- I have several friends with "after market" antennas on their 580's,
- while I have always used the origional. We have never noticed any
- differnce. ANY shortened antenna is NOT going to work as well as a full

- Co-ax cable isn't just used as a transport medium, there are also some
- low Z cables made for use in transformers.
-
- These live in specialist manufacturer's catalogues and often don't have
- Radio Guide numbers.

- What you are hearing is <S>ingle <S>ide <B>and, commonly called SSB
- which, unlike the broadcast signal you can hear well, has no carrier.
- The carrier has to be inserted at the receiver. It (the insertion
- device) is called a <B>eat <F>renquency <O>scillator (a BFO) which
- reinserts the carrier at the receiver. If you want to listen to the
- stuff, you will have to get a communication receiver. 99% of the
- conversations by voice between Amateur Radio operators (Hams) between
- 1.8 and 30 Mhz is on SSB.

- Actually this radio changes the digital display in only 10 khz steps.
-
- Is there a DSP algorithm that could be used to render intelligible speech
- from the mistuned signals?
