Hi All, The tariffs on my last two shipments were applied by DHL. Previously dozens of shipments to Mexico had no duty. DHL asked for a proof of citizenship and added a brokerage fee. The total came

Good morning Alan (I guess good day for you), I haven’t made any modifications to the equipment as yet. I’ve got to find/order a 5v regulator and then put it in the circuit. The series capacitor

I've added my headset adaptor to the Wiki page, /g/QRPLabs/wiki/39099/219907 I did it for my Heil headset but it also seems OK for PC headsets with separate headphone and microphone

The wiki page QMX External Microphone Options ( /g/QRPLabs/wiki/39099/219954 ) has been updated by Chris <chris.rowland@...>. *Reason:* Add Headset-Mic with Heil or

Dan, a high probability for a broken controller. Do you have a sharp tip for your DMM to probe voltage at a pin of the controller? Driving 300 mA you may check voltage drop from Vdd connection to the

The terminal Hardware Tests- Diagnostics can test transmit and show the Power and SWR.? If these read values for Power and SWR then T507 is fine.

thanks again, Ludwig CPU barely warmed at 200mA, and at 300mA I got a voltage drop to 2.5v and the CPU did warm slightly. I couldn't detect any other components warming. Is it game over? Dan

I received the cable and voltage monitor yesterday. Both appear to be good quality for the price paid. I should have the power bank by the end of next week. Noticed though that the 25k one doesn't

de minimis treatment "shall not be available" for China, quote from a Feb 25th US article from npr. It would not be a surprise if that were to be extended to other countries. Andy -- The universe is

Tom, Hopefully that has not damaged the Progrock. But I'm fairly sure the output of the Progrock has a positive voltage on it. I suggest you try with a series capacitor, maybe 10n. Then no damage is

Moin Raijko, Did you also experiment with a headset ? I would rather like to use a headset and As I understand the ones for Computers are too weak. By the way the Radtel one is not available actually

Hello all DX Commander stated in the last video that tarrifs will not apply to his antennas as it is below certain price limit. We will see if it is true and if it will also apply to

Hi Jeff, First of all, thank you for your reply — I really appreciate you taking the time to help! In my previous post, I was experimenting with different input voltages using a bench power supply

Hans, I set the QMX to "practice" mode whenever I want to disable the transmitter and use the QMX as a receiver only in CW, DIGI or SSB mode. This makes sense when I listen with a random non-resonant

Thank you Paul and thank you George. 73! de Bekir TA2RX 5 Nis 2025 Cmt 05:12 tarihinde George Korper via groups.io <georgekorper= [email protected]> ?unu yazd?:

Hi Bekir, With the supplied parts, and the circuits as designed, as the frequency increases the output will diminish. So far I haven't seen a post that shows otherwise. 73, George

The setup I used is in the image below: Power supply is from 3, 3400mAh 18650 Rechargeable Batteries in the Power Bank Box. ( https://www.aliexpress.com/item/1005006076485612.html ) Microphone was

I rather doubt that's true... If I understand, the differences in output between every unit have more to do with variations in the parts (the output transformer, toroids and associated caps of the
