Thank you all for your replies.Unfortunately, I obtained my licence (VE3DLG) in 1963.? The test was entirely on vacuum tubes.? I have not kept up with solid state technology and at 83 years of age,

Look at the pot after Q90. It allow to set output to almost zere.

Jerry, thanks again for your input. The project went over my head so I decided to choose the easier path and ordered an AGC board from kit-projects.com: The installation was quite easy and everything

What I would try Vic is remove the SMD and put back a leaded one and see. If the power comes back up then the SMD ones must be fake. All depends from where you got them! Raj

Thanks, Evan, I'll be looking there. The drop in power occurs with both CW and steady tones on SSB on all bands compared to previous records I had when trying to figure why 40m CW was oddly low. I'll

For sale. ?Bitx V3 Ser No. *∩* 0219/4 . Unassembled as purchased in original shipment case. Audio chip is not the problematic WX brand TDA2822. Included are the assembled but not installed K5BCQ

Hi Vic, I would check that C81, R83, and the traces around them did not get damaged.? The RC combination is used to boost the gain at higher frequencies. Also, can you confirm that you made the power

Although I had leaded components for the Q90 3904 transistor and R82 100 ohm resistor that both failed, I waited to get some SMD devices thinking they might be easier to install, and not very

What is the current value of pre v6 raduinos?? I have one.. was thinking of making a reciever with it but would be willing to part with it .. Reply to email if you wish kd9mdl@...

If you get a replacement I wouldn't mind grabbing your old one for a few bucks to desolder and add an upgrade to.

Hi, Pkease try with www.lioncircuits.com ( http://www.lioncircuits.com ) It is located at bangaluru, south india I hade got few pcbs through them. Almost similar to jlc pcb All the best Regards Sarma

Are there and recommendations for PCB houses in India for prototype and <500 pc. board quantities? Thank you...

Besides the uBitX and the BitX40 that I use routinely and are finished and mounted in cases, I have an old "parts" BitX 40 and a never-installed Raduino so I was building a rig for a friend to be

Hello, I think I found what I wanted. You can do one with various modules that you can easily find Seen on the HBFE group /g/HBTE/filessearch?q=tinysa The title is a bit misleading

I'm selling my uBITX V3 and V4, both with Nextion display and KD8CEC firmware.? Fully assembled with aluminum enclosure, working. uBITX V3.0 with Nextion 3" TFT and KD8CEC Firmware Fully Assembled

Thank you, David, for taking the time to study this. As Arv referred me to the HBTE forum, I think there are more "contentporary" examples than this one which dates back to 2010. I will look closely

Taken at face value, the question looks like it is asking for a transformer to match impedances at 433.9MHz My electronics knowledge comes from an aged mechanical engineering background and the only

Justin answered your question on the supply voltage.? For the v6 I would not go much above the nominal 13.8 volts.? The 5volt regulator can get really hot above that and shut down. As to your

Gerry - I have been using mine for 5 months without issue and it's always been on 13.8V. 73, Justin B. KI5GKD

I have a couple of questions about the 'V6.? I recently got one and assembled it, but I haven't powered it yet. 1st question - can the radio safely be powered from a 13.8 volt supply? 2nd question -
