   In a message on 12-08-18 Ed Vance said to Holger Granholm:   
      
   GE Ed,   
      
   EV> When I saw the word 'detector' I thought of the RX portion of the   
   EV> XCVR.    
      
   Yes, of course, the detector belongs in the RX portion.   
      
   EV> Where I wrote AM or FM I was thinking about the TX section.   
   EV> Balanced Modulator or something like that.   
      
   To create FM you vary the oscillator frequency either directly or by   
   changing the phase (Phase modulation).   
      
   EV> Before the Kenwood TR-9130 went belly up, I used it on FM, SSB and   
   EV> CW. Can't remember if it had AM for a Mode or not.   
      
   I think most HF transceivers incorporate AM but not the VHF/UHF sets.   
   In my shack the Drake TR-7 does have an AM, as well as a RTTY position   
   on the MODE switch but none of my VHF/UHF do.   
      
   I have both Icom and Yaesu/Sommerkamp tcvrs for the VUHF bands.   
      
   EV> My other 2 M rig is a Regency HR-2.   
   EV> Once in a while I will turn it on but haven't heard anyone talking,   
      
   EV> I havr XTALs for .46 and .52 Simplex in it.   
      
   Oh poor lad. XTAL control went out the door ages ago.   
      
   There's very little traffic on the 2m and 70cm repeaters here.   
   The reason is of course that OH0 is quite a small area and everyone has   
   talked to everybody else and there's not very much to talk about then.   
      
   In the summer the activity rises due to the tourists that visit the   
   land Islands.   
      
   EV> I've read that that 'feature' is used where two Repeaters are near   
   EV> each other to only accept the Tone that sites RX has installed in   
   EV> it, to cut down Interference.   
      
   That's correct. Here we have repeaters that can be accesed either way.   
      
   EV> If You have Your magazines stacked in order grab the December and   
   EV> January issues for several years back and see if a Indes is provided.   
      
   Yes I have the "UKW Berichte" and their yearly index is in the january   
   issue. The CQ DL magazine I borrow from the club but IIRC the index is   
   in the December issue.   
      
   EV> Thank You!, I haven't found My ROUNDTUIT to do that Search yet but   
   EV> will have a look-see...........   
      
   Look for a 9600 bps 70cm (430 MHz) packet transceiver.   
      
    HG> All repeaters here sign their callsign with morse.   
      
   EV> I remember hearing the CW ID, I'm thinking I've heard one of them   
   EV> have a Voice ID, not sure.   
      
   Yes, some do. One of our repeaters does have a VOICE ID too.   
      
      
   CU AGN, Sam, OH0NC   
      
   aka Holger   
      
      
   .. Can't use Windows.  My cat ate the mouse.
