| Please help with 2m/70cm antenna mounted on tree | N1CAK | on 5/7/21 |
| What kind of antenna will you be mounting in the tree? The lightning surge arrestor should be mounted just outside where the coax enters the building. The ground rod needs to be connected to the house main electrical ground rod. Bill |

| New Ham Feed Line Question | WMKreider | on 13/3/21 |
| I would suggest two runs of coax if for no other reason than to keep it simple. Adding splitters, filters and switches adds additional losses to the already increased losses from an attic antenna installation. Bill |

| Newbie General Repeater Question | GrandAdam12 | on 22/2/21 |
| Tom, Not sure you understood Zak's answer. Everyone must be in range of the repeater (both transmitting and receiving) to hear each other. If you are talking on your local repeater you will not be heard on the repeater 30 miles away unless the repeaters are linked together. In other words the down link frequency of one repeater is not the up link frequency of another. Repeaters are linked by other means described above (wire line, internet, RF, etc.).

| FT3DR micro SD | KO4LKZ | on 29/1/21 |
| I have seen that problem several times. The radio can't read the card. The solution was a new SD card. You might try that. Bill |

| Amplitude Modulation | GrandAdam12 | on 25/1/21 |
| Think of each sideband as a signal. So when modulating with a single tone there are three signals, the lower, the carrier, and the upper. If using voice there will be many lower and upper (and carrier) sidebands each corresponding with the frequencies of your voice. Bill |
