Great Ken, I will try it today myself. I never use more than 220. Joel Caulkins KB6QVI

I changed the 470 uf cap to 220 uf. In the headphones it does sound better. The real test is with a speaker later tonight. Looking at the LM386 app motes, the 1 nf and 10K is to increase

Hello Guys My BITX arrive in 12 days .... a record for my country... It looks great ! I will post ...more infos... THANKS a lot 73 from py2ohh miguel

Mark, This is the official bitx40 hack blog: http://bitxhacks.blogspot.it 73 Giuseppe, ik8yfw

Fine Mark. Please post the results. When you tune a signal try to compare between two vfo, internal and external. We await your good news ! ? Giuseppe.

Jerry, Here is the body of the original post. Stuart For some months now, we have been working at a low cost, single board QRP SSB transceiver module based on the BITX design. So here is BITX

This is the VFO I am building for my BitX 40. Just started it tonight. Mark K3MRK Sent: Monday, November 28, 2016 9:20 AM To: BITX20@... Subject: Re: [BITX20] Re: BITX 40 - DDS

Thanks for the info. I have started to build the DDS tonight. Hopefully will have ready to go by the weekend. Where is the blog? Mark K3MRK Sent: Monday, November 28, 2016 1:48 AM To:

Ok, now there's nearly enough of us around to *nearly* make a Net. Regional, probably - unless you're perched on the coast of Maine, with a Log-Periodic pointed to the European continent, of

Good stuff Joel. I am very pleased with the BItx40, even though the sound is bassy. I'll(you'll) will figure it out. I'm actually thing of making it into a 40/20 rig. Just getting used to the arduino

Ah Ha! #771 has arrived safely in Cincinnati, OH. Thanks Darryl. The shack has rather low light levels and I'm old. Jack, W8TEE To: bitx20@... Cc: bitx20@... Sent: Monday,

Well, I had to finally ask after many QSOs because nobody ever made a comment on my audio. As it turns out everybody thinks I'm on a "big rig", the audio reports are excellent using my homemade

Okay...at the risk of sounding stupid...again...where is everyone getting the serial number from? There's a small white square on the board with "38 16" on it, but there is a space between the two

Hi Joel How's the audio report back to you? 73 Ken BITX20@...> wrote:

Ken, I did that also today and noticed no affect at all. I think the changes need to be made further up the audio chain before it gets to the amp. I just have too many irons in the fire to try
