A few months ago I successfully built the low band QMX, and it was fully working. This week I had a short interruption of the power supply, resulting in a blown D108. I replaced it, and also updated to FW 1_00_016 (was 1_00_010 before). Connected a dummy load, did a couple of tests, and everything seemd ok. Then I connected the antenna, receive is good, but as soon as I TX, the SWR protection kicks in. I checked the SWR of the antenna with my IC7300, and it shows 1:1. Re-checked with analyzer, it also shows perfect SWR, so I'm pretty sure the antenna is good.
I disabled the SWR protection, sent a quick CW and was immediately spotted in RBN, so TX works.
If I TX into the dummy load, no/perfect SWR is indicated and TX works, but into the real antenna, it shows high SWR and shuts off.
Any ideas, what could be wrong?
Tnx Robert
