That is correct. Rob, NC0B

Mark, Thinking about this more... Forget that last analysis, I think your carrier oscillator is fine (and you indicate you did the manual alignments). Your audio on the panadapter does look good on

I have a D-104 that I use with various radios. I always get good reports. The secret? It has a JFET source follower in the base. The JFET presents an extremely high impedance to the Rochelle Salts

Mark, Ah ha...? I just looked at? the original post. I think you have a problem with your carrier oscillator alignment. When you look at your signal on the new rig with the panadapter... When you

I just sent a rather long note. Try the attenuator pad first, the mic may be overloading the mic preamp. However, the mic has a characteristic pinched sound, to my ears metallic. Look at the frequency

A Note: This data sheet shows an attenuator pad, if you don't want to by-pass the amplifier I strongly suggest you use this pad. The white wire referred to is inside the base. The D-104 has been a

Yep. It’s in the manual. The two grounds get tied together at the connector. Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a banana. Sent from [Proton

Hi Richard, Yes, this is an amplified version and I wanted to try it at a low setting as my audio reports have come back as pinchy and narrow. Bill N1WL ?? William Losefsky? ?????????

It would be helpful to remove the three screws from the bottom plate of the D104 and attach an image of the wiring and to determine if you have an amplified base. One goal is to isolate the audio

Is this an amplified mic, sound like it might be. The T4 (any) does not need an amplified mic. The mic connector on the transmitter has three active connections: Tip=transmit switch, Ring=Audio,

Ok, but to get to the basics, is the very tip of the plug the PTT?Is the middle of the plug the MIC?and is the shaft GRND? ?? William Losefsky? ????????? CallSend SMSAdd to SkypeYou'll

Bill, I’d ring-out the connections with an ohmmeter. D-104’s have been around a long time and who knows how many times the wiring may have been changed? Steve Wedge, W1ES/4 Time flies like an

Remember also that the accuracy of the frequency readout is +/- 1kHz. I think we have all become accustomed to super-accurate readouts on our newer gear. And yes, that approximately 900 Hz offset is

Folks, I have a Drake T4XC and trying to figure out the D-104 wiring onto the Drake plug. Lots of stuff on the net and much of it conflicting. Here is the color code of wires coming off the D-104 Blue

Is it acceptable to advertise a TR7 for sale on this group? Thanks Dave G4FAW

OK, here is what I would do. First, thoroughly inspect the area of the oscillator circuit with a magnifier and good lighting. Look for suspicious solder joints (especially where a connection is made

Thanks Gary! That makes me feel much better. Will try it and let you know the outcome. Really appreciate the help! Mark -- Mark "Fleisch" Fleischer *KF?KZP* *Public Address Announcer/Voice

I am looking for either a 2CS speaker or 2CQ Q Multiplier for my 2C receiver, if anyone has one for sale or knows of any for sale. Thanks, Rick NJ5W
