Upgraded screen - better contrast and adjustable backlight for improved sunlight readability. 

The award-winning SP-400 is simply the most powerful portable radio you can buy—like having a complete standby radio stack in your flight bag. The all-in-one radio makes a reliable backup for emergency use, but it’s also perfect for listening to ATIS, getting clearances before engine start or just monitoring local traffic.

But a great radio is worthless if it’s hard to use. That’s why our staff of pilots, flight instructors and aircraft owners spent so much time making the SP-400 intuitive and easy to use. It has all the features you need, but none that you don’t. There are no confusing menus, no memory bands and no complicated squelch buttons—just turn it on and type in a frequency. After all, an emergency is no time to look for an instruction manual. Includes alkaline battery pack, antenna, wrist strap and instruction manual. Measures 5 1/2”h x 2 1/4”w x 1 5/8”d.  Five year warranty.

Why the SP-400 is the pilot-friendly radio:

  • Oversized, high-resolution screen—twice as large as most other radios
  • Enhanced screen backlight with adjustable contrast for better sunlight readability
  • Large, soft keypad is easy to use, even in turbulence
  • No menus or memory banks—just type in the frequency
  • One-handed operation for fast emergency access
  • Unmatched battery life, powered by easy-to-find AAs
  • Quick-change battery pack—switch in just 3 seconds!
  • Backlit screen and keypad
  • Dedicated squelch and volume knobs for precise adjustment


Sp-400 NAV
  • Last frequency flip flop makes it easy to switch back and forth 
  • Visual memory recall shows five memory channels per screen 


  • Full ILS display—the only portable radio with this feature! 
  • VOR with large CDI display and automatic bearing-to-station readout 


SP-400 Weather
  • NOAA weather radio receiver built in
  • Nationwide coverage with pre-programmed stations


  • Dedicated 121.5 button for instant emergency communications
  • Sidetone—hear yourself talk when using a headset

  • "Sporty's SP-400 Shines. Its performance is clearly exceptional."
  • "You can easily pick this unit up and use all of its features without touching the manual."

Since our very first product was an aviation radio, I’m partial to our SP-400 Hand-held NAV/COM. It’s an amazingly powerful radio, and one I never could have dreamed of in 1961.

can it be hooked up to the airplanes antenna?
A shopper on Aug 11, 2016
BEST ANSWER: Not unless the antenna is disconnected from the existing radios; and then, you (more likely, your radio shop) would need to ensure proper impedence matching. A cheaper and simpler solution is the optional Remote Antenna Mount, which allows the antenna to be positioned in a side window or other favorable location for improved reception.
Is the 5 year warranty transferable? SP-400
A shopper on Sep 1, 2016
Does a new certified remote pilot need a license to use the SP-400 handheld transceiver? Beginning last Monday, some remote pilots would appreciate the use of a transceiver for the same short correct comms with ATC when inside or under controlled airspace just to advise ATC of their ID and location before and after takeoff, which is required in the authorization (usually) given days before. The alternative is to use the mobile phone, but that adds to the tower workload. This is being discussed in formums now.
A shopper on Sep 4, 2016
BEST ANSWER: Per current FCC rules, an FAA-licensed airplane automatically receives a radiotelephone station license, and a licensed pilot receives a radiotelephone operator's license to operate the radios in the plane. Neither a UAS (as the station) nor a remote pilot (as the operator) would appear to benefit from these dispensations. If you Google "airplane radio license" you'll find this info at the FCC website.
Can you hook up a handheld mic/speaker to the sp400?
GliderPilot on Jul 24, 2016
BEST ANSWER: Although I don't have that setup, I would think if your plugs and jacks are standard that it would probably work. I purchased the adapters from Sporty's which plug into the SP400 and then allow you to plug in your headset. You now transmit using the PTT button on the SP400 and headset mic. The side tone generated allows you to hear your transmissions. Received communications are through the headset of course.
8.33 compatible ?
Cédric C on Dec 12, 2016
BEST ANSWER: It receives 8.33 kHz but will only transmit on 25 kHz.
Some of the comments indicate that the 400 eats a lot of batteries. Two points: Can it be plugged in a lighter plug to operate it and/or to recharge rechargables AA's or the Ni-Mah battery pack while in use? Thanks
Charles B on Sep 6, 2016
BEST ANSWER: Yes it can be plugged into the lighter for use and charging. However, for use as a backup, fully charged batteries will last long enough to get you down safely. That said, I plan on buying the Ni-Mah battery and desktop charger. For me, it adds just a little more peace of mind.
I just tuned it to Cincinnati Approach from home, but can't hear anything; is this normal?
A shopper on Oct 13, 2016
BEST ANSWER: Yes this is normal most of the time unless you are at or very close to the airport. My SP 400 is the same and only picks up traffic close to me, but picks up fine and works quite well once airborne. If you get the SP400 in the air and see no change you should call sportys for an exchange.
How far is the range on this unit...Please?!
A shopper on Sep 3, 2016
BEST ANSWER: According to the product manual, the transmit power is 5 watts at 85% modulation. For comparison, the transmit power of the common Bendix-King KX125 panel nav-com is 5 watts minimum, 7 watts nominal. Thus, range is potentially similar to that of a panel nav-com. The limiting factor is primarily the antenna and the shielding of the airframe, and the latter is specific to your airplane -- my results don't count.
What does it come with?
David S on Apr 30, 2017
BEST ANSWER: It comes with transceiver unit, strap, and antenna. There is separate order if you like all connectors or rechargeable Li ion battery pack.
my son is a pilot wants two way hand held radio in case his radio in airplane fails. is this what he needs?
A shopper on Dec 3, 2016
BEST ANSWER: Yes, this is a good choice. With the Sporty's Headset adapter (P/N 8635A - $26) he can plug directly into his headset
I'm considering this SP-400 and find the battery comments discouraging. Could it be the peak current drain during transmitting damaging the fragile Alkaline battery chemistry? Has anyone used Lithium primary (non-rechargeable) cells in this radio? If it kills batteries while NOT in-use, it would be a worthless device.
A shopper on Oct 5, 2016
BEST ANSWER: I bought this handheld and put in high dollar camera batteries ( I never trust rechargeables) I pull it out and listen to the atis every prior to every flight and now and then give it a transmit radio check with ground cont.
Works like it should... I read folks whining that they left it fallow for a long time and it was dead when they needed it.... If you are relying on a piece of hardware (that runs on batteries) best to check it....
"dig you well before your thirsty"
Is there a compatible earpiece/lapel mic that will work with this radio?
Dan T on Oct 14, 2017
BEST ANSWER: Yes, you can atttach your headset to it with the adapter.
What is the size of the screen?
David B on Oct 3, 2017
BEST ANSWER: The screen measures 1 11/16th inches x 1 11/16th inches.
Does it have a scan feature to listen to multiple frequencies?
Ed A on Aug 28, 2017
BEST ANSWER: Yes it has a memory scan feature.
Does my headset plug in?
A shopper on May 22, 2017
BEST ANSWER: If you would like to use this with your headset you will need the adapter, item 8635A.
Hey can it pick up like csx?
A shopper on Apr 5, 2017
BEST ANSWER: This radio will only receive aviation communications and navigation frequencies.
How many watts output ?
A shopper on Mar 27, 2017
BEST ANSWER: 5 watts.
Does this unit have the DME built into it?
john s on Mar 9, 2017
BEST ANSWER: It does not have a DME built in to the unit.
I am a aspiring flight student who also owns a boat. Would the s a good marine radio as well?
dangerami on Mar 8, 2017
BEST ANSWER: This would not. It does not transmit or receive on marine frequencies.
I'm a UAV Pilot, and while all my flying and video/photography work is in accordance with our transport ministry, I'd like to have coms if we are operating in or near private strips or helipads. (Eg. We were doing roof inspections near a hospital that turned out to be the region trauma centre for air evacuations) would this radio be suitable for contacting ATC or aircraft to inform them of our operational ceiling and location? The pilot/controllers are ground based often in urban areas although occasionally we assist with search and rescue work.
Elliott R on Dec 30, 2016
BEST ANSWER: ctr ( control zone) or ATZ (aerodrome traffic zone) is classified as air space from A-D. In any of this air spaces Must have Bilateral & Continuos radio comunications. The airspace of a CTR (includes a strip inside) usually is 5NM circle lateral limits, and from ground/2000"vertical. i have an apartement 1Nm from TWR LPPR and my experience says: comunications ground-ground are poor (i never had ctc with Twr from home GND-AIR is ok in ctr limits for low altitude!
Conclusion: for traffic information shpuld always report begining and end of activity in the frequency
May I use the sp400 in Europe/ Netherlands/Germany?
thijshe on Nov 25, 2016
BEST ANSWER: Why not? Whats matter , is that ' if you have a rádio qualification for air-air or air-atc' transmitions!
What is the comm output transmit power?
David C on Nov 21, 2016
BEST ANSWER: 5 watts.
Is there a way to make it transmit on 8.33 spacing, even if at a cost to modify? That is what questions about using in Europe etc mean. Europe and the UK are changing to 8.33 spacing and this radio will soon have no use there unless it can be adapted to transmit on 8.33. Thanks ps Very annoying for us, but we have no choice.
