I have a VX-5R that squealed when the volume was high.  It was caused by poor contact between the front and back halves of the magnesium case.  Solution was to remove the back, and file the edge of the back where it contacts the front half of the case.  The problem completely went away.  -Kevin

Merry Christmas to all!

Has anyone figured out yet how to enable MARS/CAP?
Has anyone tried the VX-7 Commander software? http://www.qsl.net/kc8unj/VX7Cmd134.zip

Since the VHF marine band ranges from 156 to 162 MHz, it would be useful beeing able to transmit on these frequencies, especially for hydro/amphibian aviation operation.
I would be grateful if somebody could provide information on modifications which could enable this kind of transmissions.

Hi
 I'm thinking of buying a VXA-700.
 From what I can see from earlier posts it seems possible to open up the TX/FM capabilities above 148 MHz.


My question is did anyone try its performance at freq. lower than 144  ?

 We're currently allocated the freq. 137.100 FM for talking to ground crew while towing gliders, it would be nice if the VXA worked well there.  Also in France the FFVL rescue freq. is at 143.9875 FM.

  Is it possible to upgrade(by software) the VAX-700 to also cover these lower freqs.?


Many thanks for answers so that I can decide to order or not order the VXA.

(the alternative is to stick to two radios)

Wondering if anything further is available on how to make the VXA-700 transmit up in the 158 - 160 mhz area?  I am a pilot, ham and in emergency services and sure do need to be able to transmit in this area.

Dear Mr. Felix,
You are correct the VXA-700 does not meet CAP (NITA) specifications.
Despite this, people have been getting them modified for CAP operation.
Their opinion is they can use this radio in "emergency" situations.  You can
get your radio modified by following the procedure below:
 
While the VXA-700 does not meet CAP specification for frequency stability,
there is a MARS/CAP modification available for the VXA-700. This
modification allows the radio to TX and RX just above and below the amateur
2 meter band, within the MARS/CAP range.  This modification cannot be
applied in the field.  The radio must be returned to our repair facility in
Cypress, CA for modification.  Please send the radio properly packaged and
insured to:
 
Vertex Standard
MARS/CAP Mod
10900 Walker Street
Cypress, CA 90630
 
Please include a copy of your MARS or CAP credentials.  Your radio will not
be modified without valid credentials. Also include a note requesting this
modification, your daytime phone number and return address.  Please allow 10
working days for this modification.  Please ship the radio to us at your
cost and we will return it to you UPS 3 day at our cost.
 
Please let me know if you have any further questions.
Thank you for choosing Vertex Standard
Sincerely,
Fred Kix
