Glenn, I took a look at my PE4302 module. It is different than the one you are looking at.?? Bad photo attached. It was the cheapest one I could find, seems to work fine though. 73, Gary WB6OGD

When I start Erik's Windows app,? it sometimes says "sweeper not found" or the box only has "mockup" but when the main window comes up, just go to "Connect" and then the COM port shows up, click it

Jerry, Gary & Bo, Thanks for the responses - much appreciated. While I did a lot of checkout of the Nano when I did the mod to it to ensure it was worthy of being installed in the setup. I do have to

If you have a junkbox full of Nanos, I say go for it. It's a hobby. Many have hacked the Nano for 3.3v, most web reports state it works just fine at 16mhz. Saw one report that it worked better at 3.3v

Hi Please be aware that the Atmega328 is operated beyond specifications, 8161D–AVR–10/09 section 28.3 Speed Grades, when subject to 3,3 V and a 16 MHz clock. Between 2,7 V and 4,5 V the slope is

Marty, as I mentioned in my post, the wiring information is in the comments section at the top of the code.: -- Joerg, ex-DB2OO

Yes Marty, Mine communicates and programs fine on 3.3v, you must have something wrong. I used the very common 4 channel level shifter board from ebay. Just search for “4 channel level shifter”. It

Could you reliably download to the Nano before you did the surgery? Have you tied the old 3.3v and old 5.0v (now 3.3v) rails together? Have you measured the output of the 3.3v regulator, verified it

Gary, Real quick - which level shifters did you use for your setup on the Nano? Please let me know the vendor and part number at your soonest, and also let me know how you implemented them in your

*PLEASE DISREGARD THIS ORIGINAL MESSAGE AND SEE THE MESSAGE POSTED ON 2/18 FOR MORE INFO.* TinySA Team, Today, I took a programmed Arduino Nano (with TinySA for the Nano) and performed the 'surgery'

Joerg, MANY THANKS for the code upload...I GREATLY appreciate it. I'll try programming the 'Blue Pill' tomorrow night - I'm too burned out programming boards yesterday and building the 432 MHz

Great call, I've been thinking about this recently (along with coupling to prevent adverse signal effect) and also wondering about the other way around for tapping the signal to perform demodulation

An offshoot of this project could possibly be a *simple Panadapter.* With a TFT display and modified sketch to sweep either side of a defined frequency (ie the IF of the associated Transceiver) plus a

I'm thinking to make a PCB for the tinySA but don't have the PE4302 attenuator module yet. I have most all the other parts but need some dimensions of the Attenuator from eBay to speed things up. I

Joerg, In signal generator mode "P6 3", what is normally the receive Si4432 is now transmitting. It transmits directly into the SAW filter, not attenuated by the mixer. Some SAW filters such as the

One additional info: The LO output power is set to 20dBm, I.e. you need to have a 6dB attenuator with a ADE-25MH mixer, and 13dB attenuator with a ADE-1 mixer between the TX module output and the

Marty, as promised, I have uploaded my modfied TinySA code to the Files section into a new folder TinySA ex_DB2OO. This code compiles (tested on Arduino IDE 1.8.10) und runs fine on * Arduino Nano

I believe Erik has rotary encoder support already in TinySA.ino for the tiny 0.96" OLED display he used. I haven't tried that. Jerry AC9NM

I have a hard enough time with the touch screen on my phone and even more so on the (small display) NanoVNA! I prefer using an encoder for menu selection. You might want to look at another of my

Thanks John, I'll look at your VFO project to see how you use the cores on the esp32. I already had the eSPI library but didn't attempt to use it with the ST7796S shield. I'm wondering if the 4-wire
