RCI-2950CD owners chime in.. new owner here

I run a 575 on my 2950DX. I added buttons for the up/down to the mic.

Added a new MFJ SWR meter on output. SSB rings just under 300w when whistling at 1:30 power position on 2950. Comes in at 19w without amp on again when whistling.

AM RMS reads 110w at 7am low power setting. Which I know can't be right..

Mainly got for the SWR meter and SSB

Why is the AM reading not right?

Have no idea. On my other MFJ it said the same for DK..

110-120 would be high. Supposed to be no higher than 80 I heard for the 350..

I checked without and at like 8 am it's 2w output from 2950. That's all I worry about. And the TS350 meter is at 6 which I heard is proper spot for a DK.. swings a tiny bit like 6-7 on the TS350 meter.

Any one see a rf output drop off on 10 meters?
Full output on 11 meters, go to 10 & down about 50%
Antenna is fine, even shows same on dummy load.
Any thoughts?

my guess is it was retuned for 11 meters

supposed to be NIB? That was my first thought also.

Maybe now Ranger is tuning with EChip in place and then removing prior to shipping.

Everyone is telling me my 2950 is dead nuts on for 11m SSB..

In other news with power knob down at 8 o'clock and my TS350 V in variable mode I'm doing a 60w dk with the TS350 variable knob all the way up.. running 45-50w with power knob all the way down on the 2950.

With the 2950CD at lowest I see a 2.25w dk on the MFJ-822. Which has a 2w minimum per the spec sheet.. At noon position I'm showing a 10-11w dk.

The TS350 meter is showing 4-6 when modulating in AM.. vs the 6-7 without the variable on. Also double checked MFJ is showing a flat 105-110w dk without variable knob on..

All the videos I have seen just say run with knob all the way down for AM and all the way up for SSB when running a 350..

I run my SSB at like 1 o'clock.

I am running 13.8vDC power supply.

Now you see why it's not ideal to run an amp with a radio that can easily over drive it.

It really sounds like your dead key is a little higher than the amp likes. Also, you really can't measure a 2.25 watt dead key with that meter into an antenna and expect it to be accurate. It is pretty much a decent guess at that point.

I'm not seeing the modulated output on AM, so it's kinda hard to say what to do. You could try turning the variable on with the amp all the way up and adjust the power at the radio to get the dead key you are looking for. Unfortunately the Texas star variable pots are known for burning out when used. Can't really win I guess.

May adjust AM low pot inside to lower about more..

I always heard the pot on the TS was a weak point. Both my old T stars had em and I never turned back off wife open. Always adjusted output of amp with how much drive I put into it.

When I had my 350 hdv back in the day at some point or another that stupid pot was replaced with a two position switch with some heavy-duty resistors behind it.... that's what I used on AM...

 

[CB590]

Running 90 percent sideband. Which is working great thus far.

When I have time I'll just lower than AM low pot inside the 2950

I adjusted my 2950DX to 1/2 watt low and 3 watts all the way up on the dead key. I don't want to rick blowing the driver on my 667 by having too much dead key by accident.
