Default Tk-8180:K out of frequency programing

Hi Quick question,

I Have programmed in 3 channels that are in the 433 mhz range and the radio works ok on these channels but beeps for about 20 mins why on these channels before it stops beeping.

why looking in the Programming software under advanced settings it has tuning point Low 450.05 and low2 467.55

is changing the low point here to 433.0 going to mess up the tuning of the radio and will it stop the annoying beeping.

Those are Error beeps because the PLL is unlocking because it is out of band. Also you are using a mobile radio in a low power radio band.
1.You can make the PA draw high current and burn up and die.
2.You could be interfering with Burglar Alarms, Life Safety Pendants, TV Remotes, Wireless Door openers, ECT.
LPD433 (low power device 433 MHz) is a UHF band in which licence free communication devices are allowed to operate. The frequencies correspond with the ITU region 1 ISM band of 433.050 MHz to 434.790 MHz, and operation is mainly limited to CEPT countries. The frequencies used are within the 70-centimeter band, which is traditionally reserved for higher power amateur radio operations in most nations worldwide.

LPD hand-held radios are authorized for license-free voice communications use in most of Europe using analog frequency modulation (FM) as part of short range device regulations,[1] with 25 kHz channel spacing, for a total of 69 channels. In some countries, LPD devices may only be used with the integral and non-removable antenna with a maximum legal power output of 10 mW.

Voice communication in LPD band was introduced to reduce the burden on the eight PMR446 channels over shorter ranges (less than 1 km) .[citation needed] In some EU countries voice is not allowed over LPD.

I have a Ham licence and the only 3 channels being programmed are 3 ham repeaters, so will not be interfering with anything the unit is not pulling any more current than the normal channels and the rf output power is also the same, also not located in the us or eu. I was just trying to avoid also installing a ham radio in the vehicle.

the radio is not capable of operating below about 438MHz, you have a high split model.

you need a TK-8180K2 400-470, the 400-470 version if you need to go that low.
