    ASTROPLANE best vertical antenna ever?

    No, circumstances changed and antenna had to come down. Better is very subjective. In the 80s I had it up on a telephone pole and it couldn't be touched. There is bigger. But better? All depends on what you are after.

    ASTROPLANE best vertical antenna ever?

    For the longest time I had an original Astroplane in a pine tree. I actually brought it up with the hoop off and assembled the hoop around the tree. So the antenna was actually in the tree and not above. Had a mast coming down lagged into the tree with Stainless. Worked great with perfect swr...

    Uniden Wireless Microphone

    I have used this mic on all different radios with adapters I made. The 2 best sounding on tx audio were a trc457 and a Yaesu ft101e. No matter what radio you use it on there is a slight hum noise on tx and the closer you are to someone the more they hear it. It's the nature of the beast. People...

    Cap kit arrived today. Will change out all the caps this weekend and report back. Thanks Klondike for the great service.

    Trc457 modulation clicking

    No. It is only on the channel I'm talking on. It's not like a clicker click with a dead key. It's more like the alc limiter is kicking in on high.

    Trc457 modulation clicking

    No beating up. I truly appreciate all the help. AM has the click. Not so pronounced like on ssb but with a whistle I hear it right at the beginning of the whistle. Where on ssb it is there with every peak clear but under the voice. PA is clear as can be with no click I could hear.

    Trc457 modulation clicking

    Later today I will check it on AM and the PA. Yes the .1 is original. This radio was a virgin when I got it. Never had a screw out. Everything is as factory.

    And the cap is a .1 not changed to a 1uf.

    Trc457 modulation clicking

    Ok, I pulled alc transistor out of circuit and like you thought it's worse. I checked the 8v for sag and it's solid. I do not see a diode going to the cap from pin 2 of the ic.

    Trc457 modulation clicking

    I replaced the big cap in the power supply just because and the tantalum in front of the relay that is a known one to give problems just because. The radio was working good except for the clipping.

    I have not removed the limiter. Only turned up the alc. What should I remove to test if it happens without the limiter? I will also get the board number when I go back into the shop. This radio was virgin. Screws never removed until I got it.

    Trc457 modulation clicking

    And the sound is low under my voice. Not cutting my voice out.

    Trc457 modulation clicking

    The relay is not dropping out. I had a brand new nos relay here and popped that in just as a test. Same clipping. Audio is loud and clear on ssb just has this clipping sound with my voice peaks

    Trc457 modulation clicking

    Ok, I had a new 1uf 50v here so I swapped out c158. Same thing. Clicking with my voice. Really hear it with a whistle. Sounds like clipping

    I have a cap kit coming from Klondike so I will swap that one out first and see what happens. Thanks Chris
