Hi Tim, is the Fnirsi scope-multimeter the one that costs about $90?? I've been interested in that one.? I have not seen the tablet. The Fnirsi RLC tweezers are great!? I was using them recently to

Hi Jack- I've never done that yet.? However, PCBWay provides that service, and they should be able to quote it. The boards I have received from PCBWay are excellent quality.? Just a guess, their

Greg: What would be your best guess if, say, the RF board were populated with all SMD parts, including IC's, but not the "standup" parts like voltage regulators, electrolytics, IDC/SMA connectors?

From PCBWay, my orders of five prototype 100x100mm boards has been about $28 for quite a while. The last order, after the May tariffs kicked in, was $55.? There is tariff, tax, and tariff processing

According to the shipping charges on their website, DHL is running $22.82. In addition, "Global Standard Direct Line" is back. But not $1.50, rather $12.69. I think this reflects tariff costs plus the

I have a full range of Siglent equipment however for recent Electronics merit badge I used one of these: ** FNIRSI? 2C53P 3-IN-1 50MHz 250MS/s Dual Channel Tablet Touchable Oscilloscope

Thanks, John! Jack, W8TEE

About $33 I think. Not at the PC now. -- John P. WA2FZW

I've got the same issue with a completed radio. It does not affect the spectrum display or the S meter, only the audio. It's confined to 17 and 15 metres. The pumping occurs about twice per second. It

What was the charge for shipping by DHL (ballpark)? Jack, W8TEE

I was glad my hip held out and I could come by. Wish I could have spent more time chatting. Tim

Just ordered some PCBs from JLCPCB. Looks like price for 5 boards is back to $2, but there was a $3.63 charge for customs and duties added. DHL shipping cost seems to have also increased by about 50%.

And Hamvention is OVER! We had a great time… in-doors this year. Sold 50 fill T41 board sets, ten 20W PAs, ten of the latest T41 books (signed/personalized editions), and many other kits. Suitcase

Hi John, I use a two-channel Siglent SDG 2122x generator that can synchronize the channels and phase shift one by 90 deg - hence quadrature signals. The Spectrum analyze is not entirely necessary and

Hey everyone! Tim, W4YN donated some very nice 3 wire pre-made cables, twisted, to be used to connect the teensy audio hat to the main board (the 90 degree pins). I will include these free of

Correct. That was due to an update. Oliver has unlocked the method of locating the old files for you… the “Old files” directory in each of the BOM, schematic, gerber, etc directories. Dr.

I've not tried testing this particular configuration, so I'm speculating here. If you don't have any receive circuitry populated then the only signal present to be digitized is the self-induced noise

The yellow LED next to the reset button on the Teensy board lights up brightly and dimly. And the audio is pumping most strongly on bands 17 and 15 at the same time. What's the problem? Only the
