MSP430G2232: RF Interference of capacitive touch from Ham Radio Operator

We have a product called the Hear Back OCTO which is a professional headphone mixer used in recording studios all over the world. We have been building this for about 5 years now and have only had this happen a couple times with customers but we currently have one we are trying to work with that reports issues with the capacitive touch buttons that we have setup with a MSP430G2232IPW20. But after swapping out units several times, the problem only occurred when it is in their geological location. Being a Ham radio operator myself, I wondered if there were any nearby operators so I looked up their address on a Ham Radio database and their was one two doors down and the operator is a General class which means they can transmit up to 1500 watts (through a 20dBi antenna, this could potentially be over 90kW of effective radiated power). We are having the customer talk to this Ham Radio operator to see what frequencies they are transmitting on. I am only a technician class Ham so I could only test with a 2 meter (145Mhz) radio but I was able to get the capacitive touch to trigger when I got my antenna within a few inches and putting out about 7 watts of power. I experimented with placing some ferrite beads on the capacitive touch inputs to the chip and also some caps around 10pF to ground to see if I could filter the RF. It did significantly help so this may be the solution, but I wanted to reach out and see if you had any previous experience with this.
