New HAM with fading issue

[WSEL330]

Thank you Gang. I am aware that RG58 is not a good choice. That was what was on hand at the time to play here in the shack. I have and am using RG213 and KMR400 for testing and radio play.

Update: I contacted Radioddity about the TYT TH-9800. explained my issue. I have had this gear for over a month but they replied that they would replace it. I am not surprised due to the reputation of this particular machine BUT they did act fast with no pushback, as least for now. Thank you again for all of your input to lead me to not keeping a piece of gear that doesn't work. As a newby, I would have kept it and eventually trashed the $ amount paid.

If you are trying to save money and don't mind a dual band radio and you like how the TYT TH-9800 is setup, then look at the TYT TH-7800. The TH-7800 is a better radio compared to the TH-9800. 

I have a couple of TH-7800 radios that I have been running for about two years now and haven't had any issues with either one.

I am glad you do not have issues. Unfortunately, some one on here was correct. You get good and bad ones. The unit was replaced but took a long time transiting the ocean. The replacement's speaker intermittently worked when it wanted to. The programing cable suspiciously did not have the TYT logo as the previous one AND it would not write to my radio. This was the last straw. The organization I purchased it through did provide free return shipping and refund my money. So I'll reread this thread and get one of the previously recommended.
