All Daiwa SWR meters can be selected to display average or peak power. The PEP value is found by different charge/discharge constants and therefore is not very precise.
In contrast to that the new CN-901HP has a true, active peak envelope power (PEP) reading which is important for PSK31 and other digital modes. This function requires an external 12V DC power supply.
The CN-802HP-3 has a max. range of 3000 Watts (compared to 2000 W of the CN-802HP).
