I've used Pi-star now for around a year and a half. The first screen I used with the Zumspot was a 0.96" OLED screen (I thought it was awesome!) but after a while I started seeing other amateur radio guys were using the Nextion screen/s These are an amazing piece of equipment they run on 5v and have many uses, the main one I'll be using is the NX4832K035_011 this is the advance type. Basically the only difference between the two (normal & advanced) is the on board memory, RTC and GPIO available for use with external items (not used for MMDVM)
As you can see above there are six screens! I used a sheet of 400x400x8mm polycarbonate (plexiglass) and cut it down to make it match the border (25mm) There is still enough space to get access to the micro SD card for updating the screen code.
Here's the finished product in place, I'll need to do a bit of cable management as it's bit untidy but overall I'm happy with the end result.
New radio day (well two days ago) I've been lucky enough to have been bought (birthday) the Yaesu FTM-7250D to replace the Yaesu FT-90R that has been in the car for almost as long as I've owned it! So far I'm impressed with the radio and its operation is almost identical to the Yaesu FT-70D hand-held.

It's early days, but would I recommend this radio? Yes I would, because for the price ($399AUD) you're getting a dual band & dual mode (FM & C4FM) radio.

Pi-star is a great hotspot operating system for the raspberry pi and a few other SoC (System on Chip) that has been embraced to pretty much be the standard for multi mode digital voice. But there's a very dark side to the small group of people who are the Admins/Moderators for the Facebook group and the Forum. These people are totalitarian and will not take criticism for their actions.
This is a post to the Forum from me complaining about being soft banned from the Facebook group for what all I can assume was to refer a person to a thread on the forum where another person was complaining about his posts to the Facebook group were being deleted and or the comments being switched off. Then the next time I went to check out that forum post it was removed! Ok so I figured that I would start a new thread (picture above) that lasted for about a day and it was deleted.
So I started another thread, oh and you guessed it, deleted!
So again I started yet another thread… Deleted!
Ok so it's pretty obvious that whoever the admin/moderator that keeps deleting my posts has a problem with my complaint!
So this is the final post on the topic and as of the time of writing the above post was still available… But for how long?
So if anyone else has issues with the pi-star Facebook group or Forum you're fucked because if you raise the issue you will be deleted by these spineless cunts who clearly believe that they are of a higher value than any one else…
It now appears that I have been banned from the Facebook group as it's no longer visible from my Facebook account. Also I ended up posting one last post on the forum…
And yup you guessed it… Deleted. Not sure if I'm banned from the forum as I can still view it on Tapatalk.
For those familiar with the UV-5xx series radio's they are targeted for Amateur Radio use (that may change in the future) for both the 2m VHF and 70cm UHF bands however this model also includes the 220MHz 1.5m band (predominately used in the USA)
1800mAh Li-ion Battery
Dual Band Antenna
220MHz Single Band Antenna
Desktop Charger Adapter
As there are two antennas supplied you need to ensure that you use the appropriate antenna for the intended frequency otherwise you will damage the radio. As the 220MHz band is not permitted here in Australia my testing for this radio was limited to the 2m & 70cm bands.
Specifications & Functions:
Frequency Range: 136-173.975MHz, 220-225MHz, 400-519.975MHz
FM Radio: 68-105MHz (RX)
Memory Channel: 128
Output Power: 5 Watts
Tone Scanning: CTCSS, DCS
Wide/Narrow Bandwidth Setting
This radio works well and the build quality is good, although for the Australian market having access to 220MHz is of no benefit as VHF DVBT is primary service and there is no 1.5m band available within Australia.
I was lucky enough to be selected to review the GA-5S dual band FM Radio. I've never used or owned any of these entry level Chinese radio's so I was interested to see how they compare to some other known brands radios!
Unboxing this radio reveals that it comes with…
1 x Radioddity GA-5S
1 x 1800mAh Li-ion Battery
1 x High Gain Antenna
1 x Charging Cradle (with 100~240V Power Adapter)
1 x Belt Clip
1 x Earpiece
1 x Wrist Strap
1 x User Manual
After assembling the radio (antenna & battery) and powered the unit to find that it was programmed with frequencies that are not for general use in Australia, this is not a problem as I'll be reprogramming this for the 2m and 70cm bands and limiting the receive to the amateur bands only (144-148MHz 430-450MHz) as the ACMA are not to keen on these radios because of how easy it is to use them on frequencies that are not for the general public. Now I've not had or used baofeng radio's before so this is essentially the internals of (from what I have read online) a UV5-R. The supplied software for programming the radio is very basic, but it is compatible with Chirp so you can take advantage of the repeater database and import your local repeaters. At the time I first tried Chirp the support for the GA-5S wasn't available, but on the second reprogramming I did the latest daily build had included both the GA-5S and the UV5-RX3.
For the price point this radio is targeted for its certainly fine, however I'd possibly not run it on full power for extended periods as the radio will get hot!
