Document seems legit, so blatant scam and impersonation is probably not the case (not unheard of). However that amount is ridiculous even for FedEx, it is probably a mistake with a missing comma or

Hi, Gianpi, Could you run the resistance checks again, only with no power applied? There was something strange happening there, but it could have been the way the meter reacts to mixed signals. I

T1 heating... If heating you means warm such as 10F or 5C increase that's normal. If warm means more than 120F, that suggest something is not right IF Hot (greater than 140F/60C, something is very

I Just finished to build the ver3 today, After a wrong antenna connection the 4 MOSFET are gone...replaced and start TX again. But is hot...even for ft8 not only t1 also the transistor on the bottom

Response to an earlier post. But under this subject heading. I’m a long time and old amateur. I learned CW to get my ticket. Switched to SSB when it was the new best thing and then came back to CW

Cirsti, Our build session is not planned until the middle of July.? I will report back then. 73 Evan AC9TU

I replied privately before I realized hans-peter posted here as well.? It echos what Willie said.? As follows: Joshua

Check the manual for terminal-mode setup commands, pretty sure there's a gain control for audio out. 73, Willie N1JBJ

Hello Hans, Group, I also confirm the issue. Just listen to the transmission and seems it come from SI5351a itself. This noise is not present when transmitting from the console program so I guess is

I'm new to this, but I've been playing around with WSPR 2.0 and running my TS-430s at 1 to 2 watts. Seems like I can be heard over most of the world. My question is, how low can the power supply

Hi Evan, Thanks again for your feedback.Agree with using less voltage to supply R2 R4. I think 5V is even better. Let us know your experience with the new rev3 QDX regarding the T1 and R2 R4 issues.

Hi, Evan, Yes, I have the operation manual. The first thing I did after the smoke test was to cycle through the apps to do audio and RF sweeps and a transmit test. I also verified in configuration

Good evening Jshua, Thank you for your answer, that helped me a bit. I adjusted the TX and RX gain on the bottom left of the screen. So now the TX signal works, I can also see the Rx signal in the

Hi Cristi I built my rev 1 QDX for 12volts.? I had multiple failures of the output MOSFETs and IC5.? Some were software issues (the version of the software shipped on the Rev 1 was known to have a

I agree with Curt. Unless you have it in an environment where it is subject to constant vibration, I can't imagine your needing to secure the inductors and transformers. Perhaps if you travel a lot

Hello again Jim. Just did a video to show you how appear. Let me know if need more measure. By the way, Initially I said the volume will not changes the volume, but increasing yes, you can crustal

Hi, I am getting about 3 hz drift on 20m wspr. Thirty meters seem fine. I wonder if anyone has had similar experience. I have used the tcxo in a U3S and never had a problem up to 6m. Any ideas? G8LDJ

Gary Offer the dude privately via button enough to more than enough to cover shipping. Curt

Well, it looks like Q3 is bad and maybe Q4, Q5, and Q6. The diodes appear to be ok. I will take a crack at replacing these surface mount devices with my unsteady hand and poor eyesight...wish me luck!
