Re: To buy a Pi
#raspberrypi
Most are just sold out. The manufacturer can't get the bits.

¿ªÔÆÌåÓýOops! SORRY! One omission! I did find on Amazon a "LoveRPi 4GB with heatsinks" for $119.99. My mistake! Ken??? KC3ROF On 12/11/2021 2:20 PM, Larry AC8YE

¿ªÔÆÌåÓýActually, in trying all provided links, it appears that all are either SOLD OUT, or just not selling the RPi anymore, other than the 2GB version on Adafruit. Microcenter only lists a full starter kit, which is currently SOLD OUT, no bare bones RPi4B's! I am a frequent customer of Amazon, and they are getting difficult to find even there! I see a 4GB version listed for $112.95, which is really HIGH $$, especially when they also list a Canakit full 4GB starter kit (including case, power supply with external switch, 32GB MicroSD card with NOOBS, fan, etc.) for $129.99, and the 8GB model for $40 more (but it has a 128GB SD card!). Canakit is probably the highest rated for quality components. The Canakit also includes a neat little USB adapter for the SD card, so you can plug it directly into a USB port on your PC, or the Pi itself! I have purchased 2 of these kits over the past year, and have found the quality exceptional! But other than the Canakit, I have NOT found a Raspberry Pi 4B 8GB model ANYWHERE for sale, especially in bare format! GOOD LUCK in your search! Ken??? KC3ROF On 12/11/2021 7:51 PM, N5XMT wrote:

¿ªÔÆÌåÓýIf you use the link sent below, and click on "Buy Now", you are directed to a bunch of resellers, so it appears that they do not sell the Raspberry Pi themselves. Ken??? KC3ROF On 12/11/2021 2:14 PM, N5XMT wrote:

Re: To buy a Pi

Since you're in the US, one choice is Micro Center who has "bare" RPi 4bs.? I bought 2ea from my local store (Columbus, OH), but they do mail orders. Larry AC8YE On Sat, Dec 11, 2021 at 2:14 PM N5XMT <dacooley@...> wrote:

Re: Remote Site SSTV
¿ªÔÆÌåÓýI suppose a lot of custom code would be required to handle this, but there should be some suitable packages for the Raspberry Pi that can be incorporated. Hmmm.. ok, I can give you some ideas of some LInux projects that have components of this functionality: I'd like to put a couple cameras up there monitoring a couple different things. Any data over a repeater's audio path is going to be slow so you're going to have to de-res the pictures pretty heavily.? For example, a 320Kbyte picture will take about 1.3min via a digital SSTV mode.? ?? - GraphicsMagick to do scripted image modifications What I'd like to do is the ability to send a DTMF code to get a snapshot from a camera ?? - SvxLink has some nice scripting abilities which you can probably use to trigger various functions from DTMF. then transmit that via SSTV over the repeater Qsstv has some very powerful analog and digital SSTV modes though I don't know strong it's automation support might be.? What kind of repeater controller is running at your site?? It will clearly need another "port" to connect to the computer sending the function.? If it's a digital repeater, some versions have bulk file modes that can possibly make things faster than using SSTV.? Good luck! --David KI6ZHD |
Re: Remote Site SSTV
This project will strictly utilize existing analog FM channels at the site. However, the question is not really the transmission medium, but the nuts and bolts of taking the picture and transmitting it on command.

Remote Site SSTV
Here's an interesting project thought.
A remote base/repeater site, on a very remote hilltop. No internet or cell service available. I'd like to put a couple cameras up there monitoring a couple different things. What I'd like to do is the ability to send a DTMF code to get a snapshot from a camera, then transmit that via SSTV over the repeater. I suppose a lot of custom code would be required to handle this, but there should be some suitable packages for the Raspberry Pi that can be incorporated. Thoughts and ideas appreciated. -- 73, Michael WA7SKG "Any day you do not learn one new thing is a wasted day." |
Re: Simple Remote Radio
Chris, looks kind of interesting. Unfortunately, your pictures are too small and fuzzy for my tired eyes to see anything useful.

Re: Simple Remote Radio
¿ªÔÆÌåÓýHmmm... I've never heard this this "USDX" project so I did a little Googling: ?? - Background and a little history: ?? - Main page: It sounds like it uses some novel tricks to create a 5w SDR from an Arduino and amplifier tricks but I would be worried about both it's RX and TX performance.? Anyway, as remote control, you're already asking this on an existing email thread with some provides ideas.? Have you tried any of those options?? You would ultimately just need to connected a USB or I2S soundcard from the Rpi into the USDX's microphone in, audio out, and connecting the Rpi's UART to the USDX's CAT port.? At that point, it should be possible to remote control.? There are lots of other discussions in the archives around this topic using say NX, TeamViewer, Mumble, Skype, etc. ?? /g/RaspberryPi-4-HamRadio/search?p=created%2C0%2C%2C1%2C2%2C0%2C0&q=remote+control --David KI6ZHD On 12/04/2021 06:29 AM, ta1db wrote:
