Re: Cw carrier no rf out

chris gress
 

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?

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

OOPS! Question for Farhan ...

 

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 ...

Re: I7SWX PTT Pop Mute

 

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. Looks like a new Raduino needed. Display seems OK.
TTFN, 73!

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... see?/g/qrplabs

Re: I7SWX PTT Pop Mute

 

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 ... after tea :)
Meanwhile I note quite a bit of audio hiss - worsening with proximity to the board, and particularly bad by touching the filter xtal cans. Can they be earthed without altering the filter too much? Might give better RF immunity if, like me, your unit is 'al fresco' or in a non-shielding enclosure.

Re: I7SWX PTT Pop Mute

 

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 hand) between +12 and junction of 10k/1N4148. If that 'hang' is not long enough (T=CR, uF*k = ms, 10*10=100ms - will that tenth of a second be too much? Lessee, have I got a smaller cap?) I'm sure the 10k could go to 47 or even 100k and still clamp effectively - do we really need (10V/10k=)1mA into either base? There's a couple of 150k still on that scrapped PC PSU .... We shall see ...

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.

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 line, right? You are right, it may be a complicated to find a solution.
I will try to think ... hi.

Re: Delivery times to Canada

 

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+ orders that go out a week I know the following week there will be 20+ lost. In my opinion the ten dollars for DHL is well worth it.
