Re: Deleting the truth.
I am deeply saddened by all the negative, and hateful comments. I appreciate What ?Farhan is doing. I like the product as a whole. But the community kept asking for more clarification of the problem and it escalated out of control. And as for the technical, ???Joel Caulkins?pointed out an error about the brown wire for calibration actually being the red one. As per the schematic. This is a helpful comment. |
Re: Info a out buying BITX40
¿ªÔÆÌåÓýSara On your first question, once you have a Paypal account, Paypal knows your shipping address and will use that as the default, although you have the opportunity to change that address for every order. You can also send the seller a message when completing the Paypal transaction. On your second question, HFsigs will send you an email once your order is on the way via India Post. They will also give you an India Post tracking number. The price declared for customs purposes was the purchase price, USD $59, in my case. 73 Bill, VK7MX On 26/01/2017 3:02 PM,

Re: My BITX40 On The Air Experience
¿ªÔÆÌåÓýRandy, Looks Great. Proves that anything can be used to house these BITX in or On.? Can¡¯t wait for the video ? From: [email protected] [mailto:[email protected]] On Behalf Of Randy Hall ? Hi With so many technical messages flowing on the list I thought I would describe my BITX40 experience. I now have it put together and operating. My BITX worked the?first time I turned it on. No problems. I finished up the wiring Saturday afternoon. I was tuning around the band, and it sounded like a contest was in full swing. Working QRP during a contest can be a challenge. It was the North American QSO party. One of the nice things about this contest is that 100 watts is pretty much the power limit. This helps our QRP signals have a chance on the band. Being a QRP station during a contest means, you will be giving your call our many times. Many repeats on callsign and exchange. But, the other station will usually work with you as he wants the point. I tuned around for looking for the strong stations to contact. Over a couple of hours I worked: K0IP John ID W1RH Bob CA K7LVJ John WA N7MZ John WA K0SN Tom MT K9CT Craig IL WN6K Paul CA I was really amazed that I worked all these stations from this little board sitting on my bench. Using 13.6 V DC I was getting about 4.5 watts out, as shown on my LP-100A meter. My antenna is a PAR end fed quad band 40/20/15/10 at about 15/20 feet. My location is Gold Beach Or CN72. The Raduino?tuning kind of drove me crazy. I would be tuning for a station. I would not know that I was reaching the end of the pot, and it would take off tuning automatically. I really had to watch the display to see where I was so that I could tune back the other direction to try and find the station again. I understand that this is the normal operation.I may try tweaking the sketch for the frequency change amount and speed. After all, experimenting is what the BITX is all about. I should have a video of a bit of the wiring and operating the radio in the contest next week, Feb 1, on Ham Nation. And then on my YouTube channel. Farhan, thanks for the hours of fun. Have fun and be radio active, Randy, K7AGE ? |

Re: Calibrate Lead Confirmation
¿ªÔÆÌåÓýMy brown wire did not put mine into calibration. I saw the post
yesterday and used the red wire and it went into calibration
properly. Both wires are inputs, so grounding either one will not
cause any problem. I have had mine up for about 10 days now and have been well
pleased with it. You do have to work harder to get a qso bit it is
very satisfying when you get in with 6 watts. On 1/26/2017 11:59 AM, Ion Petroianu

Calibrate Lead Confirmation
Jim Schliestett
¿ªÔÆÌåÓý? According to the BitX40 web pages, the brown lead of the Raduino 8 pin connector is the calibrate lead. I thought I saw a post that referred to the red lead as the calibrate lead. I want to be sure before I wire it out. Is it brown or red and which pin on the Arduino_Uno is the calibrate pin, A2? Thanks. |

Re: Deleting the truth.
i am not at all suggesting to boot anyone out. on the contrary, hfsignals should clearly communicate that they should be directly written to for commercial stuff and tech discussion should be on the group. thanks all for the kinf words. i am only an editor of sorts, rolling things into the bitx. sarma has suggested that the lcd light led should be taken off the regulator and fed from 12v through a drop resistor. this will help in reducing the power dissipation of the 5v regulator which can be moved to smd format. he has suggested several other changes too, including use of BAT54s for the modulator. suggestions like this take a long time to show up as the layout to shipped board cycle is 8 weeks long. keep the suggestions flowing guys.. john, I understand the confusion but we had to pull the plug on the raduino upgrades. - f On 26-Jan-2017 8:55 pm, "Jack Purdum via Groups.Io" <econjack=[email protected]> wrote:
