The Sinking City 2 has a plethora of puzzles you can solve, and the Wireless Room Radio Frequency Puzzle is one of them. You have to match the frequency of the radio according to the clues (or testimonies, as they are called in-game) to complete it. There will be three frequencies that you have to enter to complete this Radio Frequency Puzzle in the Wireless Room. This puzzle is easier than the Church Obelisk puzzle, since all the clues are in one room for your convenience.
Radio Frequency Puzzle Clues and Explanation in the Wireless Room of The Sinking City 2

The Wireless Room is found by going left from the lower door of the Medical Records room. Once you have done so, you will come face to face with a Radio Station, along with three different brains that provide you with ‘testimonies’ or clues.
These testimonies go as follows:
Testimony of ‘Cornelius Wright’: The secondary frequency is higher than the primary. The primary? Well above 20 Hz. And whatever you do, don’t believe a word Pence says.
Testimony of ‘Ambrose Pence’: The primary frequency is between 10 and 20 Hz, and some say it brings bad luck – especially on Fridays.
The tertiary? It’s exactly double the sum of the first two. Oh, and Dunwich… he is half-correct.
Testimony of ‘Silus Dunwich’: Round the primary frequency to the nearest ten, cut it in half, and you have got the secondary.
The tertiary must be under 30 Hz. As for Wright – he’s always wrong.
*From the testimonies above, I have bolded the parts that are important for deciphering the three frequencies, while underlining the parts that are lies/incorrect. Yes, that means Cornelius’ entire testimony is false.
Radio Frequency Puzzle Solution in the Wireless Room of The Sinking City 2

You have to enter three frequencies to complete the puzzle. These are primary, secondary, and tertiary. The solution and explanations for the same are listed below:
- Primary Frequency: 13
- Explanation: Pence says that the primary frequency is between 10 and 20 and is an unlucky number. 13 is a well-known unlucky number. Moreover, it specifically references Friday, alluding to Friday the 13th.
- Secondary Frequency: 05
- Explanation: Dunwich says that you have to round the primary frequency to the nearest ten and cut it in half. Rounding 13 to the nearest ten gets us to 10, and further cutting it in half leaves us with 05 as the answer.
- Tertiary Frequency: 36
- Explanation: Pence says that the tertiary frequency is double the sum of the first two frequencies. 13 and 5 add up to 18. Double of 18 is 36, which is the answer.
Entering 13, 05, 36 in sequence will clear the puzzle and reward you with Dream Essence.
