@David: this morning, I completed the video's of my 6 mtr transceiver. Hopefully you find enough information in the schematics that I included. Because the output is not as high as I wanted, I made an

Last weekend, the IARU R1 50 MHz contest took place and I thought it was a nice moment to show the performance of my 6 mtr transceiver as well as the activity. I made a small video about this: https:/

Thanks, however, alle credits to you Ashar! Torroids I used are in the bandpassfilter but could of course also be done without toroid core. 50 MHz are not too many windings. The IF is 12 MHz. Activity

Thank you for your kind words. It is all experimental, no kit or so. In fact, it was the intention to change some modules afterwards but still not needed. Parts of schematics will be shown in the vide

Chris, You have made a wonderful radio! Did you find any opening on 50 MHz of late? You must add CW to it. It would be interesting to see the complete schematic. It appears that you didn't use any tor

Chris van den Berg, Love the copper board and how you brought the wiring from the board thru the bottom. very clean looking too.Are you planning on a kit for this unit or its a one of a kind? You ment

Starting with the ideas of the original BITX concept; I made this transceiver for the 6 mtr band with components that I had laying around but also some ready purchased modules with easy construction t

Hi folks, If you missed the excellent talk by Don Field G3XTT (editor of Practical Wireless) on "The Magic Band", then you can catch up, and watch on YouTube: https://www.youtube.com/watch?v=TVJDWJwOm

I have a spare bitx40. I also have other 40m qrp portable radios cw and ssb. Id like to get on 2m ssb/cw. I do not have a 10m rig. The choice is to either mod the transverter to use a 7mhz transceiver

#bitx40 #6meters

The problem is that the Bitx40 (as referenced in the subject of this thread) only does 40m, so a transverter with a 28MHz IF would not work.

#bitx40 #6meters

Why? Whats the problem with 28MHz?

#bitx40 #6meters

Use the Unranian xvrrts at 28 MHz

#bitx40 #6meters

Would 7mhz be too low as an IF for a transverter for 2m? What about 6m? Im thinking 130mhz (LO - IF) might be too close to desired RF of 144. 14MHZ separation at 144mhz only 10% difference. Obviously

Peter, First ditch the 3904s or the similar parts used are near dead at 6M and forget 2M as the layout is unfriendly to VHF there. You will need a bandpass filter at 50Mhz. A dds generally doesn't rea

#bitx40 #6meters

We've had some discussion about moving the uBitx up into VHF. Conclusion seemed to be that the best bet would be to run it at 30mhz and use one of the Ukranian transverters. The FM thing came up then,

#bitx40 #6meters

Not a trivial hack. I'd suspect you are replacing the first mixer, the bidi RF amp in front of that, the 7mhz BPF, the entire transmit amplifier chain including silicon and transformers, and the outpu
