Haneda Airport

Terminal	Recommended Receiving Practices	Main Visual Range and Targets
Terminal 1 (Observation Deck) Recommended TWR Frequencies 118.1 MHz (Runway A/B TWR)	Set the center frequency to around 119.9 MHz. Monitor both 118.1 MHz (Runway A TWR) and 121.7 MHz (Terminal 1 GND) simultaneously to track the entire process from pushback to takeoff.	・Runway A (RWY 16R/34L) [Right in front] ・Runway B (RWY 04/22) [Far to the right] ・Ground operations for JAL, Skymark, StarFlyer, and others
Terminal 2 (Observation Deck) Recommended TWR Frequencies 118.65 MHz (C/D Runway System TWR)	Set the center frequency to around 120.0 MHz. Simultaneously monitor 118.65 MHz (Runway C TWR) and 121.6 MHz (Terminal 2 GND). Clearly track international flights and aircraft making consecutive landings on Runway C.	・Runway C (RWY 16L/34R) [Right in front] ・Runway D (RWY 05/23) [Offshore to the right] ・Ground operations for ANA, Air Do, Solaseed Air, and others

Step	Control Tower (Sample Frequencies)	Key Roles	Content and Characteristics of the Exchange
1. Preparation	CLR (Delivery) 121.8125 MHz, etc.	Flight Clearance	“Flight XX, flight plan from Haneda to Kansai International Airport is approved." *Confirmation of route, assigned altitude, transponder code, etc.
2. Travel	GND (Ground) , 121.7 MHz, 121.6 MHz, etc.	Ground Control	Permission to push back and taxi from the terminal to the designated runway. *The runway to be used is determined by “Taxing to Runway…”.
3. Takeoff	TWR (Tower) 118.1 MHz / 118.65 MHz, etc.	Airfield Control	Permission to enter the runway and take off. Begin taxiing upon receiving Cleared for takeoff.***
4. Rise	DEP (Radar Departure) , 120.8 MHz, 119.1 MHz, etc.	Exit Control	Guidance immediately after takeoff, while climbing to the upper air route. *Guidance until handoff to upper air route control.

Step	Control Tower (Sample Frequencies)	Key Roles	Content and Characteristics of the Exchange
1. Entry	APP (Radar Approach) 119.1 MHz / 119.4 MHz / 119.7 MHz, etc.	Access Control	Guidance for aircraft descending and approaching Haneda from the air. *Alignment with the landing runway and spacing adjustments.
2. Landing	TWR (Tower) 118.1 MHz / 118.65 MHz, etc.	Airfield Control	Landing upon receiving Cleared to land.*** Instructions to exit the runway after touchdown.
3. Ground Level	GND (Ground) , 121.7 MHz, 121.975 MHz, etc.	Ground Control	Permission to taxi from the runway to the parking position (spot) after landing. *Proceed to the spot via the designated taxiway.

Differentiating Tower Frequencies by Runway
At Haneda Airport, the control tower (TWR) frequencies are assigned based on which runway is in use.
- Runways A and B: Primarily 118.1 MHz (TWR)
- Runways C and D: Primarily 118.65 MHz (TWR)
The key is to switch the TWR frequency to match the runway you’re currently viewing from the observation deck.
Batch Monitoring Techniques with 9GRadio (RTL-SDR)
The primary frequency range for Haneda (118.1 MHz to 121.975 MHz) falls within a bandwidth of approximately 4 MHz.
By setting the center frequency of 9GRadio to around 120.0 MHz, the TWR, GND, and DEL waveforms will appear side by side on the waterfall display, allowing you to see at a glance where communications are taking place.
