The answer's just up thread a bit, mate. ?/g/BITX20/message/23001?p=Created,,,20,1,60,0::recentpostdate%2Fsticky,,,20,2,0,4438163 (

Harry, Should work on the iPad too. For PTT, the HTs that I was using both provided VOX. Here is an article about building a poor man's Signalink USB out of a cheapie USB sound card dongle.

Dear Ashhar, I have just created a pull request on your Github repository. So that you can easily review the changes I made. If you agree with the changes, please merge with your bitx40 master. So

I have added more structure/sections to the wiki. Please review/comment/contribute. Need short, complete write-up for each topical area. Can be as easy as expanding upon a post that you have already

Looks like the idea for using the BITx40 on digital modes is not as straightforward as I would have liked. I may order it just as an educational project - always had trouble with C, this might be the

The LCD connections are shown on the schematic available here: BitX40 schematic ( http://www.hfsigs.com/bitx40v3_circuit.html ) -- Ion VA3NOI

For your yeas FT-817 project, ...please contact me offI do have a complete FT-817 tech' supplement, basically totally new/91pgs still in orig' clear wrapper/pls contact me off of here use my QRZ

The BAT54S's want 7dBm vs the 17dBm on your mixers. ?Hence I figured +10dB, or 10x the power. I doubt that Si5351 can drive 50 ohms to 2.8 volts. ?Table 3 of the datasheet says output impedance is

Hello, I compiled last raduino.ino, but have problem how to connect on lcd. Can make and sketch how to connect arduino and lcd 16x2. Best regards Matjaz

i heard that there are modes like 8mA mode in SI5351 programming. Perhaps that could deliver high carrier levels. You may try to explore that before really adding an extra amp

Jerry wrote “The LO injection would have to be 10x the power”. Well I totally forgot to convert the 3V (probably about 2.8V) P-P output of the SI5351 to an RMS value for calculating the 5351’s

I thought there was something "not right" when I did the calibration on my BITX40V3. But I don't have your flight time in the cockpit. Short and sweet of this message- Because of popularity since

Fred I believe my links were embedded within the text of my message. I also use Google's Shortener. It was W9GHO that commented about the long links. Randy

Investigate, yes. Implement, not yet. Those easy-digi boards are simple but effective as an isolator and a serial ptt. If you don't have a serial port, you'll need a USB to serial converter anyway so

Randy, You can take those crazy long URLs to tinyurl.com and it will turn them into small urls that are easy to copy. v/r Fred W4JLE Sent: Tuesday, March 7, 2017 9:29 AM To:

Hi I was using my Easy Digi card to interface my iPhone to my BITX40. I built a couple of these to interface HTs to iPhones when I was playing around with 2M SSTV. I posted two videos about this

Hi! Simon, I suggested a cap that is in series and not to ground. The cap c122 charging when the TX voltage came on was the issue. It helps if there is a 1K resistor parallel to C107 to

It would also be nice to have the Coil and Transformer winding details that have been asked for by many already!!!! Ray Koster G7BHQ

As much as I'd love to see a kit for the uBitX released it may not be feasible in the immediate future.? Instead it might be more realistic to create and release things like PCB gerber files, BOMs,

Thanks Jack. BTW - I thought that your name seemed familiar. Looking back in the library I see that I have from 30+ years ago: C Self Study Guide C Programmers Library C Programming
