Santa Arrives at SolderSmoke HQ! Rigol and Black&Decker

Santa Claus obviously heard my distress call when the TEK 465 gave up the ghost.  This morning it was replaced by a RIGOL digital scope.   I'm going through the tutorials.  Wow, lots of features.  A Black&Decker jig saw also arrived -- this will help in my cabinetry efforts. 

Last night just before dinner I talked to Kiyo, JH1MDJ, in Tokyo on 17 meter SSB with the 5 watt BITX.   I kind of broke through a small pile-up and we then had one of those "please repeat your power level... I can't believe that is 5 watts to a dipole" conversations.  

Happy Holidays to all!

  1. Tell them its 5000mW and think up a "power-name" for your dipole, or tell them the wire is Oxygen Free!

    Saving those for April 1st - but you can borrow them.

  2. Yea, that oxygen free coax is expensive, but it really helps! The other day I heard this on 17 meters: "My friend is having trouble on 60 meters. His rig works on some channels but not on others. I think it is because he is running a 1/4 wave dipole. I told him that he should put up a half wave dipole so he can cover the rest of the band..." Hmmm.

  3. The 100MHz DS1102E is a much better value (sorry to spoil the parade). There is a firmware "hack" to turn a DS1052E into a 100MHz scope, but it is pretty old now and requires downgrading your firmware to a previous version, which has drawbacks of its own. As a rough rule of thumb, your scope BW should be around four times the frequency of the signal you are measuring. So for HF work, a 100MHz scope just about cuts it.

  4. Every dark cloud has a silver lining. The 1052E broke! So I sent it back and ordered up a 1102E 100 MHz replacement.
