The mystery green board is a VSWR bridge. I bought it from kitsandparts Toroids, Ferrites, Parts, Kits, Toroid King, QRP Erector Set http://kitsandparts.com/ Toroids, Ferrites, Parts, Kits, Toroid

Hi. That's great news, any pictures ? I'm waiting for one more part to come in the mail and will be ready to finish mine. Keep us posted. 73s Norbert

Afternoon to all. With everything finally completed, I fired up the first prototype of the 40m QRP Transceiver with the DDS VFO and the 49-er. Happy to report that the unit is up and running. Receive

Dennis: It appears that there has been a change in the library. Try the attached version and see if it works for you with the I2C library. I can't do it right now as I loaned by Forty-9er to a friend.

The class name is capitalized, which is why you see the line: Rotary r = Rotary(2, 3); ? ? ? // Create encoder object and set the pins the rotary encoder uses. ?Must be interrupt pins. in the VFO

Jack, Now I am confused. The rotary library that came with the DDS-VFO is capitalized as is the include in the DDS into file. As is Brian Low’s include library. 73 Gary

You are still using the wrong encoder library. I know this because the include does not use a capital 'R' for the file; it should be lowercase 'r'. Delete the Rotary library that comes with the IDE

Gary, Thanks for going to the trouble of developing a wiring check sheet. I completed all of the tests and it all checks out. I still think this may be a sketch problem: the fact that when I download

Just got back. Been at my mountain property trying to get a cabin built. Will all that you suggest later today. Thanks for the input. To: SoftwareControlledHamRadio@... From:

I've already started it...that's where the photo came from (simulated data). Right now I have it working on a breadboard, but the new part of the circuit is on the homemade board you see in the photo.

Any thoughts to developing an antenna analyzer using the DDS VFO as the core of the analyzer?

Glad to see this up on the site...I'm sure it will be helpful. Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Wednesday, April 6, 2016 3:25 PM Subject: Re:

A continuity matrix for your encoder issue

Yeah, something strange has to be going on, but it's hard to tell what. Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Tuesday, April 5, 2016 10:00 PM Subject: Re:

Jack, I agree about your conclusion - I’m guessing bad connection or solder joint on the DDS VFO board. Just wanted to test the encoder separate from the DDS VFO to confirm it is okay and then point

FWIW: you shouldn't use a Serial.print() call in an ISR, since that method uses interrupts itself. Something is definitely out of whack here, since there are over a hundred of these boards out there

Dennis, Well I’m stumped then. Bye the way, I hooked up a bare encoder without the external pull-up resistors (that is what is on the pcb) and it worked fine. Can you load the example called

In case I did not mention it earlier, I tested the sw circuit with a DMM and pressing the switch sends D4 on the Nano to ground. Tomorrow, I am going to test the pulses with an oscilloscope. Dennis
