Hey what about a preamp for 6-15 meters? I have a nice design for one using a PGA-103+ … only 12 parts if you include the bypass relay… Sent: Wednesday, May 30, 2018 8:05 PM To: [email protected]

Hi Curt, When those four-pin mic connectors were in vogue there was a recommendation by some manufacturers to use the fourth pin as PTT ground. Both the mic ground pin and the PTT ground pin are

I'm going to use this old light stand to make a desktop mic.? Should I attach the ground side to the flexible conduit portion?? I'm worried about hand capacitance issues. Thanks!

It's the 12Mhz SSB filter that limits the audio bandwidth. tim ab0wr "Lee" <mr.olson@...> wrote:

There is a separate library for Teensy (i2c_t3) that comes as a built in library in the Teensy add-on for the IDE. It is supposed to handle Wire1, Wire2, Wire3, and Wire4 #include <i2C_t3.h> instead

Oh wow. Allard I didn’t know you were the creator, It’s a good service. Btw just got notice that there’s some Sporadic E on 6meters right now if anyone wants to have a go at it lol. Joe KD2NFC

Hi guys, I'm going to build up my uBitx and use a standard 4 pin mic jack. ?For some reason I'm not used to seeing the circuit drawing of the jack in the Wire Up so this is my interpretation. I just

I was lucky in the box I put my uBITX in was just large enough to fit the display out a hole in the front and the heat sinks out the back. When I changed the final transistors the tab was at ground.

Great to hear this Joe! I never expected it would grow this big when I started the DXrobot in the summer of 1999. 73 Allard PE1NWL

Hi all, ? I have an unopened/unmodified BiTX-40 for sale, purchased on January 25, 2017. ?I'm just not getting enough time for projects - as is obvious between the purchase date and now! - so it's

Allard I use this service DXRobot. I get audio alerts on a simplex node I use that gives me propagation alerts. I get alerts everyday when 6m is open Joe KD2NFC

So we already have a filter to cut audio outside the 700-2800 range?? I was building a SSB-Mite from 4 State QRP Group.? I searched the messages for it and did not find anything.?? Can you tell us

I don't think the issue is the bus voltage. The issue is getting the SDA2 and SCL2 pins to work instead of SDA1 and SCL1. The Wire library seems to only handle SDA and SCL, not any of the other

Until I resolve my microphone input level I will be working CW, only. I'll call CQ BITX on, or about, 7030 KHz starting around 1900 utc. Dave WS1ETI

Or, you can use a DC-DC converter. Jack, W8TEE

Sorry, typo!? ND6T?http://www.nd6t.com/uBITX.htm

I should also mention Don, ND8T who has a site with info and some good mods:?http://www.nd6t.com/uBITX.htm

I am happy, someone’s looking at the Nextion Display. Although a bit costly, they would prove to be the best and NO-LOAD on the Arduino, I guess. Looking forward to seeing something on this line.

Wouldn't be easier to set fixed UTC hours instead of local time? Local Time just too dispersive in my opinion. kHz in North America, 7177 kHz elsewhere. on 7.277 MHz in 40 meters! 3PM and 7pm in each
