I have a 151.015 collar that appears to be affected by the Dc 30. The beeper slows down to a very slow week beep.................beep................screeeeech over and over. This collar seems to be ok without the dc 30. Any ideas? Terry

The 2 signals may be walking on each other. The screech you are hearing is most likely because you are picking up the stronger DC30 signal.

Thanks Steve, there is definately something going on. Three out of five collars are affected. This will make for a pretty poor emergency back-up system. Terry

Terry, I'm guessing this is only at close range right? Since the interference of the VHF signal should go done at further ranges with the CW unit not being able to pick it up. What type of tracking box are you using?

I had two beep collars that I thought for sure made my DC30's lose signal. I messed with them enough to convince myself that I should just sell those two collars. They were a 150.955 and a 150.985. The rest of my 150 collars are fine.

Steve I have a Wildlife TRX 10s reciever. The issue is when the DC 30 and tracking collar are right close or touching (dogs neck is not long enough) a friend had the same issue today and it seems to have nothing to do with the reciever.

Buzz I had not even thought of it bothering the DC30s but come to think of it I have had issues with the 30s loosing satialite connection. Thanks Terry

i was told if you cross the two antennas they wont interfer i put my telementary pointing to the right of the dog and the garmin pointing to the left i was told this but never had a problem worth a try

DON'T CROSS THE STREAMS!!

Actually there may be something to that. By putting them opposite of each other. It may keep the radiation patterns from conflicting with each other so directly.

IM NO ELECTRONIC GEEK, BUT ON PAGE 55 OF THE ASTRO 220 MANUAL UNDER RADIO, THE "MURS( MULTI-USE RADIO SERVICE) FREQUENCY MAY HAVE SOMETHING TO DO WITH THIS? THE FREQUENCIES ARE; 151.82, 151.88, 151.94, 154.57, 154.60 MHZ. IF I UNDERSTAND THIS CORRECTLY, I THINK THESE ARE THE OPERATING FREQUENCIES OF THE ASTRO 220 AND DC30S. SO I THINK IT IS THE FREQUENCIES STEPPING ON EACHOTHER. THIS IS PROBABLY ALSO WHY GUYS ARE BURNING UP THERE ASTROS WHEN RUNNING HIGH POWER HAM RADIOS WITH THE 150.000-AND HIGHER FREQUENCY BANDS AT THE SAME TIME WHEN IN CLOSE PROXIMITY TO EACHOTHER. IF IM WRONG PLEASE CORRECT ME!

Shadow, there is no thinking needed. It is a fact. Even more so when one tries to use radios transmitting on the same channels. With the collars though. It should not be as bad since collars use the CW band, and the Astro is using VHF. Still any radio transmitter within close proximity of a reciever of any type does pose a problem for bleed over. As many have seen with TV's and CB's.

WASNT TO SURE ON WHAT BANDS THE DC30 RAN ON, I HAD THE ASTRO MANUAL NEXT TO MY COMPUTER, AND REMEMBERED READING ABOUT THE ASTRO ABOUT A YEAR AGO. I SHOULD HAVE GONE OUT TO STORAGE TO GET THE INFO ON THE DC30S. THANKS

Don't need the manual, or the walk to storage. Just ask, it what we're here for.
