Steve, that diode will only pass 1 amp of current. It will not work correctly if installed in series. You would need something that will pass 3 or more amps to work correctly. Don't forget to take

Hi gang.? I'm planning to install the diode in series with the V+ and then a fuse.? I only have a 1N5819 in hand.? I searched the data sheets for this compared to the 1N4002(7), and, even though I

One other thing I forgot to mention above - the need for squeeky clean key contacts or electronic conditioning of the inputs by using FET's has been made obsolete with this keyer version.? Since we

Is 7277 becoming a 'BITX frequency'? If so, I'll hang out there. I don't have one "YET"...... Dave -

Copping N4DR here in Western Kentucky. My BITX40 is receive only. Need to get it finished to transmit. Denis, WB8SKP

Hi gang, Ron, W2CTX and I (W0EB) have been steadily working on fixing some of the CW problems with the uBITX software and also changing the tuning over from the accelerated tuning for band change,

not a peep up here anyone anything anywhere!? listening 277 and 278

Me too! Hear someone very faintly right at the noise level. -- John - WA2FZW

Here in mid-west look for us on 7178 and 7278. South of the border stations on 7177 and strong carrier on 7277.

Broken mini USB port on the left. Salvaged, prosthetic mini USB port on the right. Will post results... Bernie, KC9SGV Sent from my iPhone

Well worked a few stations even a new General *KJ4TJZ ( http://www.qrz.com/db/KJ4TJZ ) /AG Larry in VA* Also got K9ABL David in KY I will try and get back on for the 7pm but might be a bit

Not hear any stateside on 40m i did try contact with W1NA on 3,799 MHz with my bitx on 80m with 10w but I not make it Chris G0WFH

Thanks to all the responders. I found a hardware problem...mmm The mini USB on the Raduino shows one pin bent back inside the casing. Tried to salvage it with a dentist pick.... No joy. Now I am

In the IDE you have selected Arduino Nano, of course, but are you sure you identified the correct COM port for the Raduino? Since nothing showed up indicating that it was that port on my system, I

HI Group. I am about to install an SSM2167 Pre-amp, Should I remove the bias resistor R60(4.7k) and then re-install post amp at say a 2.2k for the lower 5V the amp uses? IIRC, the SSM2167 Spec

I used this paper. https://www.amazon.com/Circuit-Board-Thermal-Transfer-Special/dp/B01CGRL2G0/ You print the image in reverse to scale on that stuff, iron it to the copper clad, and then soak in

David N8DAH can just make you out about 2x3 at best. Heard K9ABL much better. Poor east west prop right now from Barrie.

So, finally I did it - BITX40, diode D& blown (nice light and smoke) It is "off the shelf" radio - I made it few months ago - and now I take it to upgrade software etc.. Power on - and smoke. but
