Jim I use the old Timewave DSP 59+ external unit for several reasons. My acoustic filter speaker isn't real efficient, and the K2 doesn't drive it to the volume I would like. So, the DSP unit provides extra amplification to drive the speaker. In addition, the DSP filtering supplements the K2 filtering. However, with the K2 crystal filters and the internal DSP option, I seldom need additional filtering. Another feature of the external unit that I use a lot is the AGC function. If you are using headphones, listening to a weak station and suddenly a strong local comes on calling him, you get a great blast of noise in the headphones, and it hurts. The AGC option clamps down on this and saves my ears, so I use it a lot too, especially in contests. Hope this helps, Jim. Good luck and 73 Bob N6WG

Is there a modification that can be made to increase the volume? My hearing is not great. The fact that the speaker is oriented up instead of forward doesn't help. When I put the DSP in I usually have to boost the AF Gain about a quarter turn. It's not unusualy to have it maxed out. The RF Gain is always max clockwise. Most headphones available are 8-32 ohms so switching to headphones only eliminates some outside noise and doesn't increase the volume and in fact usually decreases it. The speaker is 4 ohms so changing the speaker to a lower resistance (if available) is likely not an option. I get and give good signal reports and have what I believe are good antennas....they seem to perform fine with my other HF rig. The K2 has the cleaner and brighter audio with less noise. If there is not a way to boost the audio my latest thought is to purchase an external DSP amplified speaker with a headphone jack. I had rather not do that as they start at over $100 and up to $250. Any thought or ideas would be helpful and appreciated. Off forum email replys are fine. Thanks and have a great day!
