You could connect your peripheral USB devices (mouse, kb, GPS, SDR etc) to a separate powered USB hub, I've found that works fine in practice.

Hallo baltika_no_9,
thank you very much for the advice. The problem with the power supply is solved. Now an active USB hub powers the "power hungry" USB devices keyboard with mouse, touchscreen, VHF receiver and gps mouse. This works.
My Raspberry Pi 4 boots without problems even with the USB hub turned on. Therefore, I suspect that the active USB hub is not backpowering (better said, there is no backpowering preventing my Raspberry Pi 4 from booting).
I bought this USB hub via Amazon for about 21 Euro: atolla USB 3.0 Hub, 15W (5V/3A), power supply included, 4 ports with separate switches, one additional charging port.
Kind regards, Rüdiger
That's good to hear. Confirming that the hub you have works on the pi might help others.
