Its fixed the wire d6 on raduino go via a resistor to c107 that I had correct I was unbalancing the mixer I was just outside the xtal filter so its all good now chris

I fixed it sifted CIO now getting 6w cw Chris

Not sure by your response, but is the other side of the resistor connected to +5 or ground? Vince. -- Michigan VHF Corp. http://www.nobucks.net/ http://www.CDupe.com/

Yep the other side is earth mine is bitx v3 paper work is for older bitx using 2 diodes ssb I get 6w on 60m chris

Dumb question. Are you on the right side of C107? What's the other side of the resistor hooked up to. Vince. -- Michigan VHF Corp. http://www.nobucks.net/ http://www.CDupe.com/

Hi all I am not getting any cw carrier generated I dropped the 10k resistor to 4.7 k hitting the key puts my radio into tx OK I am getting 213mv on c107 do I need more chris

Running behind on setup should be on air around 1:30-2pm est. I will not have wifi to update.

I'm in the queue with #595 (for 20 M)!

Banjaxed Raduino: can I buy a replacement? Populated PCB only, Display not needed. What price such a "partial kit" to NZ? I'd ask direct rather than through the Group if I could find an address

Too many bits and pieces lying around, and I think 12V from the PTT switch got into one of the Arduino pins and banjaxed it. I'd put the 10k B-E on the clamp transistor, but hadn't got to testing.

Hi Dale Sorry, just my mistake. You can have 593 for the other one. But it will ship together with 573 of course.? NOTE: support for the QCX transceiver kit is the QRP Labs groups.io...

150k to the 2N2222 base (mine's a 2SC945, again from that PSU) from +12V works to mute the audio. That, of course, is with the base otherwise open (and collecting RF!). i'll try 10k base to emitter

I ordered two units today (the other for a friend to help saving a few dollars on shipping) but only got one serial number, 573. Is that a serial number for the transaction or am I missing another

Agreed - not easy to fix. However, should be easy enough to mask. Gian, your 2-transistor 'clamp', applied to U1 pin 3, takes care of Rx-Tx transition, and I'm working on Tx-Rx with 10uF (what's to

It is a combination of power inrush and charging/discharging of the coupling cap between Mike amp collector and Rx audio amp input. ?Yes...not easy to fix._-_ Sent from my Verizon, Samsung Galaxy

Personal experience, I use them as my dedicated shipper now.. ?one order I had to be redone 4 time because they had lost it in transit by the 5th it finally made it to the customer, between the 400+

Hi Arv, Thanks a lot for the prompt reply. I did not follow the BITX20 project so I did not knw about the problem and measurement you did and reported. I guess the pulse was on the audio PA power
