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

Brien: Thanks so much for this. I suspected this was the case. I actually jumpered the diode at the relay in the amp to put in transmit mode, and the QMX+ worked perfectly fine. I need to upgrade the

If you are using COR function with the amp this will happen as the QMX sees a high SWR while the relays are switching over.? ?If you can use PTT input into the amp and set a TX delay of about 15mS

Hi All, I'm very new to building kits, and radios in general. Working though my 60-15m QMX and I am at step 2.12 where I am winding and attaching L511, L506, L512, L508, L513, and L510 and I wanted

Thank you Hans! Yes, I tried to use DiGi by mistake )) Now I tried USB and there is strange thing: it works, but TX power is very low. Peak to Peak voltage is just 3 Volts. When I work in other

I recently built the WA3TFS linear amplifier featured in the March QST. The build went very well and with my old MFJ 20M QRP CW radio, 3W in gives 20W out with a peak 4A draw. So, I tried to interface

Good info! I just ordered two.

Hi les, That is the same mic, (I have 4 of them), I use on all of my Bitxs and my QMX+. I always get good audio reports. I know they are not the most attractive looking mics around but they do

Jack, As far as current draw for these small single board computers like the various models of Raspberry Pi, the published values are probably maximum values. These might only occur as transients or
