The last thing I ordered from Newark was also shipped from the UK with no shipping communications and as I recall took a long time. It was also an obsolete component by DigiKey and Mouser. Keep us posted. Jim Ok, Bob. The picture sure looks like there are "holes" there, but you never know. I do think that I asked Zach to put the connector on the bottom so it would line the ribbon cable up correctly with the RTIHU connector. We'll find out. BTW, Newark says they are sending the board from the UK.

Burns, I believe he is talking about a 10 pin connector on the bottom left corner of the photo that is turned down below the board. He probably did this to make a standard ribbon cable work with female IDC connectors on each end. We can make that change if the boards are shipped.

I was just going to use my existing cables to test it. Bob may need those. Not sure what JTAG connector he used on his board. If this actually works, we should order maybe 10. We might need some for Golf too so maybe 20. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Fri, Dec 8, 2023 at 10:56 AM Zach Metzinger <zmetzing(a)pobox.com> wrote: > On 12/8/23 09:41, Burns Fisher (AMSAT) wrote: > > Thanks, Zach.

TMS570 Debug board
by Burns Fisher (AMSAT) 08 Dec '23

Zach, I happened to notice that Newark still has some of the DEVPACK boards in stock. Now Newark is not the most reliable of sources, but they are cheap. Anyway, to everyone, I ordered two plus a similar one they Newark listed as a replacement. We'll see what happens. Note to Pacsat folks: It appears (and Zach can confirm) that Zach must have just ADDED a connector into a DNP space on the board...this is based on the pictures. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software*

Pictures of my debug probe
by Burns Fisher (AMSAT) 08 Dec '23

The ribbon cable has the same connector on both ends...Zach replaced the connector on the debug board with one like he has on the RT-IHU (or maybe it was even just changing the gender). You can see the number of the big chip on the bottom, but I could not even make out the numbers on the little one with a bright light and mag goggles. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software*

TMS570 JTAG interface
by Corey Minyard 08 Dec '23

08 Dec '23

It looks like the launchpad uses an XDS100v2 chip for going from USB to serial ports and JTAG. TI's web page on it is https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_xds100.html The USB device ID would be provided by the XDS100, so as long as you have that chip, it should just work. I've used Olimex before for other things, and that adapter is 55 euro. Anyway, we have options. -corey

Original PacSat Frequencies
by Jim McCullers 01 Dec '23

01 Dec '23

The original PacSats used these frequencies; AMSAT-OSCAR-16 Uplinks 145.9 - 145.92 - 145.94 - 145.96 Downlinks 437.025 - 437.05 LUSAT-OSCAR-19 Uplinks 145.84 - 145.86 - 145.88 - 145.9 Downlinks 437.125 - 437.1 There is no mention that the second downlink was used for packet or telemetry. The article does mention OSCAR-19 had a modified CW beacon for telemetry but does not indicate that was the second downlink. OSCR-16 carried an experimental beacon on 2401.2.
