I solder all of my power pole connectors, easy to do and IMO a superior connection, last thing I want in the field is a shaky connection. John KK4ITX Visit: www.zaarc.org. ?

It was not in fact live as it turns out, but rather a well put together 2 hour video of what he estimated was 6 hours of footage over 2 days, with two back to back errors on the screen installation

Ok, so some progress - After reflowing a handful of cold solder joints, some of which were some of the early connections on the initial capacitors, the auto power on problem is now resolved. I did

I kept looking for a SSB menu and the realized this refers to the new beta firmware. Aha ! I am still on _027 firmware. I’ll get on this tomorrow ! Thanks. 73, Jamie WB4YDL

I have tried many sets of BS170, TN0110 and now one set of the FDT86256. The TN0110 works the best for me on all bands. I have never blown up a set of TN0110 and I get the best power out across the

COR will always result in the transmitter's output being hot-switched with a resulting very high VSWR; transient, but it only takes an instant to blow a FET.? If PTT is available it is always

For all of the single-winding toroids, it does not matter which direction you install them. Use the hole closest to the wire; if you wind them as described in the manual, the starting end will be on

I keep a supply of 100pF and 1000pF NP0 leaded capacitors handy.? It only takes a second to tack-solder a couple onto a board or slip them into terminal block connections to help with RF bypassing

I also just made this post with some Winlink VARA-HF setup details: /g/QRPLabs/message/143063 Stan KC7XE

Petrov, I use the following VARA HF settings in Winlink: For when the picture gets deleted: Radio Model - Kenwood Amateur, USB mode (not USB Digital), Use Internal Soundcard Select appropriate COM

My QMX+ (Rev.3, 12V, FW 003) complains about low voltage at the finals. See picture: 9.7-9.8V in red. I checked the voltages at C506 and C529 and they show the expected divider ratio of ~5.7:1. But

Both the QMX and QMM+ share the same software.? "PTT to TX delay "is in the SSB menu.? It appears to be applied in CW mode also.? If you are using CW you might want to turn on Semi QSK and put a

The manual is very specific and there are plenty of pictures. Each toroid has a set number of turns. Follow the instructions. Prepare the ends by scrapping and heating the end when you install them.

Hi Volkert, Sorry to hear that you're still having issues with the driver. I use a Linux operating system and try to avoid using windows as much as possible. I'm sorry, I don't have a windows 7

Popular American West Coast Youtuber is building a QMX on stream tonight at 8 PM EDT (US East Coast Time). Seems like it might be of interest to the

If my memory is correct, yes. Make sure you have scraped/sanded and tinned all the magnet wire before installation. Use sufficient heat, with a large tip. .rr

A mistake on my query - this refers to the QMX NOT the QMX+. Question then: can the transmit delay be adjusted ?? 73, Jamie WB4YDL

Hi va3rr, Thanks for your response. So it looks like in your picture the top left toroid of the 6 inductors I can see the final tun goes through the center through hole. Is this the case for all of

It is very strange. As I said when I used Vara sound card settings where QMX was mentioned as output/input device TX power was very low. Than I decided to choose mic and dynamics as input and output

Each turn thru the toroid hole counts as a turn. The toroids must be wound in the direction shown in the manual. Here's some pics of my mid-band QMX. GL de
