Re: W8TEE TFT/VFO Board from FDIM talk

See below: From: Joe <joeman2116@...> To: [email protected] Sent: Thursday, June 8, 2017 7:17 PM Subject: Re: [BITX20] W8TEE TFT/VFO Board from FDIM talk Jack, Thanks for sending the boards. Picked them up today.. Nice looking board!. I also received my atmega 2560 mini pro and the correct DDS 9850. Mars 3 etc So parts have started to roll in... 1. I presume the vrmini 360,atmega and dds9850 all mount on the same side - the side with the lettering. (on the same side that says tft lcd vfo lettering)? Yes. I hope to have an assembly manual written within a week which will be similar to the Forty-9er and Antenna Analyzer manual. Right now, I need to add some info to the manual about using the keyer. That will come after the code is done. 2. I was thinking of putting headers pins ?/ sockets for ?- ?atmega, dds and vr mini. Just in case of a future failure. The Mega Pro Mini and DDS boards that I buy already have either sockets or pins. The Mega has female socket for all the pins, so I mount pins on the PCB. The DDS board has pins, so I use 7-pin sockets for it. Given a choice, I never solder an IC to a board. Tayda Electronics sells pins and 7-pin sockets at a reasonable price and they are in the US, so shipment is pretty fast. Then run cables from the tft ?display and tft vfo board. ? and mount the tft vfo board on the ?radio chassis and the ?TFT display on the front panel The attached photo shows how I'm mounting the PCB for the VFO/TFT board. Does this make sense or do you see any issues? That should work fine. I'm just mounting the board on the front panel to minimize the wiring between the TFT display and the PCB.The acrylic front panel makes for easy mounting of the PCB while minimizing the wiring to the other boards. The pictures shows 4 additional boards, but Dennis will likely combine these onto one fairly small board. Any forecast on the code???If I can beg out of a weekend trip, I should have it done this weekend. Because the AGC, S meter, CW, and speech processor boards need to be finalized, I do not have that code in place. However, you can practice your CW and use the 3 CW message switches as the keyer is in place. The Pro Mini can be used to generate a sidetone, which is what I'm doing at the moment. Thanks for your service , any info / guidance would be appreciated. Ps: ?I am preping a new case ( a converted small form dell computer case , for my 3rd bitx - (for your ?Colour TFT/vfo board..) I am making sure this time, to have lots of room for big heatsink and room for ?various modules.etc.... I use my current bitx40 for mostly jt65 - works great and some ssb. Great fun for a retired senior (me) Joe? VE1BWV On Fri, May 26, 2017 at 6:10 PM, Jack Purdum via Groups.Io <econjack@...> wrote:

Re: Bitx connector pins
¿ªÔÆÌåÓýI found this crimper and it
seems to do a good job - search your favorite on-line mall for: "IWISS Dupont Professional Pin
Compression Ratcheting Modular Insulated Terminal Crimper Pin Crimping Tool
2.54mm 3.96mm 28-18AWG 0.5-1.0mm2"?
?
I found
the prices around?$20 - some higher, some lower.? There are some good
pics on the Amazon listing for this crimper.? Take a couple of minutes on
YouTube watching some?"Dupont Crimper" vidos and save yourself a lot of
frustration :-)??

My built Bitx40 raduino for sale
Hello everyone!
Since I've moved on to an all band SDR qrp rig I've decided to offer up my built up Bitx40 with raduino. The rig is built into a sheilded Hammond enclosure, is running Allard's firmware with CW and other features enabled. The front panel has a ten turn tuning pot, function and tune buttons, volume, mic and headphone jacks. The back panel has the antenna connector and fuse holder. Includes a modified RadioShack mini speaker microphone originally used with the htx202. Puts out 5w on 13.8v. I've uploaded photos to the group under the W1NCR folder. I'm asking $120 shipped within the USA. Noel, W1NCR Noelacramos@... |

I'm not talking about pins from ebay. If you bought them on ebay, you use 'em.

When they provide a datasheet, you ignore the picture. Do you think the 2 pin connectors look like the picture?

Allard, I would like to take the opportunity to thank you for yourThanks Rich, it's always good to hear that users like the software. On the other hand, I definitely don't want to encourage any procrastination. The whole idea of the BITX40 project is to encourage experimentation. So open that BITX40 box and start playing! 73 Allard PE1NWL ? |
Re: Bitx connector pins and Crimping
I have some crimpers, I think I got from Seeed.

I have had trouble using them. The pins are so small, you have to have every thing perfect. You can smash the pin or it turns sideways? You got to have good eyes. And the stranded wires can not be frayed. One thing, I use 26 Ga. wire, I got hundreds of feet in 5 or 6 colors. I have had wires bird cage (fray) while trying to crimp, so I always TIN the wire to hold the strands together. That breaks the no-solder rule. For the solder method, I use a needle nose and crimp with a roll motion the 2 sides. Solder real quick, and when cool crimp the top strain relief. Don't do the top Hot, it melts the insulation. If the solder wicks ups to the top, the wires will break from use. So, just a quick solder job. Soldering is bad for connector pins. The military and industry have developed crimping on just the wire to cure the problem of work hardening and then breaking. So only us Hobbyists can get away with it!

Re: Calling all Midwesterners.
John, AD0RW, from Coralville, Iowa. Hawkeye country, right next door to Iowa City and the U. of Iowa.
I have a choice between a dipole at 30 feet and an 80 meter wire vertical (mostly, more like half a 'Y') tuned as an end fed half wave on 40. The latter seems to work better for long haul contacts. |

That's even better, as Allard's code is pretty tight. One of my worries is that we don't fragment and fracture the group with too many processor/code variations. I'm guilty of this, too, as I will soon be releasing my firmware which uses the Arduino Mega 2560 Pro Mini. Jack, |
