I didn't follow the link but You might try a torrid on the orange line and/or between the raduino and nextion.

My concern is whether we are measuring a power ratio or a voltage ratio - I am suspicious we could be measuring the latter -- see https://en.wikipedia.org/wiki/Decibel#Voltage I am thinking that if

Well, the AD2 is really a (software defined digital) scope with FFT ... so the front end is a scope front end, the probes are high impedance voltage input.? Therefore the display is relative to

I bought one for my bitx40 they work out very nice. I take the element out and put it in a mini mic. http://www.jlielectronics.com/microphones/com-mic-jli-52b/ -- David ?N8DAH Kit-Projects.com (

I'm on v3, also. I tried looking for the original post, but couldn't find it. Anyway, your descriptions sounds about right. I thought it was odd back when I tried it for the first time...I have a few

Even if one is rich, i suppose that there is no point in investing in mics that zerve high end systems for ham use. We dont really need more than 0.3 to 3Khz at the maximum Regards Sarma vu3zmv

If you can't afford a Behemoth microphone (hi hi) you may try high sensitivity (around - 24db) electrec elements you may find at large vendors (Mouser etc). I opted for dynamic elements (not for

My two cents... First I've tried with a karaoke mic and a audio console? Good: I get 10W of power without effort, talking quietly Bad: The signal transmitted is extremely low pitch (very dificult to

Yes the uBitx might have some flaws but not hard to find issues with other radios or how a ham is using it, mods, running power, etc. There are a lot of aging radios out there, my 840 is of the latest

Attached couple of mods I've been using ...One variable audio filter and one mod Re 386 ... The 386 shows what I measured on the ic with a 10 uF cap pin 1-8 ...flat from near dc to daylight ..What I

:) I think the TX of the ubitx has been the most tested, loved and blamed by hams in history. Also because it should be assumed that commercial ones should have no basic issue in terms of harmonics

Looks like the ubitx screenshot didn’t get attached properly, here they both are again for comparison. Sent from Mail for Windows 10 Sent: Wednesday, April 10, 2019 1:51 AM To:

Hi, I just did a quick comparison test between my ubitx and Yaesu ft-840 radio. I used a SDR on a laptop with a up converter, the SV1AFN with a 200mhz LO. I had a multiband antenna on it from a

Looking to use my BITX on SSB and cw and trying to figure out a good mike for it, either hand or desk. Will likely take to Costa Rica later in the year and possibly leave there. Suggestions or where

Which bitx are you using. I have uBitx and R52 is near audio predriver and its a 2n3904. How do I do this on a uBitx v3. I guess this is what we call a carrier burst? Joe KD2NFC

Ron thanks I found them.? see if your instrument under units can be changed from dB v to dB m.? I think that may change the result.? Curt
