The affordable TERA TR-505 is a 16 channel commercial-grade multi-use dual-band analog FM FCC Certified GMRS and MURS (and Ham) handheld radio which is ideal for emergency communications, business or security operations, or a variety of recreational activities including camping, hiking, hunting or special events.

The TR-505 provides reliable emergency radio communications for peppers, friends, families, Neighborhood Watch & CERT groups, and businesses to keep in touch when other methods of communication break down.

This radio is NOT A TOY like the blister-pack FRS/GMRS radios you get at the superstore that claim ridiculous operating ranges – These are sturdy, full power, commercial two-way radios designed in the U.S., with high performance, great (loud) audio output and an IP54 Dust & Water (splash) Resistant rating. With our signature ReadySafeGo™ service, we charge the battery pack, custom program for you (see options above), and test each unit (including antenna), so your new radio is guaranteed to be usable the second you open the box, and to NOT be DOA!

The TR-505 operating range is as good or better than any other affordable GMRS or MURS radio, even with its stock flexible antenna, which is better than most radios in this price range. The claims made on cheap blister-pack radios, even by major manufacturers, are mostly bogus and certainly misleading (that asterisk is there for a reason). A 5 Watt radio with a 2″ antenna will not operate up to 35 miles (often not even 6) except almost as a fluke in the most accommodating of settings.
Realistically, handheld radios are going to give you from 1/2 mile to 2 or so miles, give or take. In the city, this will be on the lower end, and in rural settings with only a few minor obstructions, you can see a communication range of 5-7 miles, possibly more. We won’t make any bogus claims that you’re going to get 30+ miles with a 2-5 Watt radio, but we think you’ll be pleasantly surprised by how well this pocket radio actually performs. As well, with our hi-gain whip antenna upgrade or an external mobile-mount or roof/tree-mount antenna (for base station use), you will see a significantly improved talk range, even when communicating with another stock handheld.
Note: The latest version of this radio may say “Recreation” instead of “GMRS/MURS” (as pictured here) on the front lower base of the radio, but the electronics are the same.
GMRS or MURS Recreation, Business & More!
Factory Pre-programmed with 16 GMRS (General Mobile Radio Service) UHF channels, including both repeater and direct handheld to handheld communications (MURS VHF radio options available also). Ideal for use with most outdoor activities including: hiking, biking, skiing, and hunting. Also usable for business, security and personal safety operations! Full 4 Watts of transmit power on UHF (5 Watts on VHF – 2 Watts default in the MURS configuration) for increased range and coverage area. Note: We offer several custom programming configurations for this radio – see the Radio Programming Options above and Radio Programming Charts below!
Voice Announce & Feature Keys
Built-in voice announce feature for memory channel, battery level, channel lock/unlock and scan on/off status. 2 programmable side-keys provide access to other optional features, such as VOX mode, squelch monitor, power level, and alarm. Note: For FCC compliance, the hi/low power side button has been disabled (user-programmable with optional USB cable, or with our custom programming service – see the Radio Programming Options above).
Rugged Design & 1 Year Warranty!
Rugged handheld radio designed in the U.S.A., with loud receive audio. Includes a 1 year limited warranty, factory supported and serviced in the USA (Southern California).
Simple Operation, VOX & Li-ion Battery
Easy to operate radio with its compact size and simple to use top mounted volume and channel knobs. Optional hands-free VOX (Voice-Operated) mode with use of a VOX-capable headset or earpiece. Each radio includes a Li-ion rechargeable battery (which provides up to 30 hours of operation between charges with battery-saver mode), 2 hour desk charger, flexible antenna, belt clip & user manual.

NoteGMRS (General Mobile Radio Service) operation does require a license (currently $70 for 10 years – typically takes only a couple days to obtain online from the FCC). MURS (Multi-Use Radio Service) is license-free for 2-Watt operations. MURS uses the VHF band, which generally offers better outdoor/rural communications than GMRS, which is better for indoor/urban environments. Having the capability of both bands (and NOAA “All Hazards” National Weather Service stations) in the same emergency radio is essential!

IMPORTANT: The custom programming options for this radio are meant for emergency communications during emergency or “SHTF” (S#it Hits The Fan) situations. You are solely responsible for operating this device in compliance with FCC licensing and regulations, regardless of how it comes programmed. We are not responsible for any harm caused by the use or misuse of this device. Let us know if you have any questions before purchasing.

Reviews(6)

  1. Rated 5 out of 5

    Easy To Use and Strong: Custom programming for dual band GMRS and MURS works well.
    Radio is solid, proven by kids dropping it down the stairs, and it came out without a scratch and still working fine.

  2. Rated 5 out of 5

    Good Radio For The Money: Reliable and clear. As stated in the auction do not expect 10 to 30 mile range. Very strong signal at 1/2 to 1 mile in hill country. Your terrain will affect your range.

  3. Rated 5 out of 5

    Excellent Radio: This transceiver is very clear whether transmitting or receiving. The range is short, about 3/4 of a mile, which is not bad considering I live in a part of the country that has quite a few hills and valleys. [BSR Note: Customer may have been operating on UHF (GMRS) instead of VHF (MURS), which would likely result in better range in his area. We have average reports of 1-5+ miles on these radios. As with all two-way radios, your range will depend on obstructions and operating conditions.]

  4. Rated 5 out of 5

    Great for Legal GMRS/MURS/HAM Use: If you want a legal GMRS/MURS/HAM radio, you can’t do better than this one, at least at this time.

    This radio is FCC certified for use on both GMRS (but not FRS-only channels) and MURS, so you can operate unlicensed on MURS, which is much less crowded than the FRS/GMRS channels. MURS also operates on VHF frequencies which tend to penetrate outdoors better than UHF (GMRS).

    Personally, I use a combination of MURS (Ch 1-5), GMRS (Ch 6-10), Ham (11-15) and NOAA WX (16) similar to the custom programming available from this vendor.

    The IP54 rating makes it an ideal hiking radio where friends and family can use the MURS channels without a license. To talk to others using the more common GMRS, just switch channels. Finally, if you are a ham operator, you can program in local repeaters to give you wider coverage. I include a couple of 4W/5W 440/2M simplex channels as well.

    A very versatile radio for the money and it seems to be well built, have a good receiver, and be easy to operate for non-technical people.

  5. Rated 5 out of 5

    Overall Great Radios: I programmed these radios for MURS, with monitoring on selected NOAA and Marine channels. I plan to use them mainly for hiking and four-wheeling. I have been looking for programmable, handheld MURS-certified radios with removable antennas for a couple of years, so I was very glad to finally find these. The GMRS capabilities were a very pleasant bonus.

    The programming software was easier to use than I expected, but the software help file and the user manual are poorly translated into English. However, with a little tinkering, I was able to figure everything out. The programming charts from bettersaferadio.com were extremely helpful in choosing the programming that works best for me. The great part about the software is that you can save the programming files and just upload whatever profile you want to the radio without going through all the details every single time.

    Using MURS, I got ~2 miles of range with moderate line-of-sight barriers in a suburban area using the stock antenna on high power, which is more range than I expected.

    Using the ANTMAG at home and a MURS45 antenna from Firestik on my Jeep, I was able to get ~4.5 miles on low power, again with moderate line-of-sight barriers, including some significant hills. Not ideal terrain for radio, but it is a real-world scenario. This is ~1.5 mile more range than I get on the CB radio in my Jeep using a similar length antenna over the exact same terrain. I think the VHF/MURS signal gets through power-line obstructions much better than HF/CB signals. I have power lines in front of my house and I can’t use CB there, but the MURS radio worked great.

    The speaker on the radio is quite loud; most of the time I keep the volume turned down as low as possible.

    When I plug headphones directly into the radio, I can hear a clicking sound when the Rx power save feature is enabled. I think this is due to the Rx circuit cycling on and off to save power because the interval between the clicks is a function of the power save ratio selected. The clicking is only heard through headphones directly attached to the radio, and not through the radio speaker, the speaker-mic, or headphones plugged into the speaker-mic. I plan to simply disable Rx power saving whenever I plan to use headphones without the speaker-mic.

    Overall great radios. I can’t recommend them highly enough.

  6. Rated 5 out of 5

    KUDOS TO BSR!: I recently purchased and received SHTF Programmed Radios [TR-590-SHTF & TR-505-D], quickly and perfectly packed and programmed. I was greatly pleased with the Manuals and quality of the Radios. Superb and gives Motorola a “Run-for-its-money,” commercial grade (I’ve used them before). Also purchased the extended ‘whip’ antennas and they were of high quality. Mark at BSR spent a lot of time counseling me prior to the sale…a courteous personal touch. I always will do my business with BSR in the future……great service and good products.
