I posted this in the wrong topic so I've moved it here. Just got in a 2.4 and a 3.2 Nextion display.? I'd seen some comments on the current draw and the possible need for a heat sink on the existing

The $60 Chinese microscope is actually kind of nice. It's a whole lot better than the $15 Chinese USB microscope I've been trying to work with -- about 10X as stable, easier to focus, an actual stage

I have updated the AGC/Click mini-kit "ordered/shipped" list in the "Files" section per today's information. There will be some delay before more kits can be shipped because I'm out of AGC boards and

my thoughts, as indicated in these posts? its very hard to come up with a 'universal' BUS. I think a BUS suited to the project in? hand like uBITX, or one with a similar 'block diagram' is a better

Mine has the WX brand TDA2822.? I put a 6v regulator in the 12v supply line to the chip as suggested on this group and it has been working fine for a couple of months now.? The audio is loud and

I've used these encoders for other things and yes they are fragile. I got so annoyed with the one on the Raduino I pulled and ancient mechanical mouse?out of junk, the kind with a DB9 serial

Tim has it right.? By time you get to RV1, the signals are what they are.? There is no adjustment prior to that other than audio level from the mic. Allison

Howard, The mixer where the spur is generated is the mixer formed by T2/T3 that is about? 28db (after allowing for filter losses and all)? later in the stream and if that mixer is overloaded you get

Thanks, Skip, I was thinking along those lines. Did you put the pot between CW-TONE and ground and feed the wiper onward or put one end of the pot & the wiper where R250 was? Mark? ? AA7TA

And ...? we have both Tom and Don active in the forum if you have questions. From the bottom of that webpage: "The SolderScope was created by Tom Williams, K9AC and Don Cantrell, ND6T." Don mentioned

I see I did not indicate where my encoder came from. It was Digi Key. So once again. *Order Details* Your salesorder number is 54975240. *Details* *Available Quantity* *Backorder Quantity* *UnitPrice*

Tom, Thank you for this. I just purchased a set of loupes and was disappointed that they really didnt help. I now have a use for them. Now to find a lamp stand... Thanks again, Marco - KG5PRT

I had the identical symptoms with my BitX after it was assembled. It was the encoder that was the issue. They are fragile so I ordered 5 and was very careful when I made the switch. It came to life

Re: #52380 "Seems to me you could DIY something better than those $60 Chinese special microscopes ... " Consider a SolderScope. (See QRP Quarterly, Apr. 2018.) (www.qrparci.org)? Its a DIY binocular

I had this problem when trying different software versions.? I had success by uploading it again to the Arduino.

And yes, rotating only causes the display to flicker the last two freq digit from zero to fifty. After pressing the encoder and getting the change band option, turning causes no change. Same with the

It only varies 50hz. It has never worked. It was suggested that I install the denouncing components to solve the problem. I have done so but no change.

Thank you! to everyone who pitched in to HELP. Chip

*Howard* (WB2VXW) called this morning and we went thru quite a bit of testing and things were not added up, until I mentioned that I had replaced the heatsink, made sure it was isolated from ground

Howard Many Thanks, This Group is an awesome resource.
