For some time now, you have been able to export coverage maps and directly overlay them on Google Earth graphics. A newly added feature now permits you to adjust the level of transparency you wish to have plotted over the Google Earth surface. The benefit of this new feature is that you can now adjust the density of the exported coverage map to permit desired surface features shown on Google Earth graphics to be easily visible. To see how easily this can be done click here.

  

Sometimes a radio user observes that a radio link does not perform equally well in both directions. Every radio system has two distinct coverage. Talk-out coverage is the received coverage area out from a base (or fixed) station by mobile and handheld radios within the reliable coverage area. Talk-back coverage is that region where the mobile or handheld radio can successfully transmit a signal which will be reliably received back at the fixed location. In a perfect world, all things being equal, those two coverage areas are identical. Since nothing is perfect in the radio coverage world, there is usually considerably different coverage between the talk-out and the talk-back coverage areas. Transmitted power levels, antenna pattern distortion, and receiver sensitivity are almost always quite different outbound from the repeater site from how they are inbound to the repeater from the mobile/handheld unit. TAP can routinely deal with these unique distinctions for each radio system studied. For a very helpful explanation of how to do this, read a new FAQ that is now available. Click here.
