Hi @kannans!
I had also trouble with my TA-1.
Important note. The TA-1 has center and shield connected inside the antenna!
I described my procedure here:
Try to use the rtl-power tool adding one brick after another, as Cees suggested.
At first I would try a different power supply on the raspberry pi. I have one culprit here with that one connected to the RPI there‘s so much noise that I do not see a single signal.
I would go and test my station in VHF Airband first. See, if you have a local Tower that transmits weather reports 24/7.
Good Luck!
