[QUOTE="izefisherman, post: 374301, member: 233523"] Yes, it was neglible here too when there is a little marigin on the signal. How many SNR % can you throw away on that TP before it breaks up Likvid? You also probably have a very short run of coax from your balcony dish which means there is ample IF signal strength left even with that loss/mismatch. However, many large enthusiast DX-systems involve long cable runs because it ain't nice to have a 150+ cm dish on the balcony (you should know from your past days with large dishes you refer to in every second posting) so the IF-level will be much lower when it reaches the tuner. I did measure the actual IF-side loss with a proper lab-grade spectrum analyzer, you didn't measure anything specific at all. The loss is OVER 6dB, plus you introduce huge SWR in your system, that depending on insertion point can worsen things further. Last but not least, I'm not the only one experiencing the mentioned problems with this RF-PCB and the fix corrected it in at least three cases. Read the vetrun thread again and check the dxtv.de forum on this subject. That RF PCB belongs in a 1 euro throw-away china toy. End of story. If you can't say it, I'll say it. Ize [/QUOTE]
