If not then you can download the HT-37 manual at the following link: http://bama.edebris.com/manuals/hallicra/ht37/ Once the manual is downloaded, go to the page "3" and study the SO8 11 pin connector. Pins 2 and 3 are the relay terminals inside the HT-37 that control an external user provided antenna change over relay. You have to provide the external antenna change over relay and power source for the relay. All pins 2 and 3 are there for are to act as a "switch" turning the external antenna change over relay ON/OFF. The HT-37 does not provide 120VAC for the antenna change over relay, you provide that power source (see page 3 of the manual). You can find the 11 pin plugs that fit the HT-37's rear 11 pin socket on eBay or from Radiodaze.com. 73s Mike W5RKL |
