The audio from my HP1 seems pretty choppy. I am holding the channel on the main dispatch of my local PD. Here's the symptoms:

1. lost transmissions, I can see that something is happening based on the channel indicators brightening up
2. Hearing a given transmission, it cuts off midway, or I don't hear the response between Dispatch and field units
3. the signal strength indicator blinks between one and two bars (out of five).

Squelch and range are set at the midway points.
Atten is turned off

I'm no technician, but my guess is either a bad antenna connection. I thought I had an issue with perhaps the internal speaker wiring but after checking it with my ear phone, I get the same choppy results.

Any thoughts?

2 bars should be enough for squelch - 3 max, IMHO.

Digital systems yield the greatest possibility of distorted or choppy audio due to conversion of the digital data stream received to analog (what you hear on your speaker)...think of playing a scratched music CD, if the data is damaged the music is lost or choppy. Due to radio wave propagation (fading, multipath, etc.) the data received can be compromised even though you have a good signal. Commercial quality radios usualy have software schemes to minimize these effects...hobby radios are a good compromise for the price but not able to yield 100% audio quality. Essentially garbage in..garbage out.
Hope that helps...

I sent this same question to Uniden. They told me to try a new ant or send for repair. Sure wish they would have given me a better answer than "try throwing some money at it randomly", which is how I interpret that answer.
