Make your DMR text messages work between various radios.


One of the first things you may notice when playing with different DMR radios of different brands is their inability to exchange text messages, in most part this is because the most high end manufacturers like Motorola and Hytera use their own format for sending data over the air, this has always been the case since DMR radios started appearing on the market however things are starting to change... In the latest Motorola CPS (version 11 upwards) there is a setting for each digital channel that allows you to select if you want Motorola format text messaging or DMR standard. To use this feature you need to make sure the radio itself is running the latest firmware. You need to also set the UDP data type to DMR Standard, this checkbox is above the text message type drop down box. For Hytera radios to exchange data using the DMR standard and not Hytera's own format you need to first update your firmware and CPS to the latest version and then in the CPS from the conventional - digital common - basic menu scroll down to the bottom to miscellaneous - data bearer service and change the setting to DMR Standard. After updating the firmware and cps for both radios you will need to read back the code plug from the radio into the CPS and save it as a new code plug. Also please note that changing these settings allows cross communication of data between radios in simplex mode, for repeaters it will probably be a different story. If you are on a Hytera network and use repeaters then I don't recommend changing the data bearer service as it will likely prevent text messaging between other Hytera radios and break things like GPS and forwarding to APRS.

Trilogy *Easy Access* Radio Beta testing phase now on

The club has been working on developing a well priced DMR hand held radio for use with the exiitng ham radio network both phoenix and brand master.

The project is being called TRILOGY and we will be testing 2 radios which will be known as *big* and *Small* Please help us by sharing your signal reports and let us know what you think.

After a few weeks of testing we will release a handful into the wild for real world testing.

If you are interested in these radios, or want to help test please do let us know.

See the page tab at the tob of the blog for the latest information (more end of next week)

MB6IJP DV4 mini hotspot

Raspberry pi 3 running dv4mf2 software for dv4mini hotspot MB6IJP in Staines Middlesex.

SSTV ground station MX0MXO ready!

Station ready to receive SSTV from newest satellite

First few EQSL.CC cards for GB9LIZ **Thank you!!!**




STMSat-1 is planned to deploy from the International Space station on 16 May between 1400 and 1500UTC



The slow scan television CubeSat STMSat-1 is planned to deploy from the International Space station on 16 May between 1400 and 1500UTC.
It is thought to be the first amateur satellite to be built by elementary school students, who are aged between five and 10 years old.

It is expected to transmit using the Robot36 SSTV mode on 437.800MHz.

Find out more from AMSAT-UK article.



 
















Thank you for your interest and support in our mission!

Please find your RMOC certificate attached.  

If/when you receive images, please email them here. I will post them on our social media outlets with credits given to you.  :)

Looking forward to working with you.  Cross your fingers for deployment tomorrow!

Special event station GB9LIZ granted for May and June

To celebrate the Queens 90th Birthday OFCOM have very kindly allowed us to use the special event call sign GB9LIZ.

We will be operating as often as possible and as many modes as possible, but please look out for our call sign over the weekends on 20 / 40 and other HF bands.

During the week we will be on DMR and reaching out to local repeaters.

We are creating several SSTV images and are hoping to transmit these from the park area on 14.230 USB.

We are using qrz.com to log all of our contacts and will be sending out a very special QSL card as pictured below.
