ASHATA UHF Modulator, TM70 UHF TV Link Modulator AV to RF Converter IR Extender with Channel Display, Supporting PAL/NTSC with USB Charge Cable for PC Laptop PS3 TV STB VHS VCR Camera DVD

This was a straight replacement for another similar model that had worked for over 20 years and used to shoot my cctv footage to all TV's in the house. I did have to change the input Coax plug for an F Type and dispense with the existing 12 volt power supply then use the included 5 volt USB power lead which went straight into a spare USB socket on my DVR unit but all was good. On powering up it defaulted on the correct channel 21 plus the PAL option but there was much audio noise. Reading the instructions I saw that the audio signal frequency could be altered by holding the Channel + button for 3 seconds and I found an alternate frequency that suited, so all was fixed. I am sure that many units will have been returned as "Faulty" when all they needed was attention to the instructions provided.

The unit was easy to install and easy to change or pick a channel the sound output was just electronic mush and needed adjusting instructions not very clear. Contacted the vendor but it was a waste of time they just gave the run around !

Good product need to ensure you also prchase the correct connectors

No sound / Hold chan sel button down for 2-3 sec then set to 6 meg/sc (for uk)

I bought this 12 months ago and have only just got round to using it. Using F-type to co-ax connectors it wouldn't pass my TV signal through, even though I'd made sure it was on PAL and not NTSC.And the video and audio (using channel 21 of the CVBS signal I was putting through it) had lots of interference too, even though I'd selected the correct frequency beforehand.It's going in the bin unless the seller wants it back for a refund and investigation.

Unfortunately didn’t work
