Hi Charlie! A work of art. That's what your beautiful layout looks like. It's like seeing the innards of electronics working! Fantastic stuff to learn and to teach. Terrific work. De VU2RJV handle Rajaram from India.
What a nice build, Really Great ssb Radio. Hope all works well, I wish I was able to build this but being almost Blind and in my 60's won't happen, God Bless
I like that you resisted going the Arduino "menu" route and rely instead on rotary and toggle switches for your inputs. Menus may be necessary for portable rigs owing to limited front-panel space, but they're a totally-unnecessary bother for a stay-at-home rig. --Todd K7TFC
Hi another great video, thank you very much .... but I think at SSB the Bfo = Fop + Cf - 2400/2 - 300 and the Vfo= Cf + Fop , another thing to mention about cw from compatibility point it is usually an lsb signal and the screen show the carrier freq. not the tone freq. I think that will eliminate some confusion at some point when working some stations on cw .... keep the good work and looking forward for the next video
Thanks for the input. My approach is to have the display show the actual CW freq. I will adjust the TX software to ensure my CW signal goes out on exactly the same freq. I did that for the tramping CW rig and it worked well. Thanks again and 73.
Hi Charlie. Great video series, I have learnt a great deal from watching, many thanks. One thing I'm not clear about, what does the A/B switch do, is this to switch between CW and SSB?
@@CharlieMorrisZL2CTM If running into a high resistance load DC coupling is OK, but with low resistance loads DC current is shunted towards the low resistance path via the Si5351 internals. A small improvement in Phase Noise gained. See QRPlabs phase noise article
Hi Charlie, thanks for your videos. I always learn something new ! Question, is the output of the Si5351 filtered? It seems to be fed directly to the diode ring mixer? I could not find anything in the blog regard this. Thanks for sharing all of this!
Hello Charlie , Great video as always keep them coming we really do appreciate your efforts. What is the model of your sig gen? A siglent by the looks.
Charlie, Could you please identify the black stubby item attached to the Siglent AWG used for the CW test. I should like to get one to use with my own SDG 1032X for the same purpose. Graham, ZL1GH
Hey Charlie, another great video cheers - I lashed up some software to do the Transformer calculations just to simplify the repetitive calculations and I was wondering if you'd like a copy to have a play around with and see if you can break it, just before I release it to the wiser world. Cheers Rob M0XXQ
No Chris. I did have a think about using varacter diodes, but elected to have two filters. I wasn't sure if I would still have to have two different terminating resistances to get the right passbands. I really should give it a go as an experiment.
Saya juga pencinta oprek radio suka dengan orang luar negri alat alatnya lengkap semua.tapi saya kadang nonton youtubnya Marconi Poncol Disitu membahas Radio Ombrow AM PWM dan buka chanel Bank Canare Ombrow disitu belajar Fm/Am dan perakitan TX RX.Salam radio master
Hi Charlie, I've seen some of your videos and after looking at another QRP (based on Arduino) I got the NEEEEEED to build also one for myself (I have experience building and programming arduinos, esp32, raspberry and also tube amplifiers and guitar stomp boxes) but I don't now where to get info on schematics and their BOM to start. could you help me by pointing for what to look and study?
