Anxious to find the answer. A recent post said it should be small (forgot value), but I've found that max power output is when it's cranked up max to 4vp-p. On Aug 27, 2016 10:41 PM, "Marty Boroff

Someone very kindly provided step by step instructions for calibrating the 49'er VFO which I followed faithfully when I completed my VFO kit. I lowered the peak to peak voltage as low as I could when

I am in the process of putting parts on the board and noticed that there is an extra resistor on the ver2.1 board next to the C8 capacitor. The board indicates it to be a 1Meg. I have not been able to

To those whose are interested, I have uploaded the keyer mod to the Files section. Detailed instructions can be found in the comments at the beginning of the file. 73s, Chuck WB6GPO

Thanks for your help Marc, I'll take a look and let you know how I get on. 73's Mike G4MFN

Thanks for the info on switching out Q6 (8050) for a 2N3904, Marc. Have done that and Q6 works cooler now. Interesting the 8050 must have been cheaper as the 2n3904 is a very commonly used device.

Just a quick correction, my call is W2ROW not K2ROW. It happens that K2ROW is my XYL but it was I who did the mod :-) As near as I can tell, the original 49er design did have offset built in but that

Mike: I suggest that you look at the very fine software modification for Rx offset from K2ROW in this group's Files section. The original software did not allow for a very effective offset on

Yes. I did mean collector of Q6. I hate when typos sneak in. 72, Marc N4DR

I would be interested in looking at your keyer software mod. Dave Fine, W0DF

I've never actually sat down and calculated the power consumed by the 49er in transmit mode, but I would think that supply would work fine. If anyone has the actual current draw, I think all of us

I picked up a small wall mount supply 12VDC 860ma, is this sufficient to drive the 49er and the VFO circuits. I am pretty sure I will be fine on the 49er, but don't know what the VFO boards will draw.

Hi, I wonder if anybody out there can help, I'm pulling my hair out here and I've not much left! I've built the DDS VFO which appeared to work fine with a nice stable output on J3 when I looked on the

Hi Karl, I'm not sure if merging two pieces of open source software together merits publishing in QST! But if there is interest, I can upload the code to the Files section. Needs a little cleanup

Hi Jack, I have purchased your book and Glen's book, and both are excellent resources. Problem is, there just isn't enough time to build all the cool projects! I do like to study the code, though. One
