    Great stuff

    Thanks for the good video. May I ask where can I get the schematic showed around 37mins? There is more info in like telling which part is mod meter and so on. Would be very nice to know what part is what like in that manual! Thx in advance
    (Working on mine at moment but not to much luck for now)

    Worst problem I find with these is all the corrosive glue in the final section. Last two I did had dead shorts the glue was so conductive.

    • @TheDefpom
      @TheDefpom  7 лет назад

      Yeah, I have been picking it off carefully, I found heating it up with my hot air station softens it easily making it much easier to get off, someone had already removed the glue from the voltage regulators on the MPU board.

      Unfortunately what I have been seeing lately in these has turned dark brown and is hard as a rock. One of the last ones I did had corroded the wires off 3 of the coils. Hate having to rewind those.

      I have several original service manuals. If you want better scans of the board layout let me know.

    • @TheDefpom
      @TheDefpom  7 лет назад

      Yes, high quality scans of the diagrams would be nice, especially of the board layouts.

      HI
      my name is mark i have a hr 2510 tx is ok but no receive in all
      modes.I can trace my signal am to d111 and 112 but not at q109 i change
      ic 101 but still no signal at 109 there is one thing at ic 101 agc pin 8
      and 10 have 6.8 voltes at all times squelch on or off no change.the
      signal meter indicate a signal. problems found q103 d117 d111 was open i
      replace them all voltages in the transistors in the receive chain read
      ok change the two 47uf capacitors any suggestions would be greatly
      appreciated thank you very much Mark

    Hi, my HR2510 doesn't retain the last frequency after switch off, no battery present, how can I fix it? THANKS

      I have done reviews on a few different ones, the best by far was the Pros Kit which is now my main unit.

    sometimes a recap fixes everything :-)
    that output power you showed. thats suspect, someone has been in that radio turning things that shouldn't

    • @TheDefpom
      @TheDefpom  7 лет назад

      Yep, otherwise it seems OK really, I dropped the power to 7W AM/FM to reduce the chance of blowing the hard to find final transistor !

    Great video Defpom. I have a question though. Not sure if you still work on these, but I recently inherited one of these old rigs when my father, N1CSS passed away and I'm trying to fix it up. It hasn't been used in a very long time, and I'm not sure what was wrong with it when he put it away. But anyway, I can't get very far with testing, because the power is a dead short! I removed the glue and even REPLACED both regulators, and no love - still shorts out. Any suggestions?

    can you do a video on aligning the freq, I have a hr . love the old radio . had it for years. and the shown display is off from the freq. is there a simple fix with just a pod ?

  • @randybehrmann5454
    @randybehrmann5454 6 лет назад

    I'm in the states. I need to replace the memory super capacitor on an HR2600 and I have had no luck finding which one it is. Would you be willing to let that information out into the wild?

    • @TheDefpom
      @TheDefpom  6 лет назад

      Randy Behrmann - I don’t remember exactly where it is in the 2600, but look for a very low voltage (I think it was about 2.7v, but will certainly be less than 6v) and very high value cap, on the MPU board close to the big MPU ic. I’m not near a diagram at the moment so cannot tell you the exact values.

    I've got an issue with my Lincoln. Today the AM and FM TX has died, but SSB is ok. The radio receives on all modes. Are you able to advise which areas on the PCB I should be checking out? I suspect a component has failed. I;ve had the radio for years and this is the first time it's had a fault. Many thanks! JC

  • @kdx-pn7up

    Hi there, don`t know if you can help me but i have a Mk.1 President Lincoln that i bought cheap off Ebay. It was stored for many years not being used so when i got to fire it up all seemed OK, its got RF power "about 17w" am-fm. BUT NO modulation !!!! Done the DE-glue and now have about 21w but still no modulation...checked the standard mike and that seems fine, any ideas ??? Thanks Chris

    • @TheDefpom
      @TheDefpom  6 лет назад +1

      30ok777- it is probably a bad electrolytic cap in the audio circuit, lower your rf power down to 10w am, you really don’t want to blow the final as they are not made anymore.
