Finally got around to setting up my new duplex hotspot for DMR and Fusion(C4FM/Wires-X)
Being a vintage computer collector (My Retro Computing site) and a amateur radio enthusiast its always a nice surprise to find some software that covers both bases.
On a disk I found today was some ATV software by Ron Bray G8VEH for the BBC Micro. The software designed test cards and other screens to be transmitted over ATV.
After reading the read me file that came with the software, I re-configured it for my call sign and locator. Take a look through the screen captures I have taken. I took the screen shots from inside an emulator. I have tried the software on the real hardware and it looks great!
Unfortunately, I don’t have the hardware to transmit ATV signals.
Here is a copy of the instructions that came with the software readme.txt
I will upload a copy of the disk if I can get approval from the writer of the software.
I use AVRDUDE to programming this chip. You run AVRDUDE in a command prompt in Windows, and in a shell in Linux.
This is the command I used to upgrade to version 3.06 of the Ultimate 3 software. Obviously, you may find that you will need to change the COM port.

It is understood about 1,000 amateur radio licences will be in the first batch set to be revoked by Ofcom
Prior to the introduction of the lifetime licence in December 2006 licences had expired if not renewed annually. After 2006 Ofcom were still able to cancel lifetime licences if requested by the holder but it appears a process was not in-place to enable them to revoke an amateur licence.
If Ofcom wishes to revoke a wireless telegraphy licence, it must follow these steps:
• notify the licensee of the reasons for which it proposes to revoke the licence;
• specify a period in which the licensee may make representations;
• decide whether or not to revoke the licence within one month of the end of that period; and
• notify the holder of its decision within a week of making it.
The first batch to be revoked will comprise Amateur Radio Licences which were due to be revalidated between September 2012 and January 2013, both months being inclusive. Ofcom will be using the last known postal address held on file for correspondence with the holder.
How to revalidate your licence
So, I’ve finally had some time to do a few QSOs. In 2014, I did a total of a whopping 29 QSOs. So far in 2015, I’ve done 30!

The Russian ARISS team members plan to activate SSTV from the International Space Station on Thursday, December 18 and Saturday, December 20, 2014.
Expected SSTV mode will be PD180 on 145.800 MHz with 3 minute off periods between transmissions. A total of 12 different photos will be sent during the operational period.
Start time would be around 14:20 UT on December 18 and 12:40 UT on December 20. The transmissions should terminate around 21:30 UT each day.
SpaceX will be launching to the this week and delays in the launch could change SSTV operational times.

In the face of the internet, mobiles and instant messaging you might expect the hobby of amateur radio – or ham radio as it’s also known – to be on the decline.
But in the last three years, the number of amateur radio licences has risen by over 8,000 – with 80,000 currently issued in the UK.
Using designated frequencies, amateur radio enthusiasts communicate with people over the world. Many prefer the relaxed approach of ‘rag chewing’ or chatting at length with people, who often become friends – while at the opposite end of the spectrum ‘contesters’ compete to make as many contacts as possible in a given period.
