[Drakelist] R-4C Antenna Input Direct To Mixer

Hi to all: This question has to do with the antenna input for the Drake R-4C. Has anyone tried bypassing the RF amp and feeding the antenna input directly to the first mixer in the R-4C? 73, Chuck___ Drakelist mailing list Drakelist@zerobeat.net

Hi to all Drake fans: Do you think the Drake R-4C could be modified to accommodate one of these two class A audio amps and the graphic equalizer? At present I don't have the schematics for these products. Here are the three links to look at:

Hi Curt: Remove the balun and try again without the balun.  Use low power to see if there is a change.  And, remove the balun and replace with a homebrew balun and try again.   I did a test on 160 meters and the balun got so hot I could not touch it.  Balun damage is not restricted to 160

[Drakelist] R7 transceive with T-4XC???

Hi to all: Can the Drake R7 receiver transceive with the Drake T-4XC transmitter?   Or, would I have to use the mute button on the R7 before transmitting? 73, Chuck - AA5WG ___ Drakelist mailing list Drakelist@zerobeat.net

Hi to all:   A couple of days ago there was a very loud crack, pop or bang then some continuous crackling that came from the speaker.  I was in the next room when this happened.   At present, the receiver will not receive.  The S-meter is pegged to the right.  When turning the radio on the

[Drakelist] T4X-C Won't maintain output

Hi to all: After aligning the T4X-C the power output is equal when switching between R4-C or T4X-C control via the transcieve switch on the transmitter.   Now, the output is lower when the transcieve switch is in the T4X-C position.   This is for 80 meters.  I aligned the transmitter again and

[Drakelist] T4X-C. Now more output power and no RFI?

Hi to all My T4X-C always  put out about 110 -120 watts, less on 20 - 10 meters.  On 40 meters there was always RFI problems with our organ.   Today, the T4X-C was putting out 150 watts on 80 meters.  All the other bands had much more output power too.  Amp meter said 400 - 450 mills.  320 - 350

Hi to all: This is a T4X-C question.  I have a C-Line and I am giving the T-4XC an alignment    (R-4C too).   (1)  80 meters challenge:  80 meters has lower output than all the other bands.  I noticed three of the four alignment trimmer capacitors on the left side of radio (T-4XC) are
