| Two-tone Transmit IMD Test Procedure | N7WS | on 21/10/17 |
| The ARRL Lab Test Procedures Manual indicates the the subject measurements are made at one frequency in each band at the manufacturer's maximum rated output power. My experience with two transceivers from the same manufacturer with several iterations of low-power and high-power modules has shown wild variations in IMD with respect to frequency and/or power level. Since the published product reviews show only one number for each order I wonder how this number is selected from the test data. Wes N7WS |

| 2200 and 630 Meter operating permission | N7WS | on 21/10/17 |
| The FCC Public notice regarding operation on the subject bands states that an application should be made to the UTC website: http://utc.org/plc-database-amateur-notification-process/. It goes on to say that UTC will respond via email and request that the amateur acknowledge receipt. In typical bureaucratic fashion they go on to say that if the ham doesn't get a response within 30 days, he is free to begin operating. Unfortunately, at least in my case, after filling out and submitting the form I have absolutely no proof that I did so and I have received no email from UTC. I have emailed and telephoned and left messages with UTC and received no response. Should I plan on operating or not? |
