Has anyone found a reliable source for the correct version of the AD9850 DDS module for Jack's TFT/VFO board?? I am dreading waiting a month for the slow boat only to find out I got the wrong one.

There seems to be some confusion about how U2, the SMD part, is oriented on the PCB. I've attached a photo that should clear that up.

DJ4MU, and All, While I didn’t try too awful hard to figure out how to make my Baofeng work UN-modified, I was not having much luck, so having a handful of these on hand, I just opened one up,

What spec am I looking for regarding the display, have seen a red on a black background somewhere. But do not really know anything about them.? Must be 2 line as the menu, comes up on the lower line,

Bob: There are several other options like the PIC32 based Fubarino Mini(32 Bit, 40 MHz, massive RAM & Flash). And like you pointed out there is the 5v/3.3v issues. There are also pinout issues, delay

Hi David,? I know. ?These Bitx40 kits are excellent. ?Glad you're having fun. It took me more time to make a box than to get on the air.? If you want to get on 70cm cheaply I suggest the Baofeng

On the Yaesu speaker/mic I have, the MH-57, it looks like mic and PTT are on the same ring, third down from the top. Will this not work with the BITX40?? Do PTT and mic need to be on different

Hi Richard. As detailed by Allard... Running Raduino v1.10 here at the moment, requires the function push to make button connected, as detailed in the instructions. The VFO drive levels for LSB and

The VFO drive levels for LSB and USB can be set from the frontpanel with the function button (SETTINGS menu). See the operating instructions at

Im using the bitx40 now for 3 weeks with a LIPO S3, giving me about 11.1 -11.9 volts (just after charge) the result is about 4.5 Watt. The 10Volt seems a bit low to me for a Lipo, of course depending

Try it and tell us! Your power output will suffer, but that is all that will probably happen

Phil, how did you set your drive level? I see LSBdrive in the code but, not having had my first coffee yet, I don't see where it is adjustable. 73, Richard

My noise was quieter one end of the band to the other than dropped off towards the top, now its fairly even, and the audio also sounds better, theres also more stations now to listen too. Did try both

Also note that there is currently a solar storm going on, this may also explain the increased noise on 40m.. see http://www.gooddx.net/ 73 Allard PE1NWL

Thanks. Off to get the LDR's on order. Phil - G7BZD wrote:

Despite the posted diagram i'm still not sure how to wire up the **unmodified** Baofeng mic to the Bitx. the speaker connections seem obvious, with ground on the sleeve of 2.5mm and other speaker

I also found out that the drive setting if too high increases the noise from the speaker. My 2x Raduino's are set at 2mA drive, now and the RX is nice and clear. maybe nothing? But as I can barely

Here is more info, attached! Raj

Thanks for all the info, most the adverts on ebay do not actually give the resistance figures, so knowing a part number instead would help, will have to get the spec sheets up, did try looking for a

GL5516 works well. 5 to 10K.? $1.60 for 20 on Ebay. 73 Ken
