Re: Increment Problems
SUCCESS AT LAST!!!!!! After weeks of trying to figure out what I did wrong, my DDS VFO is working flawlessly and the increment problem has been solved. I replaced the rotary files downloaded from

It's Alive !
OK guys, I managed to put everything together and so far is looking good. It powered up fine, so far I'm noticing that the encoder "step" function is not working when I push it down. It does move up

Re: 40m QRP Transmitter Success
Am having some success making contacts with the 49-er transceiver this evening due to the SKCC Weekend Sprint contest going on at the moment. Just to clarify the setup on this end, the 49-er is taking

Re: How do I power the 49er ?
My apologies to the group. It appears this thread has be hijacked to continue the discussion about the hiss issue I'm having with my 49-er. I have some additional information but I'll put it out on

Re: How do I power the 49er ?
Thanks, Dave. Well... that's exactly what I'm using - a 12 volt gel cell. Heavy bugger but it's working great. The radio itself is working perfectly. The rotary encoder is tuning as it should. 40m is

Re: How do I power the 49er ?
Aaron,? I am using a 12 volt gel cell battery to power my 49er and I'm using Yamaha CM-500 headphones.? I don't know if the earbuds would make a difference or not, but as Jack just said, wall warts

Re: How do I power the 49er ?
Sorry... forgot to answer that question. I'm using a 12v, 8aH battery. It's the same one I use when I take my other rigs portable. Aaron - N2HTL On Sat, Apr 9, 2016 at 10:32 PM, Jack Purdum

Re: Lead Free Soldering - Some lessons here may transfer over to building your circuits.
I'll second Jack's recommendation on the Radio Shack solder.? That is all I use on circuit boards.? It is great stuff.? If I ever run out, I may have to quit the hobby. Dave. W0DF

Re: How do I power the 49er ?
I have a Jetstream 30A power supply with adjustable output voltage. I run it at 13.8V for my 100W rig, but 12V for my Forty-9er. Wall warts can be very noisy and so can some cheap 12V supplies. If you

Re: Lead Free Soldering - Some lessons here may transfer over to building your circuits.
I never use lead-free solder. I prefer 62/36/2 in a .022" diameter (2% silver). It melts like a dream at low temps. Radio Shack carried it, but it's getting tough to find. I found 7 spools on eBay and

Re: How do I connect the rotary encoder ?
First, download Farrukh's document: http://www.farrukhzia.com/k2zia/dds-vfo-assembly-manual-rev2.pdf and look at the encoder on the schematic: 'D' on the schematic is the data line, or DT. Now follow

Re: How do I power the 49er ?
Hi Dave. Just disconnected the antenna and there's a lot of hiss on the output. Of course, the band is flooded with signals tonight due to the SKCC Weekend Sprint going on so it's much busier than it

Re: How do I power the 49er ?
Aaron, What does the audio sound like with the antenna disconnected?? Are you hearing 40 meter band noise, or are you hearing audio hiss from within the 49er circuitry. I have one working and it does

Hello Norbert. I'm glad you found the solution. Was just about to respond when I read your latest post. Glad you got it resolved. I was wondering if you could do me a small favor. Once you power up

Got it, in finding some minor differences between the instructions in the QST and Farruk's link. I re-read the whole thing and page 22 on the QST instructions clearly states; "12V power for the

Never mind, I found the answer to my question while reading another post. For some reason I wasn't clear after reading the QST instructions, figure A11. Switch: Pin 17 Clock: Pin 22 (D3) Data: Pin 18

How do I power the 49er ?
Hi! Quick question, I see pins 2 and 4 in the diagram to power the VFO board and I already tried it when calibrating the mini360 5V output. My question is how do I power the 49er ? Does it feed from
