A few hotspots I have put together lately.

Post by WA6HXG » Fri May 18, 2018 9:04 pm

Here are pics of two new hotspots I’ve put together recently.
The first is a Duplex MMDVM (Dual Tumeslot) board sitting on top of a Raspberry Pi 3. It has a Nextion 3.2” screen with graphics I have edited and is in a case by C4Labs for MMDVM. I use it primarily for DMR so two radios may be used simultaneously.

The second is a Zumspot sitting on a Raspberry Pi Zero W in a Chinese aluminum case. Added is a Nextion 2.4” Screen with customized graphics. It is used for P25 primarily but YSF is also on for an occasional QSO.

I am using short Diamond SRH805S antennas mostly for portability since the hotspots are usually very close by. I will use Smiley telescopic 5/8 UHF antennas and on occasion counterpoise wires when I know I will be getting farther out from my hotspots as they provide incredible range even with such low power. Both hotspots are used base and mobile and the P25 spot is great for portable use as it fits in a pocket with a small usb backup battery. My next project is adding Bluetooth serial boards(4) to the screens and spots to take the screens wireless from the boards. They both work well through one of my cell phones hotspot features. Radios I am using include TYT-390s GPS VHF and UHF, TYT-MD2017, Motorola XTS5000, Motorola XPR-6550 and Yaesu FT1DR.

I am often on 91 and 310 on BrandMeister, and P25 talkgroup 10200...QSOs Welcome!

Ryan,

I am not sure if it's just me or not, but I am not able to see your photos.
I see photos on other posts, just not this one...

My apologies!!!
I have fixed the links. Apparently QRZ does not like linking to their image hosting directly...LOL

Thanks you very much Andy for your work on PI Star! It is incredible and makes using these an absolute pleasure!
The new features including cross modes are great!
My HF rig is sitting collecting dust as I am now able to connect to hams all over the world with ease and perfect audio clarity.
Currently I am exploring features like texting, GPS/APRS (which I have working) and looking at trying to implement some answer back services included in some of the mototrbo implementations I have discovered.

Now into designing the Nextion layouts...
They now have the ability to show last heard as well as current active callsign, a nice addition!
I know...REMOVE THE DARN PLASTIC COATING!!! When I am done fabricating the vehicle and dektop mounts, I will. :)

Update: The latest layouts I have put together may be found on github: https://github.com/WA6HXG/MMDVM-Nextion-Screen-Layouts

I have designed a new layout for 3.2” Nextion displays for Dual Time Slot Pi Star users. Features include last heard and last heard talk group. I have linked the files, included instructions on how to use the Nextion editor, and edit basics to get TFT files uploaded to Nextion screens on my QRZ page (WA6HXG)
Enjoy and 73,

Glad to. Thank you for your website! It is very informative and I am sure it has helped many many people get into DMR successfully. I know it has provided me much support!
You truly embody the ham spirit of helping others.
