Just replace it and see. I have had failures of emitter resistors. Raj

Thanks Allison. The explanation on Farhan BITX40 mention like this : ..."There is an extra stage of amplification (Q14) to boost the very low level 14MHz SSB signal from output of the microphone tip

The test file I used that worked is the Touch_shield_kbv.ino file and it has this:- // the regular Adafruit "TouchScreen.h" library only works on AVRs // different mcufriend shields have Touchscreen

Touchscreen test

R82 cooked likely because Q90 died. Possible cause: Excessive RF, say using another TX near by. EMF/EMI Aka lightning or static buildup on antenna. Other parts around that transistor were not

Expectations will be in the range of +13DBM or about 20mW. IT could be higher but likely not lower. Hard to call the actual loss of the triple tuned BPF

Hi Joe, How do I select that in the Arduino code? The pics and test example footage are attached for your kind perusal. As you can see touchscreen works otherwise. Pat VU2OGA

What driver did you select in the arduino code? You need to ensure one of the define is selected. The one you choose would match your display boards driver number. Which mcufriend test examples

I didn't see any touch screen pins on the back of the display, so I don't think it's constructed for touch screen use. Jack, W8TEE

Yes Joe is correct, it plugs in to both the uno and 2560 Mega. Displays fine on both too. Example tests run fine on both. It's just the touchscreen that doesn't work. Display is fine. Won't work on

Hello, does anybody could give some information, how much is power output from the exciter of BITX (especially this BITX Spectra), not exact value, estimation is ok. I just want to make sure my

Gordon, These are searches outside of the Groups.io site, not the message searches provided in the Groups.io search engine. I would have thought that would give better results pertinent to the

Hola, estoy trabajando en la sustitución del Arduino Nano del uBitx v6 por un módulo con ESP32. Las principales ventajas que tiene este micro

Hi Evan, There is never any call for flames in of forum, even the political forums. I know, I know, that doesn't seem to stop some. The causes are probably not simple and even if they are the

Here’s a search where I didn’t presume knowledge of the fix:

I did a simple Google search, and came up with a whole slew of hits, several of which I wrote myself

Same here. Just have my supply at 13.8 and never changed it on my v3 --

Chris, I operated that radio on 13.8 volts for a year and it didn't blow up, I'm sure it will be alright. Joel N6ALT

Have you tried using the "search sites" ability of Google? For example, "mail.yahoo.com: bitx" (no quotes) will return all hits on Yahoo mail that match bitx. Sent from Yahoo Mail. Get the app

All, I have done multiple searches on Groups.io. From that empirical data I have surmised that the text of the post is not being searched, only the title and hashtags. That is not really helpful
