  33. Subject: Kenwood ts-820 questions
  34. To: info-hams@ucsd.edu
  35.  
  36. HI, I have several questions regarding my Kenwood TS-820 (with
  37. digital display)  I am hoping you can all help me with this...
  38.  
  39. First, I am looking for some accesories.  I don't have lots of money
  40. so trades would be nice however I can supply cash if required..
  41.  
  42.         I am looking for the following: External VFO, 2 meter transverter
  43.         and dc power adaptor.  If you have any of these and want to
  44.         get rid of them please let me know.
  45.  
  46. I would also like to know where to get replacement output tubes for
  47. this radio.  Considering its age, I figure it would be a good idea to
  48. get a few while the getting is good.  What type of tubes does this
  49. radio use?  What brand/type would make the best replacement?
  50.  
  51. Now for some tech stuff..
  52.  
  53. I would like to know how to control the power output of the radio
  54. during vocie transmission.  I know how to on CW (Just reduce car) but
  55. I don't know the proper way to do this on voice.
  56.  
  57. My radio does not seem to put out its full rated 200 watts.  Any
  58. ideas on this or any way to test it.  It is possible that my MFJ d
  59. eluxe versa tuner II power meter may be innacurate.  I have been
  60. told not to trust the readings on these meters.
  61.  
  62. I have a Cmos super keyer II which is NOT compatable with the negative
  63. switching on the Kenwood.  For any of you that have this problem, I have
  64. found a simple fix, here it is.
  65.  
  66. 1. remove the phono plug from the end of your keyer cable.
  67.  
  68. 2. Reverse the wires, soldering the origonal center wire to the outer
  69.         connector of the plug.
  70.  
  71. 3. To the center plug insert a resistor whos value is high enough
  72.         to reduce the voltage presented to the keyer terminals (use a VOM
  73.         and voltage divider equation)  I used the higest possible value
  74.         that still allowed the keyer to make the radio transmit.
  75.  
  76. 4. Solder the remaining wire to the other end of this resistor.
  77.  
  78. 5. Attach a diode across the terminals.  This protects the keyer
  79.         transistor from any potential spikes from the transmitter. (got
  80.         this from the Art of Electronics)
  81.  
  82. 6. Thats all there is to it.  I placed the resistor and diode right
  83.         in the case for the phono plug.  Use some heat shrink for short
  84.         protection.
  85.  
  86.         This seems to work fine and has not melted my keyer yet.  If
  87.         anyone has any comments on this or improvements please let me
  88.         know.
  89.  
  90. Finaly, I would like to build a field strength meter.  I was thinking
  91. that an opamp based circuit would be ideal for this.  If anyone
  92. can help me with this I would appreciate it.  I know I could buy one
  93. cheaply, but I would like to build my own.
  94.  
  95. Thanks in advance for any comments or suggestions.  Please email your
  96. answers to lvin@cosmic.physics.utah.edu
  97.  
  98. I will summarize all responces.
  99.  
  100. Thanks again
  101.

  160. Subject: Scratchi, January, 1960
  161. To: info-hams@ucsd.edu
  162.  
  163.   I ENJOYED reading Myron's posting.
  164.  
  165.  
  166.   Scratchi was previously totally unknown to me, so I just read what was
  167. there.
  168.  
  169.   I interpreted it as a commentry on the different interests and
  170. viewpoints of different generations. It said that two different
  171. generations do not understand each other, and can fail to predict this.
  172. It did not seem to attack either generation.
  173.  
  174.   I thought there was a strong element of lampooning old fashioned
  175. stereotype characterisation.
  176.  
  177.   Perhaps Myron's parody is a little too subtle for everyone to
  178. recognise it ? Even if he now states his intent, no matter what that
  179. intent was, not everyone will believe him. We will never know with
  180. certainty.
  181.  
  182.  
  183.   Foreigners and children have the ability to see things, and ask
  184. questions that are too fundamental for others to notice (or dare)
  185.  
  186.    Cheers

  335.      by the Penticton Radio Observatory (formerly the ARO from
  336.      Ottawa).  High solar flux levels denote higher levels of
  337.      activity and a greater number of sunspot groups on the Sun.

  575. Just to point out that the Scratchi column was controversial during the
  576. time it was being published too.  I distinctly remember an exchange of
  577. letters to the editor arguing over the point.
  578.  
  579. Anyone remember the "Heinrich Schnibble" items from Saturday Evening Pest of
  580. the same period?
