Frequently asked questions

The integrated SWR meter in the Uniden PC78LTX is designed to allow you to monitor your antenna system to ensure maximum power output and performance. If the SWR is too high, it could potentially damage your radio. So, it's an essential tool in maintaining the overall functionality and longevity of your CB radio system.

The Instant Channel 9 feature allows you to instantly tune into Channel 9, which is typically used for emergency communications. The convenience of this feature allows truckers, and other users quick and easy access to this emergency channel when needed.

The PA function stands for Public Address. This means that the Uniden PC78LTX can be used as a public address system when connected to an external speaker. This can be particularly useful in various situations, such as making announcements or calling for assistance on the road.

The Hi Cut function on the Uniden PC78LTX is an audio filtering feature that helps to reduce high frequency noise and interference. This feature significantly improves the sound quality of the received signals, making communication smoother and clearer.

    • Inexpensive and Powerful
Style: PC78LTX
This radio was clear and powerful out of the box. With an Astatic 636l,and 102" bumper mounted whip mounted on an '06 Sterling Triaxle dump. I had it peaked and tuned @ "Bob's CB Shop" for $25 after the first year, and now get out easily to 4 miles. For around $200 for the whole setup, I highly recommend this product and seller. (Update 2023) After 4 seasons of blacktopping and aggregate hauling this radio still works flawlessly! It outperforms it's direct competitors (Cobra 29 ltd) and often times higher end radios. It's now mounted in a 2022 International HX620 triaxle using the factory antenna mounted coax with a 4' or a 2' Firestik II antenna with quick change attachment, since some silo's are lower also in town limbs and other obstacles. Also using an Astatic 636L that I bought at the same time (the original mic sounds tinny!). Replaced the led that backlit the meter a year after purchase when it got peaked and tuned. Highly recommended! ... show more

Good basic out of the box CB. My " BIG" radio bit the dust and i needed something fast for doing oversize loads and getting traffic updates. This fits the bill. Range with my particular coax cable and single antenna is a Mike to 1.5 miles. Simple and basic , fits the bill for now.

    • Seems to be a good radio
Style: PC78LTX
Just got this radio to mount in my truck. It's large but has all of the features you need. I was able to wire it up in about an hour (already had antenna and COAX cable ran, just had to switch out radios and power wires). I managed to lose the little screws that holds the radio into the mount. I was able to use a M5 .8x12mm machine bolt from Ace Hardware. Couple month later update: radio is holding up well. Friends are able to hear me clearly at pretty good distances even with obstacles. I'm still very happy with my purchase. ... show more
