I'm sure you will be okay with T37 at 10 watts, also, it's the temperature rise due to losses that limits power capability of these cores I believe, based on this

Does anyone know if the QLG2 can be put on Back Order rather than be replaced by the QLG2-SE ? I have tried to email Hans through the QRP Labs web site but it keeps getting rejected. 73 Hew VA7HU

Well thanks guys for the info, I must admit I tried this several times and keep getting the tx sending a message. However, I did have the QLG2 connected and beacon mode set in the menu. I was backing

Just a long shot, have you adjusted for contrast?

Hi Guys, thanks for your comments, Hans does say in section 4.4 of the 10W HF Linear PA manual; 5) Always use a Low Pass Filter between the Amplifier output and your antenna system. and also says as

Hi, I've given another look at my faulty QCX (see https://groups.io/g/QRPLabs/message/42064 ), which all of a sudden stopped booting up. I've had success hooking it up to a PC via an AVR programmer:

No issues at all Evan. 🙏

Same experience. I thought my QLG2 was gone forever based on their tracking. Then is miraculously appeared on their planned date.

a bit off topic. If unattended transmitters are not permitted, what about the balloons circling the world ?

Sama is correct that the QRP-Labs low pass filter kits have capacitors that are rated for up to 5watt input to the filter. The option would be to find equivalent parts with higher voltage rating for

Hi Mont It's not a bug, it works correctly, it's more an "inevitability"; the button is loaded with several different functions depending on whether tapped once, twice, or one long press. On the left
