DuraTrax 75MHz Radio Frequency Checker DTXP3110

This is the DuraTrax 75MHz (channels 61-90) Radio Frequency Checker.

Features

• DuraTrax 75MHz Radio Frequency Checker DTXP3110

• Automatically scans all thirty R/C frequencies in the 75MHz band and identifies those frequencies in use

• Each frequency is shown by a dedicated LED, LED showing channel in use stays lit and unit continues to scan 300' (91m) range without external antenna, 1000' (305m) with external antenna (not included-available separately, DTXP3111) see COMMENTS

• Pevents accidents due to unwanted Rf interference from other modelers' radio equipment

• Fits easily in pocket or car bag

• One year limited warranty

Comments

• For clearest reception and best performance do not sit frequency checker on ground. Also do not aim transmitter antenna directly at frequency checker, as transmitter's weakest signal emits directly from the tip of its antenna.

• This frequency checker indicates when another R/C transmitter is on a particular channel. It's important to note that the frequency checker is NOT well suited to show very brief, intermittent Rf signals that could cause interference which may be present in the environment near or between R/C channels.

• When using the external antenna, extra channels might appear to be in use if the checker is physically located very near a Tx which is emitting a signal. Moving the checker several feet away from the Tx should clear the problem. If used inside buildings which have a lot of steel/metal in the structure, extra channels might inadvertently be shown and NOT using the external antenna may deliver the best results in this situation.

• The instruction sheet incorrectly states that "Range is up to 300 meters w/o external antenna" and "Range is up to 1000 meters with external antenna". INSTEAD of "meters" it should say "feet" in both places.
