Hi Raj!
I already removed C91 and C92, output just jumped from 1W to 2W
arduino output is at 40mV at USB and zero at LSB even if its disconnected from the bitx board

Re: Rotary Encoder - Nut size?
Look at nuts on any cheap import small pot with
6mm shaft?

Re: Rotary Encoder - Nut size?
On mine,? OD is 6.75 mm.? Maybe 0.5 mm thread
pitch?
And yep, the picture shows NO Nut!? Nuts...to
them.

Remove C91 and C92 as combined they add a capacitance load of 500 pf across the Raduino output
and will cause a reduction of amplitude.

I already adjusted the output to 8mA for USB/LSB, is there any other way to increase the output?
thanks and 73!

hello friends!
Just an update
I did Jerry's tip of generating 7.150mhz at clk0 injected it at Q13 and I got almost 10w on dummy load (thanks Jerry/KE7ER!)
It seems the TX amp section (Q13-Q15) is working ok
Is the arduino's output at 40mVpp on LSB normal? and when I switch to USB i got no output
I already adjusted the output to 8mA for USB/LSB, is there any other way to increase the output??
thanks and 73!

First BITX to BITX contact...
I heard Tom VE3THR calling CQ on 7277 KHz at about
02:45 UTC... 19:45 Pacific / 22:45 Eastern. I gave Tom
a shout with a 100W rig and made contact and then changed
over to my BITX40. While I have made perhaps a dozen or
so contacts with the radio before (San Diego 1900 km was
my best DX previously) and I have made contact with BITX
radios on the other end a couple of times, this was my
very first BITX to BITX contact!
Needless to say, I was quite excited with this 3473 km
QSO. I was copying Tom quite easily most of time and gave
him a 3x3, but going by the 2x2 that he gave me and the
number of times I gave my call sign before making it a
confirmed contact, I don't think he was copying me as
well as I was copying him. I don't think we could have
exchanged much than the signal reports and call signs,
but VE3THR is in the log!
Thanks Tom for being my first BITX to BITX contact!

Tom, you were 59 here. I could not hear Keith but I heard you give him the report.?

Re: BITX QSO Night, Sunday, August 20, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
wow, just did a 2000 mile qso with ve7gdh Keith on bitx40...BARRIE ON to?SALT SPRING ISLAND, BC. That's a record distance for my bitx40. Sigs were only 2x2 but we did it.

Rotary Encoder - Nut size?

Re: BITX QSO Night, Sunday, August 20, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
Ed, you were really strong here. Easily 59. Hate that I missed the contact. I have some fine tuning to do on the whole station.?

Re: BITX QSO Night, Sunday, August 20, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
QSO with Bill N2CQR S9+
QSO with W1LY Willy 59 as always with a bit of QSB
Heard VE!BW? QSO with N2CQR

Join us as we make contacts from BITX40 to BITX40 on 7.277 MHz in 40 meters!
To participate, call CQ BITX at 7pm sharp, your local time, on Sunday. Repeat your CQ call on the quarter hour (every 15 minutes). It is helpful if you call CQ BITX with your name and location.? Repeat your call a number of times if conditions are weak.
This is a worldwide event starting at 7pm in each time zone. The band tends to improve as the night goes on, so please call CQ and monitor through the evening.?
Report your QSO's, discuss propagation, noise, signal reports, audio reports, antenna type, etc. in this thread.
This is an undirected, scheduled event.? The BITX QSO Night relies on you to call CQ BITX to initiate contacts with other stations, so warm up that final and transmit a few calls at 7pm on Sunday.? Talk to you then!

Re: BITX QSO Night, Sunday, August 20, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
I could hear?N2CQR. ?No complete QSO for me.?

Re: BITX QSO Night, Sunday, August 20, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
I'm guessing it was WB5YYM that called me. QRM and weak signal came
in strong enough to get Arkansas
only. I did hear part of the call sign. Later I heard both W1LY and
VE3THR, will try again later.

As of a few minutes
ago, BITX QSO night is no longer a spectator sport. Hope the
T-storms go away, and ?I don't get called in to work, as has been
the norm the last couple days

Re: BITX QSO Night, Sunday, August 20, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
OK Paul...just got your call and then QSB wiped you out. TNX for 5x5 you also were 5x5 then 0x1...got you in the log qso # 7
Had same trble with W1LY...5x5 then gone! ?very weird conditions tonight.
also worked KB0OVD Sean tonight.
haven't heard anybody else...got on about 0030 hrs tonight

Re: BITX QSO Night, Sunday, August 20, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
W1LY was strong for quite a while and I can still here him. Heard W0OIC and the station he talked to for quite a bit. Both strong. ?VE3THR is starting to come through the noise now. Hearing several people tonight.?

Re: BITX QSO Night, Sunday, August 20, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
Heard W1LY here in Kansas City but could not reach him.

Heard N2CQR, WA9DAH, W0OIC, W1LY, in Ottawa (quebec side). No-one seems to have heard me though. On a sloppy inverted V.
