Dear Charlie, Somehow RU-vid removed you from my 'Notifications' but I picked up a later video dated today in my feed. Anyway, very happy to have you back and very much hope you're both doing well and feel inspired to make and share projects with us. Just want to say in your absensent that I have been making good use of your archives and so glad we may see you add to them. Anyway thanks so much and 73 from the States!
Great to have you back! The future projects sound great. I have the low cost Chinese auto tuner, never thought about moving to the LCD display to cure the noise.
WOW! So glad to see you're back. Your videos were an important inspiration for me when I was especially down about whether I'd ever understand any of this stuff. I'm pretty sure it's entirely your fault that I'm still trying to build radios (and somewhat more successfully!).
Great to have you back Charlie, you have some fantastic projects for the future. I'm very interested in the ATU, so looking forwards to the design and build. 73's
Very glad to see you back and Ok, I'm not the only one to wonder if all was well with you. Looking forward to seeing and hearing of your next projects. Best 73, Ace
Charlie, I'm very happy to see you back. I'm looking forward to seeing you using the spectrum analyzer in your projects. I purchased one to use in my receiver projects and discovered I really need help in figuring out techniques on how to best use it. You are an inspiration.
Good to see you back in action Charlie. I found the transition to a paddle very hard but I think I am getting there. Lots of practice with a Palm Paddle and more recently with a heavier bench paddle. There are some nice 3D printed keys around, no need to mortgage the house to get a shiny Italian job, unless you want to!
Welcome back. I have been looking forward to your return and putting my Siglent Scope and AWG to better use. Your projects inspired me to purchase the Siglent kit. Graham ZL1GH
Nice to hear from you! Can't wait to see what is to come! You could disable the charge pump of the OLED to remove most if not all RF noise. Also, You got me to try to homebrew and Id love for you to take a look at it once it's all done. Let me know
Welcome back Charlie! You've certainly been missed. Glad to hear that you've got set up in your new QTH. Looking forward to following your upcoming projects. 73 my friend, Nick M0NTV
@@CharlieMorrisZL2CTM Thanks. I've just (finally) finished a 17m SSB rig that puts out a bit more power (65W). All I need now are some stations to talk to! Great to have you back. 73 Nick
Charlie, Glad to see you are posting projects again. I really have learned a lot from your work and look forward to every one of them. I have successfully built the SI5452 VFO using your software, but with the project on the DSB 80/40 rig you did 2 years ago, I am experiencing some minor trouble. The LCD display gives me the proper freq and callsign, but also adds "? 0 0? __ _" I have not been able to find where this is coming from. Any suggestions would be appreciated. 73 Bill, AB5XQ
Hmmm. That's interesting. Try loading in an example sketch from your display library and make sure everything is ok. If so, then look at my sketch and see if you can see any differences in the syntax.
So glad you're back; it made my day when I saw your new video. I'm building the T41 DSP radio now, and it calls for relays that cost ~$4 each at Digikey, but the ATU 100 you built and the relay board you have use relays that cost like $0.35. I'd be interested if you did some characterization of losses, or distortion, caused by the cheap relays in your tuner project, to see if there is a reason to spend the bucks for a relay with a datasheet. Thanks, Kevin NY3F
Hi Charles glad to see your video today! I was wondering about you. Congratulations on the new QTH and new shack. I would love to rework one of those ATUs with a 2x16 lcd because I can’t hardly see the OLED ones. Good to know about the noise generated by the OLED. I would like to make it look military style with protection handles with the ability to run on internal batteries. Plus ability to operate between 32-18 with is the voltage most US military equipment must be able to operate at. Just for fun and learn you understand I know. Glad you are doing well 73’s Don
I had to buy a Microchip programmer (www.aliexpress.com/item/1005003469083787.html?spm=a2g0o.order_list.0.0.6eec18026MhXWb). The ATU instructions include details on how to reprogram it for different displays.
Hi Charlie, I’d strongly recommend the twin paddle keyer over a single paddle even though there’s only 8 (I think) characters that use it. It’ll be harder to convert to twin from single. There’s plenty of sketches out there for them too so no point in reinventing the wheel.
I hear you Mark. I've looked at lots of videos and put some thought into it. Right or wrong, I'll probably go with the single paddle for now. I hope you'll forgive me!
Hello Charlie, it´s very nice that you find the time to come back on RU-vid. Hope all is OK with you and you family ?? I am very interested about your common new projects. Take care and have a nice Time. Best 73 de DB9FQ C31KM
It's been pretty quiet. But some other channels have continued to make reference to your work while you were gone, and I suspect they are going to be quite pleased you are back so they can get some new material to reference and link to. :)
Nice to see you back Charlie. Please can you help me build a vfo? I have an arduino, an Si5351 pcb and an oled display. I've constructed loads of vcxo transceivers successfully but this arduino stuff is a 'black art' to me! Vy 73, Chris G0VOE, Somerset, England.
Hi Chris, I'm aged 77 and a refugee from the analog world. I've also built many qrp xcvrs and am also trying to get to grips with this Arduino, Si5351 stuff to replace LC/ varicap local oscillators. The hardware looks simple enough - the problem `I have is the material on the software is clearly written by people with an IT/ programming background. I would welcome material to help folks like us. 73, Mike , Trier, Germany
@@mfwwhelan7561 Agreed Mike. I too have no problem with the hardware. I'm a youngster at 65, my first radios were converted pmr rockbound sets with just a couple of frequencies!
