Lincoln S-meter

[Rogerbird1]

Hello,



What is the output power of the radio on AM and SSB?



Can you check the RF Power meter when keyed into a Dummy load?

Does it go all the way up?



Does the SWR meter CAL adjust?



What is your SWR on your antenna (using an external and the internal meter)?

Is this a new Lincoln, with the MRF 455 final or an older one with the MRF477 final?

Sounds like the meter is out of cal..

To adjust the RX S-meter its VR101

To adjust RF power its VR115.

You should check to see if it is throwing a carrier when it does that.

It is a common problem and easily fixed,but can burn up your radio if it is happening...



Its called "the Weird Dead Key Problem" (YaesuTom)

I just got a new chipswitched Lincoln and the s-meter dosent seem to be reading right..... I was talking to a guy that said I was giving him a solid 9 and I was only getting about a 2 on him....He was really booming in but the meter didnt show it. Also when in AM mode and I key up with the Varible power at max, the meter only registers about an 8 or so... It dosent go to max like alot of S-meters. Is this normal??Any suggestions??The only mods done to this are the chipswitch and the channel guard. Other than that it hasnt been touched

Thanks

Yep a watt meter or SWR meter on Cal..



If it is throwing a dead key with output (you will see it best on AM)



to fix this.. unsolder one side of the 2 piggybacked caps on the bottom side of the main board, connected to the Final.



It is the 34MHz pull off caps (2 connected together) it can cause the 'Weird dead key problem' .. It will not harm the radio to disconnect these.
