| Satellite using an HT | KB8VHI | 3 days, 23 hours ago |
| https://www.work-sat.com/my_gear.html "It is preferable to work the FM sats in full-duplex mode (where you can hear the downlink as you key your mic). But only one recently manufactured HT did that well in V/U and U/V modes: the Kenwood TH-D72a (discontinued 4Q 2020)" In practice most dual band radios desense too much on receive so it is often more practical to use two radios if you are on a budget.

| What Determines How Many Watts an Antenna Can Take? | jgaz | 1 week, 2 days ago |
| There are now infrared cameras sold to consumers. Some are phone attachments. These can be used to verify the expected temperature rise of antenna components. Even better would be to use a professional grade camera used by fire departments. Perhaps they would be willing to come out with their gear to make sure there are no issues in your attic.

| https://www.ecmweb.com/national-electrical-code/code-basics/article/20891084/article-810-radio-and-television-equipment NEC says to ground the mast and feedline. They do not specify grouding a matching transformer. In some cases a CMC may help but it is usually not necessary. There is no straightforward method of optimizing a CMC on an "all band" antenna. No, NEC does not require that the power supply and transceiver bonding be run out to separate ground to the lightning arrestor ground. Zak W1VT ARRL Senior Lab Engineer |
