Just replaced a damaged mast for our VHF repeater. Went with a 4-bay dipole as
a replacement, along with switching out the old coax with 1/2" hardline.
Everything else stayed the same, VXR-7000 and internal duplexer. All worked
well after a final check, until night came along, when it seems t
:) Software and cable both reflect COM1...I think I remember having to tweak
with the driver settings but not sure. Could not find this anywhere in the
service manual, any thoughts on what they should be? Baud rate, flow, parity,
etc.

Attempting to program a VXR-7000 using CE-27 (using factory cables & software).
No problems in the past. This time around, gives a read error "invalid data
receive". Also, flashes "CL" and "ON" repeatedly, along with "CLN" on the ANI
display...can't remember if this occured last time or not.
Looking at mounting a DB224 rooftop. The easiest option would be to use
the existing tripod, which is bolted and welded to the steel rooftop.
Any opinions on this? Can't find any data on the tripod as far as
weight loading, etc. Would a heavy duty tripod hold a 20 foot antenna
without a problem

Looking to replace our current VHF Comm. repeater antenna w/ a higher
quality antenna. Orginally wanted the DB series 4bay dipole but not
sure if our current install setup will hold such a beast! Another
thought was using the Antenex series (YDA1504) on a lighter weight mast.

Looking at purchasing a DB224 Antenna for our VHF Repeater. The

Thanks for the response. So this is not what I thought it sounds like. We are looking to boost indoor handheld coverage so our theory was to use this cable with a VHF w/ our main repeater freqs and connect it to a UHF for handheld transmissions. In this case, both radios would need to be able

Just curious.. I've only researched the 4bay DB antennas with one feedline
connection. With the 2 leads, could you possibly use one lead for Tx and
one for Rx in a repeater setup?
