Question about Midland Radio Communications
Hi, Eddie here writing from Germany..... when talking to work mates from my truck they say that I am very quiet to them over a distance of about 2 miles. Also I can be driving behind a work mate having a conversation without any problems but when we go our different ways I lose contact after about 3 miles....if that.
I have a brand new Sirtel Santiago 600 antenna (apparently very good) approx 1.5m on the cab and a second hand Midland 48 Plus 80 channel CB
Some one mentioned modulation....does anyone know how to adjust the modulation on one of these?
Would it make a difference if I changed the set to a 40 chanel version?
Shall I sell the cb and buy a brand new one :-) ?
Thanks in advance, Eddie.
Since your concern is both on receive and transmit, the common denominator would be the antenna system. The antenna should have a metal mounting to serve as the ground plane. Said mounting/ground plane must be electrically grounded to the rest of the truck. The next area to check would be the PL-259 connector. It should be soldered/connected right with no shorting. Next would be the cable which should be low loss RG-58. Last to check would be the SWR of the antenna. Most mobile antennas could be fine tuned to a specific frequency/channel by adjusting its length. There would possibly be 1 or 2 Allen screws for this purpose. In some cases, it may be necessary to trim off a few mm of the rod.
On your concern re modulation, am afraid that your radio has built-in limiter so as to prevent over modulation and comply with European restrictions. Additionally, the Midland 48 Plus has been programmed to transmit only 1 watt in AM (4 in FM) when the display shows D or D2. Additionally, you might want to consider a power microphone.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
