With the most recent firmware, now a must own shack item! Any reason why a four band limit? Not enough io lines, memory ect. Bi or rgb led for error codes or band selection? Never got to build the v1

Update!!!! Listening to what Alan had said about L12, I just heated up the solder joints and tried it again. 40M is now GREAT! 80 is working too (but the receive level seems a bit low. 30 and 20

Demand must be in the thousands, and it soubds like you can at great expense source parts in the hundreds. We’re all rooting for you! 73, Willie N1JBJ

Hold on, I hit send too soon! I tried a different power bank and the trigger board kept a constant 12v even on transmit. I think the issue is not the board, but rather the battery bank. Regardless,

What battery bank are you using? The characteristics of that are gojng to be your limiting factor. I can’t tell for sure easily, but it looks like the KX3 can draw a couple of amps on transmit, so

Hi Folks, I wanted to follow up with you all. I tried the USB C trigger board on my KX3 and it failed. As stated previously by someone, when the current load it too high, it drops down to 9v power,

Honestly, I’m sick of China and try to avoid buying from China when I can. Today I received a package containing a SoloStove Smokeless Bonfire Kit. It cost well North of $200 on-sale and is touted

Some of us have too many irons in the fire already. Some of us don’t feel like brewing our own anymore. Some of us have been rolling our own for the past 45 years and now our time is worth more than

Hi All, Thanks for your patience with this. Please remember that I'm a CLUELESS BEGINNER, so it's no use thinking I'm capable of anything technical, LOL. Willie N1JBJ : I am on firmware V1.02 and have

Don't think I will ever use Ali Express again. Bought two items off same seller, only one arrived. Contacted him and he asked for a 99 pence payment to send the missing part of the order. Smelling a

I think the group he is working with have used several methods and combined them to try and get a result. WSPR was only one of the methods used. Be good if they could locate it and then it may be

I am surprised at the number of people wanting an automatic ATU. Most of us are using QRP or relatively modest RF power output. What is wrong with making a suitable ATU, there is nothing magic about

Hi QDX at the moment only supports 80, 40, 30 and 20m bands. It is fixed in the firmware and cannot be changed by the operator. In the future when we have managed to ramp up production to meet demand

Hello George I doubt mechanical expansion stress is a significant enough factor to be a concern. I don't see how adding a heatsink to the transistor could ever be a bad thing. Metal has to be a better

While waiting for the QDX availability I'm wondering if anyone tried or thought about running it on the 2200 meter and 630 meter bands ?

Hello Alan Really I think it is all, at best, wishful thinking. One could be a lot more harsh than that too. I wish it was true too. But I don't see how. If anyone can see a way, please explain to me

Are their any credible news outlets these days ? They seem more concerned about celebrity news or promoting certain agendas more in keeping with click baity Yahoo news level garbage. As a professional

I add thermal paste between the transistors and both the PCB and the washer. Figured that it cannot hurt in any way. [email protected]> wrote:

Check the current flow of both rigs. Heat shows up within each bs170 and it relies on convection. The new QCX heat sink expands the radiating surface it would be ideal except for the plastic package

I agree, utter nonsense.? The author selected data that might support his wish, ignored all other data, and ignored natural variations in signal strength reports due to myriad other factors.? I'm
