[1000mp] Antenna Tuner / RX Problem

[Norm Bryant]

Concerning the Yaesu FT-1000MP Mark-V. My radio was bought new and has just completed two months in service. A problem has cropped up concerning the antenna tuner and the receiver. After keying the transmitter I am losing almost all of my RF signal in receive mode. White noise is still there, but it is as if I had unplugged the antenna from the transceiver. My s-meter drops and doesn't show any signal. The attenuator switch doesn't change any noise levels. NB makes no audible difference. If I hit the Tuner switch a few times, it may bring my signal back. Then, all it takes is a quick keying of the transmitter, and I'm without my receiver again.There has been no changes to antenna or anything in the system. It has been working well for two months, and suddenly this happens.

I read about the 39 memories of the antenna tuner, and I tried the 'sub ce' and 'ent' thing while bringing it back up...several times...but that didn't help any. In fact, I'm not even sure that the antenna tuner is working. I used to hear a motor noise in the unit from time to time, but that is no longer there at all. I looked at the menu (# 8-8) and checked to be sure that the antenna tuner was in fact turned on, and had not somehow been turned off accidently. It is fine, according to the menu.

Frankly, this is my first Yaesu product, and a big one. I hope this company will stand behind their product if something has gone out. I sent an e-mail to the Tech Department at Yaesu last week, but no response as of yet.

Just curious, but does anyone know if this specific problem has this problem been encountered before?
