If there is a single unit of measurement beyond volts and amps that can be considered nearly ubiquitous in ham radio, it would have to be our friend, the dee-bee or dB. Key to computing values in dB is the logarithm, so this quiz also combines the two — are you ready? If dBs aren’t your cup of tea, the ARRL website contains a tutorial on decibels that may he…

This works most areas where text can be edited on the radio (eg APRS, memory labels and prepared messages) Seems to be many different methods depending on where you are in the menus: text entry: left wheel, Up/Down buttons, DTMF keypad cursor position: left wheel (push), right wheel rotate, arrows, or A/B buttons

The DB18E has been constructed and installed on the tower at 45 feet. The SWR on all bands is AOK. Now for a demonstration of on-the-air performance.
The average daily sunspot numbers this past week dropped nearly 73 points to 56.4, while the average daily solar flux declined nearly 47 points to 110.7. The average geomagnetic indices were up about 50 percent, but it was still very quiet. The difference was mostly due to events on January 17 when the planetary A index was 13 — higher than in recent weeks, but still moderate. The cause of the…

Does receiving a cell phone call interfere with Intoxilyzer 5000 breath tests? Must a cell phone be transmitting to cause radio frequency interference to an evidentiary breath test instrument? Some experts opine that police radios and cell phones are only a problem if there is a TRANSMISSION from the breath room. This video suggests otherwise. This instrument is in need of maintenance. More research is required to determine if approved instruments are reliable when cell phones are permitted in the breath room. Range Exceeded means that the instrument was reading apparent BrAC beyond its capabilities. Invalid Sample means the instrument thought it was seeing mouth alcohol effect caused by recent consumption of alcohol. Almost any error message can erroneously be caused by RFI.
