Orion MK2 bugs
Posted: Mon Mar 26, 2018 3:29 am
Hello,
I used an Orion MK2 board for some time.
A nice evolution of apache labs.
I found two bugs on my board and a 7000DLE at the moment.
First: 384000Khz sampling rate with activated PD results in unclean spectrum and audio
Second:
RF power meter without Alex shows a maximum of 760mW, while at the output of U4 (FWD Power OPA) is about 3V to measure, so the OPA is overdriven. To solve the problem, I have replaced my Orion MK2 R16 (original 1k as Hermes) against a 2.2k resistor, which gives roughly a division factor of 4, now are 2W RF out according to the display around 500mW
best regards René
