sommerkamp/yaesu ft-707 cw issue.

[p.larner]

i have this radio,its a rebadged yaesu ft-707,if i select cw wide or narrow on any band the speaker emits a loud (1khz about.) tone,its loud and the vol control wont change its volume,i can still hear stations in the background but the background hiss can be heard and the vol pot will change that,but the 1kc tone is always comming over the speaker no matter where i set the vol,cw does actualy tx ok tho if i monitor on a web sdr,any ideas where to start?,i have the yaesu ft-707 sm,cant find one for the sommerkamp model tho,will post in the radio section too,thanks+73
