Depends totally on the power from the adapter. ? ?Trigger cables ask for a specific voltage and the adapter delivers it to the best of its abilities. Which in the case of cheapo Chinese supplies is

The ripple will depend on your power bank, not the cable.? The cable simply applies the proper 'trigger' resistance to usb-c protocol pins to cause the PD power bank to switch to the desired

If you are using GPS for frequency stabilization, this may be a software bug that Hans has in the queue ( after ssb) to work on.

Hello, Does anyone have any experience with ripple from the USB C PD power cables? I just picked up a USB C PD power cable that provides 9VDC @ 3A (mine measures 9.3VDC with a multimeter). The QRP

Great work, Ed!

Tony, Hans would be looking for low cost in an SMPS on a $100 kit, and those IC's all seem to be designed for a max of 1 or 2 Amps. The TPS561243/TPS561246 costs $0.10 quantity 100 direct from TI,

Hi, Qrp Labs has changed the 0.6mm wire to 0.33mm in recent kits. Test of Hans showed no change or even better performance with 0.33mm as of tighter windings likely. This is described in many places

*Selling QMX+ Rev1* Includes GPS module, development board, and power lead. Fully functional—made my first QSO with it! It's a fantastic rig that will be

I'm delighted to receive my kit (Order ID: 94083) but noticed that it seems to have the wrong gauge of wire. ?The larger bundle of wire is 0.33mm diam, which is correct. ?The other, smaller bundle,

Chuck, Regardless of software definition or not, the hardware will have variations, and your ears will have variations, and band conditions will vary. Your AGC will respond to those variables

I have a freshly minted QMX+ and I am experiencing the same problem.? CW seems to work fine.? FT8 was working last evening but then suddenly stopped. Now when I hit tune or try to transmit, it

Since the AGC settings seem to be very dependent on the ambient noise on the band, it would be helpful for me to know on which band the settings are optimal, and what level the ambient noise is when

Steve - I was actually rereading the posts last week, and I adjusted my settings to be somewhat the same as yours. Here's what I compiled from a couple of threads - I apologize for not accrediting a

I thought the whole point of using SDR's was to eliminate most of the difference between examples of a given radio. W1AW works perfectly with just about any AGC setting here at my location... mostly

The radio is a Ver. 1 QMX plus that in general performs exactly like I expect.? It does not have the GPS option installed, and there is no battery in the clock battery slot.? The radio is used for

Hi Stan, Hi All, here a success message. After yesterdays experiment running QMX direct from 3.3V and getting confirmed CPU and rest of 3.3V Rail OK, I spend all evening/night rechecking QMX over
