BITX QSO Night, Sunday, November 12, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
Join us as we make contacts from BITX40 to BITX40 on 7.277 MHz in 40 meters!
This is a worldwide event for BITX40 stations starting at 7pm in each time zone. To participate, call CQ BITX on Sunday, starting at 7pm your local time. The BITX QSO Night continues through the evening and conditions usually improve after sunset, so it is worthwhile to participate later in the evening.
Suggested Best Operating Practices:
Work at QRP power levels unless conditions require more power.
Call and listen for CQ BITX on the hour and every quarter hour.
It is helpful if you call CQ BITX with your callsign, name and location.?
Repeat your callsign a number of times during your CQ BITX and during QSO's.
Start a QSO by confirming the callsign, location, name and signal report of the other operator.
Say the callsign, name and location of the other operator so others can hear.
If the frequency is busy, avoid long conversations.
After your initial QSO is complete, ask if there are any other stations who would like to contact.
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 on Sunday evening.? Talk to you then!

Hi John...only heard WB2BLJ calling CQ but no joy yet. Did hear someone else but very fast QSB and couldn't get a call - might end in an "A".

Busy updating my BitX to v. 1.27.1 and watching the Patriots vs Broncos. You must load a new library, "PinChangeinterrupts" to get v1.27.1 to upload. Go Pats,Willy W1LY

No joy tonight. Heard WB2BLJ, N2CQR and W0OIC. No response to my CQ's. At 0347 UTC the interference from 7.275 AM is totally wiping out 7.277 - 20 over S9 on my Kenwood rig. Same transmitter peaking 40 over on 7.275 AM. Hard to compete with 150 KW station - going QRT...73

I am QRT with my BITX-40 as I have only the original build configuration, because I am clueless on how to update the software.? One day, I'll get some help on this.? 73, Karl, KO8S (MI).

Unless, something broke or is defective you should have no problem using the radio as shipped.

Well Doug, I have been getting reports of distorted audio from stations that I have worked.? A friend, about 2 miles away, confirmed it on his Icom '706.? Also, I have to speak loudly and close to the mic element to get any output and when I do, I see the displayed frequency digits jump about.? All of the radio has the original components with the only mod being for a RX/TX LED and two switches added to stop the "runaway" at the end of tuning pot rotation.? That is where I am at on this point.? I built two of these radios, gave one to my same friend, and he has the same problem as well.? I listen to his audio, and I can barely make him out!? So, the radios sit on a shelf.? Thanks for your posting too.? 73, Karl, KO8S (MI)?

Karl, when you come over, bring them both.

I assume you have a good stiff 12v supply.
If the VFO is jumping around, you might be missing the 0.1uF cap from tuning pot wiper pin to ground.
Best is one cap at the pot and another at the raduino end of those two wires.
Also, keep those three wires short, perhaps even use coax for the wiper pin plus ground wires.
Updating the firmware will also help, as Allard samples the tuning pot many many times and takes an average.
He also ignores the tuning pot during transmissions, so the VFO is guaranteed to stay put.

Karl,
Check your final bias.. too low bias and it will distort.

Thanks Raj, I will check the final bias setting, 73, Karl
