HOWTO: Install an UI-7 AM/FM unit in an Icom 725 HF ham transceiver

iAfter installation, I was able to listen to my own broadcast over the internet via a Kiwi SDR radio somebody else in my city hosts so I could verify that it was transmitting in AM and FM modes correctly. Financially, I'm not sure paying $100 (+50 S/H & tariffs ) is really worth it to upgrade a $300 (used) radio for AM/FM modes when I don't (yet) have a strong reason to use those modes on the HF bands....but I like the buttons on the front of my radio to actually work. [Although I'll probably NOT buy/install a narrow band CW filter until I learn code...]
