I think it is wrong to say Çafrad is the heart of TF-2000 anymore. Design changed considerably and that tweet line is outdated. ÇFR is now tasked with surface detection, EW and IFF, not anti air warfare, which is the main task of the TF-2000.
"Since the S-Band UMR, which was designed for early warning purposes in the old design and designed to detect and track only air-breathing targets at long ranges, will take on a significant part of the load in the new configuration (in addition to early warning, it will also perform the function of precisely guiding HİSAR and SİPER G/Ms to the target), the ÇAFRAD configuration now includes an X-Band Radar (ÇFR) that will focus only on surface engagement. In terms of survivability requirements, the single mast concept has also been abandoned in the ÇAFRAD System, and the single-sided fixed antennas of the S-Band UMR are placed on the right, left and aft sides of the ship's superstructure (bridge), while the antennas of the EFR are located on the integrated main mast."

I feel like that is an old photo.
It is, it's from when it was tested aboard a Gabya Class frigate back in 2018.

Cooling capacity only 4.5kw feels low. It is similar to APG-83's (estimated) air cooling on F16 B70. Wouldn't that put limitations on MURAD's duty cycle? @TheInsider @Anmdt

First of all Murat is GaN based radar,APG 83 is GaAs so Murad radar is more tolerable to heat from APG83 this make more power for transmission of RF for the same cooling capability.I thing on the reciever side signal to noise ratio is also better than GaAs system,this is more important than the power of RF signal transmission.Contrary to public belief about APG 83 is also use liquid cooling system,but with help of air cooling system of F16.Air cooling limit of F 16 is 9 kVa and there are many systems need cooling.APG 83 is limited in terms of TR power by software to protect radar.We do not know anything about this on Murat nose radar.
