Re: Low Audio, CP2 Proximity sensitivity
Thanks Jack, I pulled the LM386 and checked all the connections then reseated the chip.. As a backup I just ordered a couple and then I'll know if that is part of this. I don't know about the NE612

Re: Low Audio, CP2 Proximity sensitivity
Well, it was just a thought. I checked my 49-er and there is no signal affect when I get near or touch CP2. Have you changed the LM386 to see if it's bad? ALso, have you done continuity checks to the

Re: Low Audio, CP2 Proximity sensitivity
Jack, I checked CP2, and all the others and their installed correctly.. Neg side to the hatching marks in all cases (right ones too). The level remains at one level..Just enough to hear the SG tone.

Re: Low Audio, CP2 Proximity sensitivity
CP2 is part of the audio amp. Is there any chance you have the polarity reversed? Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Saturday, April 23, 2016 12:47 PM Subject:

Low Audio, CP2 Proximity sensitivity
This is a corrected message.. Disregard my previous... Hi all, After connecting and powering up the 49'r and dds-vfo combo I've discovered a problem... Been checking out an issue with very low audio

Re: winding torrids and red wine don't mix
No, I followed what you were saying, but the 12V does stress the voltage regulators that are on board. Yeah, memorizing is a lot different than learning. Jack, W8TEE To:

Re: QRP Quarterly Article
I don't have my copy yet, but good to know it's out. Actually, when I get the software done for the antenna analyzer, I'll integrate that into the 49er and post the file. My guess is Tuesday of next

QRP Quarterly Article
Nice article in the new issue of QRP Quarterly, Jack. Where do we slip that code into the 49er project code to take advantage of the quick QSY feature. Dave, W0DF

Re: winding torrids and red wine don't mix
Hi Jack... and thanks for the reply. Just so there's no confusion, the Mini-360 bucking module has indeed been adjusted for a solid 5v as per Farrukh's instructions. The "issue" I was having - if you

Re: winding torrids and red wine don't mix
Aaron: The rig is really rated at a max of 3W, not 5W. I would encourage you to limit the input voltage to the rig at 12V and adjust the VFO board for 5V per Farrukh's instructions. Adjust so output

Re: winding torrids and red wine don't mix
Hi Don. Dennis already responded to the coil issue you were having so I won't tie up the thread with that. I'm curious though how you happened to fry the D882. As I mentioned in an earlier thread, I

Re: winding torrids and red wine don't mix
Hi, Don Nope, you have one extra turn on each coil.? Each time the wire passes through the core counts as a turn.? 12 passes through the core means 12 turns. Hopefully that will help clarify the

winding torrids and red wine don't mix
OK so my 49'er is deaf...worse than me (double hearing aids)...takes about 1 millivolt out of my Wavetek SG to hear anything worth listening to.....(like a Hallicrafters S-120 with low line voltage.)

Re: Setting the voltage on the Mini-360 regulator
Pins 8-10 should all be +5V, while 3-6 are GND. Pins 1 and 2 should be +12V with respect to GND. The fact that you do not see 12V on pin 2(+) and 4(-) makes me wonder about the external power supply.
