There's 553 MBytes of photos. ? Photos take up the most of the space. ?All but the last month of that is up on Yahoo. ?I suggest all photos get archived in case Yahoo disappears, then remove everything older than a year. ?And we maybe show a bit of restraint going forward.

> ?It might also be worthwhile to consider combining "photos" and "files" into one section.A photo is just a file, a document like any other form. I'm not sure there's a reason to distinguish between JPG documents and PDF, DOC, XLS, or any other type.

True enough. ?Except that PDF's, DOC's, and XLS are almost always much more informative.

Since I haven't heard anything about the funding idea I posted before on this subject, I thought I'd re-post it in case it didn't actually go out the first time (with some emphasis added):

There is at least one online service for making contributions to creators of web content. It's called Patreon. . The minimum contribution is $1.00 USD. It's used by a lot of YouTube creators and other artists, writers, etc. Dave Jones of EEVBLOG uses it. Either Farhan or Hans could set it up. Out of more than three thousand subscribers to this group, $120 per year should be easy.

Regarding ways to delete or lower the storage burden, I would hate to see the attachment feature go. It's one of the great features of Groups.io. With Yahoo, when a poster referred to a photo, it was a PITA to go to the Yahoo site to look at it. Having it right in the post itself is the most natural way. It's how we usually do our emails for other purposes.

Regarding the files section, with some exceptions I have not found it to be particularly useful when it was at Yahoo, mostly because there was no way to search it with keywords, and no organization to the folders and files themselves. Generally, folders were/are named for the contributor, i.e., by call sign, rather than by content and with no way of knowing what's in them except by opening them up and rooting around. Often folders and files would be created as addenda to a specific post or thread, but outside of that original context have little meaning or value. I have not yet looked to see if files and folders can be searched by keyword in Groups.io. I hope so, as it would make a money contribution to support it a no-brainer.

It might also be worthwhile to consider combining "photos" and "files" into one section. A photo is just a file, a document like any other form. I'm not sure there's a reason to distinguish between JPG documents and PDF, DOC, XLS, or any other type.

Hi John.

Thanks for the reply.?

That may be a path I choose to take but I'm not quite ready to give up on this one yet. I've been hacking away at this particular assembly for a while now and it's all soldered together. I'd rather give this another go before breaking it all back down. Again, thank you for your advice. I haven't ruled it out, I just want to see if anyone has any tips to show me where I'm going wrong in this particular scheme. There must be a fairly large number of people who've gotten the rig running as I've described, anybody got any hints?

What's wrong with holiday tins? You probably already have some. You can get them for .50 cents at thrift stores, and they have a selection of shapes and sizes. Sometimes you can find metal lunch boxes that have never been used. You can rub the paint with very fine steel wool until the shine comes off. Then spray it with primer, and or paint. Then stick on some adhesive rubber feet to finish it off.?

It is best to let the paint harden for a few days. This part is something you could do while you are waiting for delivery.?

And preppers can get some to put their radios in to protect them from the big EMP. Sometimes you gotta laugh.?

?? Mounting holes chart.

I am building, creating a Bitx40v3 Metal Enclosure and intend to put speaker mounting holes in the top lid for a 3" round and 4" round speaker.? Would like to know what speaker size people are choosing for their Bitx40v3 Radio.? 2", 2 1/2" , 3", 4", 5", 6", 3"x5" oval??? It was mentioned that approximately 2" size sounded tinney??? Your experience?

ps.? add any URLs for for mount Mounting holes

In a former job I used to buy plastic enclosures from a company that would machine/paint/silk screen them per my specifications. They would also spray the inside with a conductive paint for RF shielding. I tried recently to find a similar paint but nothing was available in reasonable quantities and reasonable cost.?

Cold Galvanizing paint is an interesting option. Rustoleum even sells that in a spray can. Any idea how we could test the effectiveness of that paint for RF shielding??

The guy who turned me onto the BITX 40 got the analog one shortly before I got the digital tuning one. He had the same parts, but not assembled like the Raduino. It made sense to him to run the raduino code and put the parts together in a similar way. If you go back to the hfsigs.com site, look at the circuit description, download the schematic, connect the parts accordingly. Run the original sketch from-??And use a 10k potentiometer for tuning to start with. Then make your changes to the code for a rotary encoder.

The original code has the settings you need to get it on the right frequency. I just happened to think, you could look at the Raduino code for the specific info you need for your code.

And I don't know if he ever finished it. He's a linux admin, and father of two. And our Tech Net repeater is down.

Good evening folks.

I'm hoping someone out there can give another assist with the Arduino code. I'm getting pretty frustrated with this thing and I just can't find the part(s) of the code I'm getting wrong. I'm sure it's something basic. I just can't see it.

I'm working with a non-raduino Bitx40 (#80!) and am trying to tune it with an Adafruit Si5351, rotary encoder, and a Arduino nano. I'll attach code, taken from AK2B's blog, below.

The two issues I'm having are:

1) I cannot seem to put the right numbers in the code to get the rig on frequency. I've measured my Bix40 BFO at around 11.97MHz, so the Si5351 should be running around 4.97MHz on clock 0 correct? No matter where I put those numbers I cannot get in the band. I was able to receive signals today but there was nothing I could find that would give me a good fix. It's pretty much deaf to the LC VFO for the 40 DC receiver I've got in parts on the desk next to it. This is beginning to drive me up a wall.

2) while you all were kind enough to help before, and the frequency readout on the LCD does change when the encoder is turned, the actual frequency does not until the button that changes the increment is pushed (the encoder does not have an integral button). I've tried adding the display_frequency() command in a couple places (as you can probably see below) to see if the sequence made a difference, but it doesn't seem to change the behavior.?

So those are the issues. Like I said, I'm sure I'm betraying my ignorance of something simple, but I've run out of ideas at this point. The code below is probably as much an illustration of that as could be. My apologies to it's original author.
