I never looked that far to the right, never saw the option before to create a new topic from a email¡. I tested it in my group¡..same thing. It takes you to the group, and since I have made hashtags mandatory as admin. No hashtag selected, you get RED error and no creation.

Re: uBITX Case
Rod Self
¿ªÔÆÌåÓýGood idea. I am for having extra vertical room, extra front panel room, a removable/replaceable front panel, and a spot for a small cooling fan. I plan on lots of hacks (AGC board, case-temperature driven cooling fan, full CAT controls, and more- may require an extra arduino board)? and would like room on the front panel for extra controls. I know this will be in direct conflict with those who want the smallest case, so it is your judgment all the way. Maybe the hacking version could have a front panel? 1/4 the size
of a TS-440. Thanks for the idea, Rod On 12/13/2017 07:16 AM, Jeff (NT1K)

For anyone new to the group wondering if they made the cutoff ....?
If you ordered before 2pm EST on Monday December 11, then you should be getting one of the first batch, otherwise your uBITX is on backorder.? FWIW here is the timestamp for the cutoff message : Ubitx only on preorder now? From:?Ashhar Farhan Date: Mon, 11 Dec 2017 14:10:44 EST? The message that Farhan posted saying the the first batch of uBITX were sold out was? number 35564.? Cheers Michael VE3WMB? P.S. As you may notice I used the ubitx hashtag in the title. |

I just tested it in my group. If I don¡¯t select a hashtag from the list already there, because if I am not a moderator I can¡¯t create one¡..then it won¡¯t let me send the message. Remember, this is for the creation of a topic¡.not every reply. So: If there was a Bitx40 - tag, and ?Bitx -tag, and a Bitx20 - tag¡..etc, etc¡.you would select the tag when you create the topic. And yes, in search for something, the first thing you do is filter by hashtag¡¡ Now that is just my initial take on it¡.and I don¡¯t trust myself¡.so¡.

Re: uBITX Case
I would definitely buy a nice case for this project that I would not have to machine.
That said, there will likely be a couple of divergent paths for development, analogous to the BITX40 with TFT or LCD displays, extra buttons, and so forth. I'd still buy a nice case for the as shipped ?BITX.? And I think that case would work with the half assembled BITX40 so I'd buy another to finish that out properly. |
Re: Si570 Output (Sweeperino) - 100 MHs Sine?!
Anyone curious about the workings of the Si570 might look over this post: ?/g/BITX20/message/24284

and the thread in the old minima forum that is pointed to there. The Si570 has a 114.285mhz internal crystal oscillator, tolerance on that oscillator is +/- 2000ppm which is pretty bad. But you can set internal registers such that the output is some ratio of that 114.285 mhz oscillator within 0.1 ppb (yes, parts per billion!). ?The factory determines appropriate register settings for an accurate output frequency at power-up (whatever frequency you specify when ordering) and writes those register settings to one-time programmable ROM. ?At power up, those ROM values are written to the registers, but you can write new values (and change the output frequency) via the i2c bus. So, if you want better than 2000ppm accuracy, you have to know the power up frequency (not written to ROM, unfortunately) and must read the power up values of those registers. ?Given the ratio determined by those values in the registers, you can work back and figure out what frequency the nominally 114.285mhz reference oscillator is operating at very accurately, and program new ratios for new output frequencies into he registers accordingly. The Si5351 on the Raduino is relatively simple, as the crystal is external and it is up to the builder to select? a reference crystal (or oscillator) of appropriate accuracy and calibrate it.

for newbies to building, I would suggest to give a little extra ROOM inside the case for fingers to work on it.? ?I worked with some retired volunteers a few months back teaching them how to solder, and their vision and dexterity were FAR less than what
I expected.? ?
While aluminum is a lot easier to drill for the home hobbiest, it might increase your price.? ?I think steel would work out OK if most of the holes are already cut.? ?If not, then aluminum.? ?
If the holes aren't cut, then a stick-on paper thing with marks of where? every hole might need to be---and the drill needed! might be a huge improvement for thehome builder.? ?I made such a thing just for the Raduino display and was able to cut three new
mounts --- 2 in castoff cooking pans and one in plastic --- FAR easier than anything I had tried before.? ?
My 2 cents worth.

The PCB is a replacement for the Raduino board and uses a TFT color display and an AD9850 Type II DDS for the VFO: It also assumes the BITX40 CW mod, and provides for 3 external "message switches" that allow you to send stored messages from a list of up to 50 messages (useful during CW contests). The board is designed to work with mcufriend displays ranging from 2.4" to 3.5". The code also provides for an off-board RTC, too. The PCB only sells for $8, including domestic shipping. The assembly manual is available in the Files section. Note: Al Peter (AC8GY) and I are redoing the board for the ?BITX. It's still being designed but we're pretty sure we will use the Si5351 and either the Teensy 3.6 (Arduino compatible) or the ESP32. The screen will likely be a 5" color touch screen and we will likely bring the pins out to headers for experimenting. The additional resources and enhanced computing power brings a lot of computationally-intensive options into play. Since Ashhar has made the rig multiband, the screen info will be expanded from what's shown above. We are making concerted efforts to keep the price of the board down while maintaining its high quality. As always, the code will be Open Source. Al's just moved into a new home and the Holidays have slowed us down. It's too early to say when we will be ready for Beta testing.

I like the mandatory hashtag thing, assuming it is obvious how to add them while creating ?post. I assume groups.io allows me to screen in and/or screen out particular hashtags for reading. On Wed, Dec 13, 2017 at 01:58 am, Craig Thibodeaux wrote:
