Frequently Asked Questions - HD 3 Combo MEGASAT

How do I connect the HD 3 Combo to a satellite dish?

Connect a coaxial cable from the LNB to the LNB In port on the meter. For terrestrial or cable, use the ANT In port. Power on the device and navigate to the appropriate menu (DVB-S/S2, DVB-T/T2, or DVB-C).

How do I align a satellite dish using the meter?

Go to DVB-S/S2 > Calculate Angles. Select your satellite and location. The meter will display the required elevation (tilt) and azimuth (horizontal) angles. Use the Alignment mode or Compass mode with the built-in motion sensor to adjust the dish until the signal locks.

What does the 'LOCK' indicator mean?

The LOCK indicator shows that the meter has found and locked onto a valid signal. It displays green when locked and red when not locked. In satellite mode, it appears after selecting a correct satellite and transponder.

How do I perform a spectrum analysis?

In any measurement mode (DVB-S, DVB-T, DVB-C), select Spectrum from the submenu. Press F3 to change the power level range. Use the arrow keys to navigate the frequency band. The spectrum graph shows signal levels across the frequency range.

Can I update the firmware?

Yes, firmware updates are possible via the Mini USB port. Download the latest firmware from the Megasat website, copy it to a USB flash drive (via a USB-to-mini adapter), and follow the update procedure in the System Settings menu (if available) or as described in the manual.

How do I set up DiSEqC or Unicable?

In DVB-S/S2 > LNB Settings, use the arrow keys to navigate to DiSEqC/Unicable. Press ◀▶ to select the desired DiSEqC port (1-4) or Unicable mode 1/2. For Unicable, press OK, then select the user band and frequency as per your LNB configuration.

Why is the signal strength low on terrestrial channels?

Check the antenna power setting in DVB-T/T2 > Settings. If using an active antenna without its own power supply, set ANT Power to 5V or 12V. For passive antennas, set it to Off. Also ensure the antenna is correctly positioned and the frequency is within range.

How do I reset the device to factory settings?

Go to System Settings, scroll to Factory Reset, and press OK. Confirm the reset when prompted. This will delete all user-entered data, including edited satellite lists and custom settings.

What is the battery life and how do I charge it?

The built-in Li-Ion battery provides up to 3 hours of use. Charge via the included 230V adapter connected to the DC port, or use the 12V car charger. The Power indicator lights red during charging and blue when full.

Can I use this meter for DVB-C cable TV measurements?

Yes, select DVB-C from the home menu. It supports frequency range 44-870 MHz and QAM 16/32/64/128/256. You can view signal lock, power, SNR, BER, and perform spectrum analysis and tilt (level comparison across channels).

How to measure

The measuring instrument is equipped with a motion sensor. As soon as you turn or tilt the meter, the values are displayed in real time.

1. Place or hold the meter horizontally.
2. Use the green arrow (2), which shows you the current direction in which the meter is pointing.
3. Rotate the meter towards the satellite (1) until the green indicator points to the satellite. Now you have the rough direction in which the dish must point.
4. Now tilt the meter until the angle of inclination has reached the specified number of degrees (the angle of inclination varies according to geographical location). Now you have to adjust the rough inclination as the dish.

4. DVB-S / S2 (Satellite search)

4.6.2 Compass-Mode

1. Displays the current tilt angle. Tilt the meter by the value of the predetermined angle adjust.

2. Rotate the meter to adjust the horizontal angle.

Example:

You are in Berlin and want to set the satellite „Astra 19,2° East“. The values you need to adjust the dish are:

• 29.2^ tilt angle (vertical)
  • 19.2° east of south (horizontal)

Imagine the meter to the south. Turn it to the east direction (to the left). Pay attention to the degree (2) displayed by the meter. The angle must be 19.2^ .

Now tilt the measuring instrument until the angle of inclination (1) is at 29.2°. The position as you hold the meter now must be transferred to the mirror.
