increasing sensibility on IC-28A/H
Hi guys,
I observed that my IC-28H rig is a little def. How can I increase the sensibility of my Icom IC-28H? Are there any adjustment to do this or It only can be done using an external preamp? 73, Yvson - PR7BOK |

Been using it since it was purchased new, and I find the sensitivity to be excellent. It is not adjustable. You might want to look at the RF amplifier, Q4. It might have been blown by static or being too close to RF. The service manual is available here. http://www.mods.dk/ Dick - W6CCD |
