They plug into USB. See the web page tarpn.net/d for more info.

I think that is a DROKay variable output regulator. its cool feature is it can put out > 5v to the USB connector making it ideal for powering a modern Raspberry PI at 5.2VDC. Here's a search string to find the DROK device DC-DC Buck, DROK Power Supply Module LM2596 DC Buck Converter 5V-36V to 1.25-32V Step Down Voltage Regulator Stabilizer 3A 5A CC Volt " de KA2DEW

Should. I Did not have what it takes to make it work correctly. I gave up and spent $15 to buy another stripper.

Zack, contact me via my qrz.com/db/ka2dew email address from QRZ. Let's do it.

I use QSRADIO.com as a supplier Amazon offerings are inconsistent. Some great deals, some ripoffs. Amazon ratings system is confusing because somebody gives a rating for a product which then shows up in somebody else's offering for the product, but the somebody else might be a rip-off artist. The rating may not even be for the same version of the product. I use Amazon quite a bit, but you have to beware and be aggressive with Amazon when they send you trash. QSRADIO has been very responsive, responsible, and fair. That said, QSRADIO does sell some good products which are available cheaper elsewhere. But all of the elsewhere venders (ebay, amazon) are riskier.

@@taddinraleigh Thank you! I found the same things to be true buying from Amazon.

@@taddinraleigh I just ordered the crimper and the pl259 connectors from quicksilver. I do have a bunch of solder connectors with adapters but I use a Weller sp120 for soldering the braid and solder station for the center pin. Too much hassle and I'd rather use the crimp connectors. Thanks again!

TK8180K-1 no mods. One issue is that they require a pretty strong signal for 9600 to work well.

we have shipped 210 of the A2 model as of Apr 20. We have 10 PCBs for the A3 on hand and are writing assembly instructions and testing modes and whatnot. Some code work was required between the A2 and A3 and more code work is desired. We'll probably be ordering a for-sale batch of the A3 boards in the next week. Pre-orders are open. Check the web site for new, info, and assembly instructions. tarpn.net/d. also there is a groups.io list for this and our other packet radio projects. All on the info site.

We use G8BPQ PINLINBPQ on Raspberry PI. It can send files and chat. See this video TARPN-HOME New Year's Eve chat Dec31-2019 to Jan01-2020 kzfaq.info/get/bejne/Z9Jpha2Vub2UknU.html and also the web site tarpn.net. and ncpacket.net. There are many youtube videos tagged with "TARPN".

Dylan, you helped! We learned many things from your work.

@@taddtorborg8745 Thanks. It was a lot of fun. My area is just too rural to support the project. I'd like to farm out all this equipment to good homes.

@@drumswiper are you selling some stuff?
