A bit OT for your comment but I couldn't find an Email address for you. Someone mentioned to me you are looking for details to program an Icom U101. From memory, this uses the same method as the Icom ic H10. It may be worth searching for details for the H10- I believe they were more common. In fact, I'm sure I've programmed an H10 in the past for someone else. Unfortunately, over the years, I've programmed many radios and the details escape me at the moment 73 Brian, G8OSN www.g8osn.net
Thanks Brian, I'd given up trying to find software to program it, looks like there's DOS software for the H10 so I'll try and work out which one and then obtain it.
Plans are to test the radio on 70cm, once I know it works properly I've got 'ideas' for it.
Season's greetings to one and all. I've been fascinated with GPS and GNSS in general for quite some time now, it feels rather miraculous that, for only a few pounds, I can buy a module not much larger than my thumb that will reliably provide my position anywhere on the planet to within a few metres by receiving signals from flying atomic clocks several thousand miles above my head. I've probably got far too many GPS receivers but recently someone posted an offer of free for the cost of postage receiver modules to the GQRP mailing list and it was too good an offer to turn down. A few days later some nice little Leadtek modules arrived, complete with coax pigtails. As well as the modules, there was a zip file with pinout for the 1mm (?) pitch connector on the underside and a datasheet for the module itself. While they're quite old, they have a SiRFStar chipset which is a decent performer and I've always found them to be reliably fast to get and hold a fix. Unfortun
A quick update, I needed a heatsink so I found one from an old PC which is more than adequate, weighing in at almost 650 grammes I reckon it should be able to handle the heat. Problem though, it's not flat. Which makes it kind of difficult to mount the board. Now, I could use some standoffs, PCB pillars cut to length but I'm a little light on machine tools to make an accurate job of it and it'd annoy me that it was 'wobbly'. As it happens, I recently bought myself a new toy. A Flashforge 3D printer so this seemed an ideal opportunity to learn to use a CAD program and find out how dimensionally accurate the printer is. It turns out, it's pretty good. And the PLA takes a thread really nicely. So, my Mini PA board now has mounts, I just need to drill and tap some holes in the heatsink.
Place holder for GQRP SCD Digital VFO Post The chip shortage has struck down the Teensy 3.2 which was used in the GQRP Digital VFO here: https://www.gqrp.com/suddenvfo.htm Obviously that's a problem. However, there is light at the end of the tunnel, the Teensy 4.0 is pin compatible so could be a drop in replacement. I downloaded the 'sketch' and tried to compile it, which failed with what looked like potentially simple to resolve errors and a *lot* of warnings about unused and uninitialised variables. The information below shows the changes I made to the V0_13 sketch and get a successful compile. Compiled for Teensy 4 using Arduino IDE: Version: 2.1.0 Date: 2023-04-19T15:31:10.185Z CLI Version: 0.32.2 Errors with unmodified sketch when compiled for Teensy 4 "Sorry, i2c_t3 only works on Teensy LC and 3.x.
