Re: CRT 9900
Make sure you haven't nudged the voltage adjuster down.

Cheers Paul.
checked that all OK, still saying DC Lo, any other ideas please. I have also put it on my 50 amp supply still the same.

Got the sound back, but still dc low.

Re: CRT 9900
Check the DC lead, the fuse holders, plug & socket assembly.
I have a TS-440 that had all sorts of weurd issues that I traced to a faulty dc lead.
Failing that, I would carry out a full reset.

Re: CRT 9900
I've changed the fuses,10 amp is that enough still showing dc low any other ideas. I might try a new power lead.

Re: CRT 9900
You should use the same rating as you removed but as your radio is powering up, it's unlikely to be the fuse. However, if your lead has poor fuse holders or bad connections at either end, it may not supply enough voltage or current to allow proper operation. If you have a replacement dc lead to hand, I would try that. Do you happen to have a multimeter or voltmeter? If so, check the voltage at the radio end of the cable.
If you are still seeing DC low with a different lead and you are certain the power supplies you have are ok and providing the correct voltage, I would carry out a factory reset on your radio.

Re: CRT 9900
Sounds like an issue with the radio to me. Maybe a setting has been changed accidentally.

There is no such thing as a Fidelity 1000 which is too good to scrap.

Re: CRT 9900
Can you not set those things to display the voltage when you TX? If so, and it reads about right then don't worry about it, or do you get the DC LOW when it should show a voltage? As above, a factory reset won't hurt.

Re: CRT 9900
There's an option in the menu system which is option 7 I think. This is DC voltage protection & in the programming software, you can set an upper & lower setting. Perhaps it's set to low & is triggering the dc low.
You could always try switching that off.
However, question is, does the radio actually work properly in terms of tx/rx?

Re: CRT 9900
Pretty sure you can but you may have to enable it in the software. I will check mine out later to see what's needed.Admiral wrote:Can you not set those things to display the voltage when you TX?

Re: CRT 9900
Checked mine and there's a setting in the software to allow you to show battery voltage instead of the frequency display when in TX.kilimax wrote:Pretty sure you can but you may have to enable it in the software.

There's also a setting, again in software to change the battery voltage protect minimum and maximum levels. Mine is at 10V minimum and 16V maximum.
@nitehawak you may wish to check these and as per another of my posts, you can disable this in the radio menu option 7 I believe.
