TK 981 deviation

[mass-man]

Bought half a dozen TK 981's and ALL have very low audio. Must be deviation as settings in the software are in the 40's and 60's!

Until I can get to a service monitor, any baseline settings for deviation, low, medium, high?

thanks....

The normal deviation for the 900Mhz commercial band is a max of 2.5Khz
and typically is about 2.1 or 2.3Khz.

The 900Mhz commercial band has always been narrow band right from the start
so that would be normal.

That would be why you think the audio is low on these radios but it is actually normal
for them.

You don't want to exceed the dev settings. The trick is to increase the mic gain settings. That way you don't have to swallow the mike to be heard. This was tried here on some 900 ham repeaters. The dev gets boosted, but it's too much for the receiver in the repeater to swallow, & the audio comes out rough through the repeater. But leaving the dev setting alone, & boosting the mic gain sounds fine & gives the required results. I don't know if the Kenwood radios have both settings adjustable, but the Motorola MTS, & MCS do, & it made a big difference. GARY N4KVE
