CAT Question

 

I recently picked up a MFJ-929 tuner to use with my IC-706. It came with the cable for my FT-857 so I was going to use it instead of my YT-100. I currently use a USB to CAT cable to control the rig with HRD since my current tuner has a CAT pass thru port. Has anyone had any experience with using a splitter to run both the CAT and tuner off of the rear CAT port? Is it even possible? Any assistance would be appreciated.

73,

Brian

Short version is the AGC was turned off and RF gain needed adjustment. Probably most of the problem was related to the AGC being off.

Re: AM Broadcast Stations Distorted - Found IT!

Dennis Yard
 

Gents,

Thanks so much for your suggestions. ??

I just found out that the RF Gain was not right for the AM broadcast signal level.? I must have adjusted it during SSB operations, when moving from FM repeater ops.?

What led me to the solution was that the signal got a bit clearer when I activated the Attenuation button.? So I went and adjusted RF gain and got it right again. ?

Re: 857 stopped powering up; NOT a 12v source issue

 

Jason,
I've had this with mine as well.? One instance was a sketchy fuseholder (the inrush current I-squared-R loss dropped the input voltage below 11.5VDC). Was the car running and VDC > 13 VDC at the radio?
Second instance was a bad remote interface cable between the head and the pan. when the control head was connected with the pan using the short cable, it worked fine.? I replaced the longer remote cable with a hunk of cat-5.? Been working fine ever since.
Good luck!

Try listening to WWV on 5, 10, 15 or 20 MHZ on SSB and AM. Is the AM signal clean? If so, then possibly something the LF portion up to 1.8 MHZ in the radio may be bad.
