Astatic PDC2 SWR/ RF Field Strength Meter Questions & Answers
Which astatic d104 unamplified mic is compatible with a tram d201
ALL D104 microphones are high impedance devices. It is the mic stands that are different. The non-amplified stands are intended to work with tube radio equipment. The transistorized bases are intended to drive solid state transmitters, but will also drive tube equipment. The D104 microphone with the non-amplified base will work well with this radio as it has a very high impedance input.

Check out this website www.qsl.net/g4wpw/astaticbook.pdf. It should help you out. Also, your D-104 should have the amplifier in the base. You'll see a hole in the base with an adjustment beneath it. You will have to adjust your transmit level with this. Make sure that you have a battery installed!
My palomar 225amp online it arrived w/ a 250 black faceplate.Amp lks new & pills and board look new. Running a galaxy959 it wrks grt. SWR 1.1 on wilson1000. Lights work, preamp wrks. No transmit?
there is your problem . You bought it on ebay ,paid twice as much as it is actually worth and you got screwed . Now you have to get it fixed because you bought a broken piece of equipment. If you have another radio hook it up to the amp and see if it works . Maybe the amp don't like your radio? If it doesn't work then we know its the amp so now treat it like another radio and look inside to see if anything is out of place or maybe burnt , from ebay . You might need a multi meter to do this . check all your voltages and make sure the amp has continuity going from pl to pl set your meter to ohms and insert the probes into the hole on each pl . that will tell you if there is contact . Now you should get a schematic to check out all the voltages of the components inside . It just might be that the amp is drawing to much or not enough amps to run it . I am confident you will find the problem and get it fixed .
How does a astatic pdc1 meter work
As you have the meter in your hands looking at it ,on the right you will see the letters ANT. for antenna .this is where you attach your antenna wire . Now you need a jumper wire to attach to the side that says TRANS . Attach one end of the jumper to the meter and the other end to the radio .make sure the meter is on SWR set the meter to forw and key the mic. now use the knob to adjust for set. Now set meter on ref and key the mic. the number you see is your SWR This should be done on channels 1, 40 and then on 20.for a mid band SWR.
How to wire an astatic 877hl to a kenwood ts 930s
download the trios manual and connections chart then connect the black and screen to the ground of the plugin socket using a bridge wire ie connect black and screen on the mic then connect them to a small bridge wire then to the ground pin and also the moto plugs metals then usualy white or yellow is audio and orange or brown it TX switching
you can use a multimeter and connect its negative to the ground and set the meter to beep test or low ohms then as i say orange or brown press the TX pedel a low ohms or beep indicates the TX switching the rest is carefull wireup just be warned most ham radios will supply 12v or 9v to the mic socket up and down etc if you have these controls are data so will just read like 10k when pressed relative to ground so you need to set the meter to 20k range etc to get these controls
good luck and post how you got on
What the power to to mo sparkmatic5100 cb radio
1N148 , should be located where the electrical power wires come into the radio. try replacing it and it should work. also put a fuse on both wires that give your radio power. then you should never blow another fuse.
