Dear Towertalkies,
I am looking for some help for 9N7RB in Kathmandu.
For the second time he has had a control box for the Yaesu
G450-A fail. The first control box worked for approximately
a year and then failed...we bought a new one and shipped out
to him..it has now failed with similar problems.
A couple of questions:
Is this unusual or not for this model?
I can get a defective control box and send it to have it
checked and repaired, but where should I send it?
Is it cost effective? It seems the last time I bought a new
box from Yaesu in CA it was around $150 or so.
I have taken the liberty to quote some of the email where
he gives some symptoms of the problem.

Would appreciate words of wisdom from anyone familiar with this
model and/or symptoms/cures.
Thanks in advance. Sincere 73
