    Palomar RFX95HD

    I believe the resistor value sets the carrier level.

    Palomar RFX95HD

    I believe it wants to see about one and a half to two watts carrier from the radio.

    Is anyone making a new base station

    I wonder what radio the case came from? Maybe a Royce?

    Why?

    Is he going to pay you to fix it again?

    Careful with those lithium battery banks

    Normally water on an electrical fire is a bad idea. Methods that keep oxygen out of the fire are ineffective because the battery generates it's own oxygen while burning. Instead, the water cools down the battery in an attempt to stop the thermal runaway process. In some places, they dunk the car...

    Careful with those lithium battery banks

    Fire departments now bring a full size 18 wheeler tanker to electric car fires. Almost impossible to put out.

    Cobra 29ltd AM/FM as good as the older AM only?

    I believe the only difference is the new one has an FM board added to the AM chassis. That's from looking at the pictures of it. I have not seen them side by side.

    Texas star dx 500v

    My Madison has the Gold Finger wide audio mods done to it, and the D104 has an aftermarket mic amp in it that frees up a lot of bottom end. The radio was originally set up for rack gear, but is on a different radio now. You are right that a stock Madison and stock D104 are not a good match. I...

    It looks like old school super star 3900s are available

    They have the Alinco DX10 too. Everything is in stock and the lowest prices I have seen around. I believe that they are legit, but have never bought from them. I just checked my book marks, and I have looked at them before. I think they changed the color or layout or something. One of the...

    RCI 2950DX

    That is a nice radio, I should get mine out and put it on the desk. Seat time in the shack is hard to come by.

    Amp help

    I was thinking if the amplifier keyed, it might go into oscillations. So the keying relay would trigger, but as soon as it did, the RF would be gone so it would unkey. Maybe the relay would chatter?

    Amp help

    If he had it backwards, it might have damaged the final in his radio. Might not have hurt the amp. Pop the cover and see if anything looks burnt. Maybe hook it up and see what it does?

    Texas star dx 500v

    My best sounding SSB rig is a President Madison with DX 500v and D104 with aftermarket mic amp. Beats out the Icom 718 with rack gear, Stryker 955 or anything else I have been able to set on the desk.

    A Baofeng field telephone for multiple users

    When I was a kid, my older cousin gave me some of his old walkie talkies. The ones that used a CB channel. I was fascinated by all the stuff inside, and all the adjustable cans that had a screw driver slot in them, obviously they were made for a screwdriver. So one day I decided to find out what...

    Stryker 955 channel expansion to 11 meter

    Those radios are pretty good out of the box. And there are adjustments in the service menu to put it on frequency and adjust the modulation among other things. But if it works, I would run it and see what it does.
