- A simple SWR and RF Power meter module, designed to be built into an AM transmitter for monitoring SWR and to implement a high SWR cutoff. Video includes a demonstration, and description of the power mapping function in code. Schematic, code and more details at vk3hn.wordpress.com

Thanks for putting this together. For me, this is inspirational and motivating. Build instead of buy. Bought products often seem more "refined", which often makes them more appealing. Solving problems with brains and not money. I like this kind of content (I'm a minority it seems), and look forward to anything else you share.
I have always preferred to build something up than buying a product. That's what electronics is all about for me. But I am in a minority and I understand that most people want to buy rigs and tools and operate, or play with antennas, or chase DX. We are all different, and there is no 'better' or 'worse'. Enjoy whatever it is that engages you!
Complex project presented very well and complete. Thanks Paul!
Thanks. The complexity is mapping a raw analog reading from a diode RF probe to an approximation of the logarithmic power scale, without the usual AD8307 on the board. The polynomial equation fitting website did the heavy lifting. I am well aware that the mapping equation will only be usable over a narrow frequency range so it is not a good substitute for a true logarithmic detector. But in a single or two-band AM transmitter, it's fine. Cheers.
Congratulations Paul great project, very very good, I loved it, greetings Jesus.
Thanks agn!
Thanks
No worries!
For long range transmitter and receiver what thing is important?? - antenna OR circuit of transmitter and receiver OR frequency of transmitter and receiver??
All are important in different ways to allowing effective long range communication.
Very nice!
Thank you Mladen! Happy buiding and make a video when you get uSDX working. Cheers!
So many projects I want to start., but I have a Wah pedal with a worn out pot that needs attention for a recording session tomorrow evening
Wah Wah Wah Waaaa-hhh. Chris, where have ya been? I've missed ya. Conspicuous by your absence. Touring?
@@Paul_VK3HN oh I wish. In the studio this afternoon. Yay. No gigs, but I did put out a rework of a beer ad on my channel....if you’re old enough to watch it. Age restricted in a heartbeat :-)
@@MidlifeRenaissanceMan Bitter not get into politics I suppose. Is that you doing the voice over?
@@Paul_VK3HN yeah. I’ve tried to stay away from it too, but too hard to pass up when it comes to cheap laughs. Yup. That’s me, with a bit of multiband compression, and a hard limiter.
I’ve almost thrown together a couple of ham videos, but got distracted with other things. Might be time to jump in. Especially with the mag loop, the $10 QSO and the small back yard dual band vertical
Tem os código e manual

@@Paul_VK3HN obrigado amigao
First of all thank you for this video. Can i use it for ssb transceiver, because of very simple?
Yes you can.
@@Paul_VK3HN Ohh, i am so happy thank you again. Have a nice day.
amigo voce tem um email pra me ajuda .eu coloco pra gravar ta um erro ,Biblioteca inválida encontrada em C:\Users\berdiante\Documents\Arduino\libraries\TEA5767_Radio_UNO-master: no headers files (.h) found in C:\Users\berdiante\Documents\Arduino\libraries\TEA5767_Radio_UNO-master
grava so pela metade nao to entendendo nada me ajuda
@@JBSATE Olá amiga, very sorry but I am having some trouble with Portugese (?). It seems you may have Arduino library problems. I recommend you investigate your library and Arduino IDE installation before proceeding. If you have the libraries for a device such as the 7 segment LED displays, always run the example scripts first to make sure your library has installed correctly, your Arduino can talk to the display or other device, and do this for all devices your project interfaces to. Then you may make more progress with my script. Good luck!
