Hi Jim I would like to hve the scope.. how to contact you directly? bobbie kd4lv bob4john@windstream dot net

Karl, I put a very small series resistor in the D882 emitter leg to calm it down. Still getting 2.5wts out into the dummy load. I also put a good chunk of aluminium for a heat sink on the D882s

Thanks Jim for the encouraging words!? Until the 49-er/VFO article appeared in QST, I had never heard of a "sketch" either!? I had heard of the Arduino, but I just assumed that this was some kind of

Hi Jack, No, 200-300mV p-p is the data sheet specified input signal amlitude pin 6 of the NE612 wants to see from the external VFO, in this case, the Nano DDS VFO output. Afterall, the output of the

Hi Karl, I too, had never dealt with Arduino programs, (what's this 'sketch' stuff anyway?! ;) Jack helped me with that and I was able to upload and even change the the program to zero the DDS VFO

Bob: As you know, I'm a software guy, but given what you've detailed, it sure sounds like a bad DDS board. If you socketed the DDS board on the two rigs, swap out the boards and see if the "good" rig

Hi all.. I built two of the QST version of the 49er by Jack et al .. the first one wroks great, the second one will not transmit and there is no sidetone. The display looks correct and the rotor

Hi Karl: Glad that someone jumped in to help you. Unfortunately, the Arduino Integrated Development Environment (IDE) has to follow a fairly strict disk layout for the compiler to find what it needs

Some posts back to this forum, I posted a topic indicating I needed help programing my Arduino Nano with the required files for this 49-er VFO project. This requirement, had me baffled! Setting up

How can one convert the 49er+VFO kit for 20 or 17 meters? Is it just a matter of using a different value combination of Lx and Cx Fig A2 (page 6) of Jack's Assembly Instruction Manual? If so, what are

Thanks, Dennis, for the personal touch. I moved to SIicon Valley 5 years ago and attended MakerFaire 2 years in a row. I shall return, but this year I went on a ham radio vacation to Jalama Beach

All: You may note realize it but Dennis is the brains behind the ham radio projects that appear in the book. Years ago I co-authored another book and vowed never to co-author again. I am so glad I

Bob, Do you ever get to Maker Faire in San Mateo?? For about six years we have been presenting "Not Your Grandpa's Ham Radio" there.? Maybe you've been by our booth??? If you HAVEN'T been to the

Nice work. Thanks for all your efforts of evangelizing Arduinos for hams. Next month I will give a talk on the Forty-9er here in Silicon Valley. Bob

I just posted a photo of the Beta AA. Jck, W8TEE

Bob: That's the same case I used for the Beta version of my Antenna Analyzer. They are nice and they also have a rubber gasket seal on them. Jack, W8TEE To: SoftwareControlledHamRadio@...

For mine, I used Jameco.com part 141841. It is an ABS case with a clear top. For drilling holes I used an Irwin step drill bit and the plastic was a pleasure to pierce. Bob KF6ABC Mix

A number of readers of the QST article wrote and asked where I got the acrylic case. Alas, Amazon is no longer carrying the case and I could not find a supplier who would sell in less than quantity

Thanks, Daniel. I hope you're having fun with the 49er! Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Tuesday, August 2, 2016 2:42 PM Subject: Re: [SoftwareControlledHamRadio]
