You want about 2W drive. There is no way possible to get 40VPP on the gates.? To do so you wired the input transformer as a step up... aka severely didn't do what was proscribed. Correct is less than

You can try this, and it works for me with a Rock 4 SE. I have supplied ideas for using RPI and Asus Tinker board too, but Rock4 SE definitely works. Since it’s simply performing a read of the fq

Although at that spacing there might be some issues with power handling and flashover. Probably best to taper to 200 ohms or so and use a 4:1 balun from there.

hi folks I would like to update my QCX CW Board 2020 Rev5, the one with aluminum case to firmware 1.09. Currently version 1.03 is installed. Can someone provide me with the 1.09 update file? I can't

Good morning sir! How much are you asking?

Thanks for the reply, Yes the power output seems very weird to me as well, I'll go back and check the low pass filters construction heck maybe somehow I either put the wrong toroids in or caps etc

It is quite doable to perform any impedance transformation you need by way of slow tapering of the ladder line; generally the closer together the conductors the lower the characteristic impedance

Hi Ken If you try to enter the menu system on the front panel, when the menu is already accessed by a terminal, doesn't it already show you an error message informing you? And why would WSJT-X be

PETG is not uv resistant, just more temperature resistant and more brittle than PLA. For uv resistant only ASA

I have 500 of those vine ties here, very good for OWF. I imported them from Holland a couple of years ago. If you would like some give me a pM. 73 Mike G8NXD

Hello Anders I read your paper carefully but I am sorry, I don't feel that I understand enough to comment in detail. Are there any examples of this implementation for SSB generation? What are the

Equally, when in remote control via the USB port, I wondered for ages why I could not access the menu from the front button until I realised it was still under control from a shutdown WSJT-x

Even though CAT keying via the KY; command works fine, I still think it would make sense when you are in CW mode, if the CAT commands to switch to TX mode also activate the key. So I added this to my

An idea found on Internet: 6mm irrigation tubing cut to appropriate length and a small ty-rap fed through to pull the 2 lines tight. Easy to make and cost is minimal!

Hi Mark Thanks, good suggestion. I will add something on the LPF screen. 73 Hans G0UPL http://qrp-labs.com https://www.buymeacoffee.com/g0upl [email protected]> wrote:

Hi Tristan, Congratulations on your new license and on completing your first radio kit. Is this a QMX, or QMX+?? I will assume QMX, since that is what your message said, but they are significantly

WSJT-x does not handle the 'mode' switch commands properly in some cases for QMX, so you should set WSJT-x to 'none' for mode control.? This tells WSJT-x to not send any mode commands.? You must

We have reports of quite a few rigs that work fine, then fail during calibration or digital transmissions. Once those FET's are installed on the board, the gates are fairly well protected by the ESD
