I recently grabbed a SharkRF OpenSpot from Grapevine Amateur Radio. As of this post, Jason KC5HWB sells the units shipped for $215. What’s better than buying Ham Gear from a Ham! Jason does a video series on “What’s New In Ham Radio”. Be sure to check out his HamRadio 2.0 site for the latest and greatest goodies!
Since I already have a DVMega / Bluespot for the Ham Shack my plan was to set up the OpenSpot for portable operation.
Installed my Gatcepot 24000mAh 5.5A Universal 3-Port Ultra-High Capacity Power Bank , TPLink Nano Router and the SharkRF OpenSpot into the Pelican 1150 case and now go 100% portable by tethering the router to my iPhone 7.
With inspiration from Rob AK7RM’s how to (thanks Rob), I threw my How To version together with some extra info to help with the setup process. I also wanted to specifically cover the problem that hung me up for a bit. Check the note about the SSID value.
This how to is written specifically for use with the the TPLink Nano Router and an iPhone7 in Hotspot mode. However you can probably adapt it to any similar setup.

Enjoy! Hope To Catch you on DMR 73 – Gary KE2YK
Been spending a lot of time on DMR (Digital Mobile Radio) these days. Recently ordered a DVMega / Bluestack Node and have been having a ball chatting with people all over the World.
As a matter of fact I had a very nice TAC311 QSO with HL5KY in Korea on 2/4 @ 22:20 hours.
The black PI is a PI3 Mod B where I run my Web Server, custom firmware for the Tytera MD380 called MD380 Tools and do some crazy Java Coding.
The clear PI is a PI2 and I experiment with all kinds of code like the unsupported BlueDV console for the BlueStack Node.
And of course the top of the stack is the HotSpot. Right now the console is an Nexus 7 tablet running Andriod with the BlueDV console. Pleas note my HIGH TECH way of keeping the STACK together!!!
If you are interested in finding out more about DMR, you can listen to DMR Ham Radio Operators talk on the various talk groups. A good place to start is to listen to talk group 3100.
Most of all have fun! 73 KE2YK
I have a like new Wouxun KG-UVD1P Dual Band HT in original box with programming cable, extra battery and desk charger. Low usage and only selling because I have too many radios.
Will ship to CONUS only. NO TRADES please guys! Paypal preferred but will take USPS Money Order. Photos supplied upon request. Asking price is $75.
The Color display is very good and rather large for an HT.
The 2600 mAh battery life is exceptionally good and does not drain when powered off as the KG-UVD1P does.
A group of us locals have access to a 1.25 meter repeater and performance on the band is very good even on low power.
The channel / VFO Knob gets tight in spots and the screw holding rubber side cover was so loose it was ready to fall out.
Very loud reception causes the speaker to be distorted.
After purchasing the radio, I found out that there is and E and T version. The difference is that a factory reset of the E version causes the firmware to reboot to Chinese while the T version reboots to English. Of course flipping through the Ching-lish manual will save your day with the E version.
Since I only had an old (pain in the ass) Prolific chipped programming cable I also purchased the Red programming cable. The Red cable was hassle free with Windows 10. No monkeying around with the old drivers from the stone age as is the case with the old Prolific chip. Unlike the expensive RT Systems cables, the red cable was around $15. By the way, the Red cable also works for Baofeng and I’d imagine some Kenwood HT’s as well.
Again no radio is perfect but for the price it was a decent buy for the additional 1.25 meter band. If you are looking for specs or videos, Google it. There is no point in regurgitating the same information that’s already available on countless other Web sites.
Wireless Holdings sells leading edge modules and accessories to Ham Radio operators. Wireless Holdings has been in the digital gadget market over 40 years, and leverages a network of professional engineers to bring the latest digital gadgets to the market.
Why would anyone be interested in a DV4mini USB Stick? First I should explain that the DV4mini is a miniature, low power transceiver which you can use around the house or portable with any HT capable of one of the four digital modes. DSTAR, DMR Plus, Fusion or P25. Download a copy of the DV4mini manual for more detail.
In my case, even though I live in an area tightly packed with analog RF, there are no digital repeaters close enough to reliably access with an HT. Unless I connect my CS700 to my roof antenna, I cannot reach the DMR TRBO repeater in my area. Visit DMR-MARC if you want to know more about TRBO for Ham Radio.
So using DMR with the DV4mini (although not TRBO) gets me connected to the digital world using DMR Plus (Hytera systems). I cannot speak about DSTAR, Fusion or P25. My only experience has been using DMR Plus. I don’t spend a lot of time with the DV4mini however I had the pleasure of having a QSO with a Ham from Japan a few weeks back.
My 70cm DV4mini has worked flawlessly since I purchased it some months ago. As I mentioned in a prior article, I built up a Raspberry Pi with the necessary software to run the DV4mini console. If anyone is interested in my notes about building up the software necessary to run the DV4mini Console and other Raspian Jessie ramblings, stop by my homebrew Ham Radio Forum.
Recently I received an email stating that Wireless Holdings will start selling the DV4mini in a 2 meter version. Just in time for Dayton Hamvention!
73, Gary KE2YK
For those of us who take and interest in digital radio or have been experimenting with the DV4Mini, Wireless Holdings recently announced their new DV4 system called DV4home .
According to Wireless Holdings, the DV4home is going to include the following features:
- Can be used with or without a DV4mini for DStar/C4FM/DMR/dPMR/P25
- Use your radio or connect a microphone and speaker to the DV4home
- No Linux experience is required
- Simple set up with navigation on display
- Improved shielding with metal case
- Extended temperature range (-40C – +85C) for mobile use
- Works with 12 V power supply
Wireless Holdings states that the finished product will be on display at the Dayton Hamvention.
Recently I picked up a new car and decided that I am done with installing mobile radios, cables and antennas as I had over the past 30 years. I don’t commute any longer and just don’t spend that much time in the car so my thoughts turned to the idea of grabbing a cheap HT to throw in the glove box.
After owning the original UV-3R, I was skeptical about grabbing the new Dual Display UV-3R 2016 version. Remembering back to my original UV-3R, it’s problem was rejection of unwanted signals.
The area around my QTH is densely packed with radio signals. However, the advantage of signal density is that there are plenty of 2/70 cm analog repeaters to choose from. As a result the 2 watt limitation of the new UV-3R presents no problem for me.
Go here if you want detailed Tech Specs. Basically, for around $30, it’s a 99 channel dual band, dual display 2/70cm HT in a small ‘credit card sized’ form factor with a 3.7 volt 1500 mAh Li-Ion battery.
The Dual Band Screen of the new UV-3R is an asset. Manually programming the radio is pretty easy but if you are going to add tons of repeaters or fire/ems frequencies, grab a programming cable and use the free CHIRP software.
The radio has a couple of basic issues. There is no keypad so it takes extra effort to program the radio and to navigate around to change simple settings like the squelch level. The FM Radio has poor reception. But who buys an HT to listen to FM Radio anyway.
The on-board speaker is loud with no distortion. If you plan to use earbuds you will notice that the audio is muffled and the gain is somewhat reduced .
In general, any rubber duck is nothing more than a Dummy Load but at my QTH hitting the local repeaters presents no problem with the stock antenna.
Just a word on HT antennas, there are tons of knock off rubber duck antennas on the market. Buyer beware when looking for a replacement because you may end up with an antenna that performs worse than the original!
The UV-3R scans EMS and Fire frequencies fairly well. Using CHIRP, you can easily select which frequencies to scan.
No complaints. With normal use the HT ran for a full day.
Go here to grab your copy.
IMHO, for around $30, how can you go wrong? This little GEM is a great little grab-n-go HT.
So I decided to build a Raspberry Pi 2 model B using a 32Gb Micro USB Card and the vanilla copy of Raspian Jessie 8 into a fully working DV4mini Console.
I used Putty with the DHCP provided IP address to run raspi-config expanding the file system and to change default localization settings.
Then it was on to installing x11vnc so I could work from my Windoze desktop using Tightvnc. Next it was getting the Edimax Wireless card online. From there I installed Mono 4.0 (Note: an 8GB Micro USB Card will run out of space while installing Mono 4.0) and finally the DV4Mini Console.
Since I created a series of crib sheets, I put a home-brew forum together as a central repository for my notes.
For those interested, go straight to my work-in-progress forum at KE2YK’s Ham Radio and Systems Forum. BTW, You don’t need to register to poke around its contents.
