone or Push To Talk (PTT) button.   If only it were that simple.  In this day and age most radios come with a hunk of software called Customer Programming Software or CPS.  With that CPS software, the user must create something called a Codeplug.  The Codeplug must then be uploaded to the radio.  This usually entails having a programming cable.  The programming cable almost never comes with the radio and must be purchased separately.  I swear that I will never understand this.

The first time you look at a CPS program it is just a bit intimidating.   So many fields to populated with information you may or may not know about as a new ham.

CPS Customer Programming Software

And I’m mostly talking about analogue radios here.  When I bought my first DMR radio, a Connect Systems CS800, I had no earthly idea what to do next.  I started looking a Codeplug to download.  The problem with that is your Codeplug is pretty specific to your local area.  Subsequently, It should be programmed for your local amateur radio repeaters. For digital radios it will also include your favorite talk groups.

Best Budget Laser For 2024 – ACMER P1 S Pro

ACMER P1 S Pro

ACMER P1 S Pro

Desktop lasers entered the consumer market around 2019.  At that time they were reasonably priced.  This is kind of unusual as new Technology hitting the market usually has crazy prices.   However, as laser engravers evolve they are getting more and more expensive.   Finding a great machine at a budget price these days is tricky.   The folks at ACMER Laser Engraver have provided me their ACMER P1 S Pro ($199) to review.

You heard me right.  $199 on their website.  It is also available on their Amazon store for $199.  There are a variety of bundled laser kits as well which contain various options such as an air assist, honeycomb, machine enclosure, or Lightburn software.

Any time a desktop laser engraver pops up in the $200 or so range it excites me.  And this laser really excites me.  I have MANY desktop lasers that I have reviewed and believe me when I tell you that I can tell the good ones from the bad ones.

The ACMER P1 S Pro is a good one.

Munbyn RW401AP AirPrint Thermal Label Printer Review

MUNBYN RealWriter 401 AirPrint Voice Controlled Thermal Label Printer

Munbyn RW401AP Label Printer

Munbyn RW401AP AirPrint Thermal Label Printer

I was recently provided a Munbyn RW401AP  ($299 retail) Thermal label printer to review.   There was zero pressure applied by the nice folks at Munbyn for a positive review.  What you will read here is what I think.

People occasionally send me things to review and it speaks volumes about a product when a manufacturer provides one with no strings attached.  That means they trust their product.

I have owned lots of label printers and primarily use them to print shipping labels.  There are a lot of thermal printers out there that can perform that mission.  So, in this day and age you have to stand out from the pack, with new and cool features.

I believe Munbyn has done just that.

Before I get into this I’d be remiss in not pointing out a couple of connection issues I ran into.   These may or may not impact you as I run a pretty unusual network stack in my home.  In fact they probably won’t impact you.

Let me provide a few details.

TGIF Network On WPSD Digital Mobile Radio (DMR)

I’ve been using Digital Mobile Radio (DMR) for a few years now.  Essentially, DMR uses the backbone of the internet to communicate.   You can enter that network by using a radio to local DMR repeater connection.  Additionally, most people enter the DMR network by a Hotspot device connected to their own WiFi or Ethernet home network.   The most popular DMR service is the BrandMeister Network, but over time a couple other networks have sprung up.   Today I’ll be discussing how to connect to the TGIF Network.  While TGIF has been around a bit, yours truly just discovered it.  Connecting to it wasn’t as easy as I anticipated so I thought I’d write a few pointers in this blog to hopefully help others.

Quansheng UV-K6 Radio Review

Quansheng UV-K6

Quansheng UV-K6

I own several handheld VHF/UHF radios. Some are for Digital Mobile Radio (DMR) but all do analog or simplex frequencies.  I think just about all of us cut our teeth on the Baofeng UV-5R.  I’m no exception.  I think I have 2 or 3 around the house here somewhere.  On a whim I decided to buy a Quansheng UV-K6 radio which also is designated as UV-K5(8).  FCC ID information can be found here.

I recently purchased a Wouxun KG-Q10H which I really feel is the best handheld I’ve owned so far.

The only reason I picked up this Quansheng UV-K6 was for its ability to flash open source firmware onto it.  Additionally, the radio can be unlocked to transmit on a whole slew of bands.

The bad news here is that of course is against FCC Regulations.  Secondly, because the radio is a VHF/UHF radio, transmitting on any band other than those will be done in milliwatts.  So not only are you breaking the FCC rules, you aren’t really doing anything but spraying out weak transmissions with tons of 2nd and 3rd order harmonics.  In fact I’d recommend NOT unlocking the all the frequencies.  There is a difference between unlocking the radio and unlocking all frequencies.  Those are two separate actions or steps.  Don’t unlock the transmit frequencies so you don’t accidentally do anything illegal. 

Despite all this the radio is SOOOOOO hackable as to be almost irresistible to a guy like me.

Wouxun KG-Q10H Review

On February 22nd a massive cell phone outage was realized by AT&T and others.  Yesterday on Super Tuesday there was a large scale cyber attack most prominently targeting Facebook and Instagram.  If you dig a bit deeper the attack hit a lot of other prominent sites as well.  Also, a couple of months ago I woke up in the middle of the night and there was no Verizon cellular service and I had no internet with Spectrum.   Clearly it is time to bust out the Amateur Radio Equipment and even to add a new radio to the stable.  Today I’ll be reviewing the Wouxun KG-Q10H Quad Band Radio ($219).

Wouxun KG-Q10H

Wouxun KG-Q10H

Wouxun (pronounced OCEAN) is a Chinese Radio brand sold by “Buy Two Way Radios“.  While most of us amateur radio operators tend to think of Chinese hand held radios as junk, the reality is that the Wouxun KG-Q10H has been tested to death on-line and the results are pretty favorable.

Good power, good audio, and the radio passes all the FCC tests regarding spurious emissions.  Think 2nd and 3rd harmonics.   Conversely, it doesn’t spew RF all over the place like a lot of cheap radios do.
