MAR-3SM+ and new display/VFO board coming

Jack Purdum #23288 Was on vacation with no internet...a promise to XYL. I used the MAR-3SM+ part for the?antenna analyzer (AA)?project because it's easier to find. Right now, I'm using the same AA board for the display/VFO and it seems to be doing well taking the VFO output via RG174 to Farhan's input pins. That said, Farrukh is redesigning the board to bring almost all of the Arduino Mega 2560 Pro Mini pins out to header pins to make it easier to experiment with the BITX40 (I'm lazy...B40). You can see pictures of the AA board that supports the AD9850/Mega and the TFT display by looking at the assembly manual on QRPGuys.com (look for the Antenna Analyzer menu option). The beta for the new board is being tested and I would guess it will be three weeks before we have the "real" board done. I have the code done so that it will autosize to a 2.4", 2.8", 3.5" and 3.95" mcufriend.com TFT displays. That should give some case flexibility.? Dennis Kidder (W6DQ and my co-author on the Arduino Projects book) is working on a CW and AGC options for the B40. I'm working on the code for a capacitive touch keyer (from the Projects book) which will do away with the need to drag a paddle with you. Setting CW speed and other menu options as well as tuning it done via a rotary encoder. The code provides for three CW messages to be tied to 3 NO switches on the top of the case. Each switch is tied to one of up to 50 canned messages (changeable at runtime). Press one of the switches and that message is sent via CW. The currently-selected message is displayed at the bottom of the display. It also monitors input voltage and has an S meter. (A repost of the display is below.) I don't know what we'll charge for the board, but it is a little bigger than the AA board to accommodate the different display sizes. All I can say at this point is that it will be less than $10.

Jack Purdum #23353 The board is being sold by QRPGuys.com. Both of us have been caught off-guard by the response, as they sold out of the first shipment of 50 units in 2 days. I sent them another 50 yesterday, but you should check with them to see if there is a back-order state. I have ordered more boards, which should be here in 11 days. You can copy-and-paste the code from the manual. If you need help on how to do that, let me know.

Jack Purdum #23365 The sales surprised us; they sold out in 2 days! More boards are on the way. Keep us posted on your build. Also, if there's any "fuzzy parts" in the assembly manual, let me know.

Chuck All Messages By This Member #23511 Hi Jack, Thanks for being a frequent and sage member of this group. I am very much interested in a AGC, CW, and "S" meter solution for my Bitx40 XCVR. I really hate ugly construction and breadboarding. Always looks like hell. If you can think of how I can help you, please don't hesitate to ask. It's been awhile but maybe I could remember most of my "C" programming. I really like this little QRP rig. Thanks Jqck! 73, Chuck K3VPZ
Darryl Harvey All Messages By This Member #23512 开云体育 Jack, FYI - yesterday I ?ordered 2 x boards, and today they are listed as shipped, so they must have stock again. I’ll keep you posted on progress. thanks Darryl toggle quoted message Show quoted text On 15 Mar 2017, at 2:17 am, Jack Purdum via Groups.Io <econjack@...> wrote: The sales surprised us; they sold out in 2 days!

Jack Purdum #23528 I shipped them on Monday and they got them today! Pretty fast to the West Coast from OH.

Jack Purdum #23529 Dennis Kidder (W6DQ and co-author of the Arduino Projects book) is the brains behind the changes we're making; I'm just plugging in the code. When we're done, everything will be put into Open Source and the PCB will be available, too. Farrukh is redoing the PCB to bring out more of the Arduino Mega pins to headers to make hacking the system easier. We're working like crazy to get everything done for the FDIM conference where it will be presented.

Kelly Jack All Messages By This Member #23593 Jack Is there a group for discussing the analyzer? Wondering if any other component adjustments were required for the MAR-3SM+. Regards? Simon VK3ELH
Roy Appleton All Messages By This Member #23603 If there isn't, it would probably be a good idea, as many boards that have been sold already!

Jack Purdum #23613 You can read the assembly manual and find that there is a substitute part for the IC. It is a SMD, but I had no trouble soldering it to the board and I'm two years younger than dirt. You can find the assembly manual at QRPGuys.com. They also sell the PCB.

Jack Purdum #23622 I have a Yahoo group named SoftwareControlledHamRadio and some posts are about the antenna analyzer. No other components need to be changed.?

W6IDS #23690 开云体育 Hi Jack, ? Forgive me, but as a newbe to the group, I’m still playing catch up with the BITX project and your own MAR-35M and display board. ? I did go to the QRPGuys and look at the analyzer information.? I’m now assuming that? newbe can do the task of programming because of the stable code.? It would have to be an error on my part for it not to be done properly.? I’m speakng to the board assembly as well. ? Am I to wait for the release of your new PCB and code before purchasing?? It’s not an actual complete kit per se, right?? Would the new boards be purchased from QRPGuys? ? I read where many current boards have been purchased for the analyzer.? Are people assembling the unit, installing the code for practice per se?? Then, when your code is released, remove the analyzer code and install yours for the digital display? ?

Jack Purdum #23692 Howard: I wrote the assembly manual for 24 members of my club who have already built the kit. About 5 of those had never built anything before, so I feel that the board and the code are stable. QRPGuys are only selling the board, but they sold out the first shipment of 50 boards in 2 days. They have almost sold out of the second shipment of 50 boards. The PCB board is not really "new", but is the same one that my club members used. It's only "new" in the sense that I've had to reorder the board several times because more people have purchased it than we expected. I am not selling the board; only QRPGuys are. You would need to order all of the parts for the board yourself. You can read through the list of parts and the assembly manual, as those are free downloads from their site. That should help you decide whether you want to purchase it or not. 73, Jack W8TEE toggle quoted message Show quoted text From: W6IDS <w6ids@...> To: [email protected] Sent: Sunday, March 19, 2017 1:36 PM Subject: Re: [BITX20] MAR-3SM+ and new display/VFO board coming Hi Jack, ?
