A few readers of this blog may have been surprised to contact me on a new mode last night…RTTY.  I’ve tried radioteletype once before in the past (also in the NAQP contest) but rather unsuccessfully the first time.  The second outing was a bit better.  I suppose with practice it becomes fun, but the primary motivation here is ARRL’s Triple Play award for contacting all 50 states each three times, using CW, SSB, and digital.  CW was, of course, easy.  And, I’m making good progress on the SSB totals.  So, I figured I would stop putting RTTY off and give it a shot.

As you are probably well familiar, I normally contest with two TS-930s.  Their prior owners (who were CW contest/DX types like myself) made various “improvements” to them, most of which I appreciate, but I have no idea how they affect FSK. One radio simply does not work on FSK (need to look into this) and the other has the passband shifted about 50-100 Hz off-center of the normal RTTY frequencies. So, when I was running AFC in MMTTY, it would “walk” to the point that having a lock on the other station would put me at the edge of their passband. I had a terrible time making QSOs for the first hour until K0TI told me I was off-frequency (thanks, Dan!!!) and then I started paying attention to all of the numbers in MMTTY and turned off the AFC, which had some deleterious effects that I overcame thanks to the occasional repeat. Typical analog op becomes digital lid op.

I sent the MacBook (our “home” computer) with Sarah to a conference yesterday.  Since that’s the only place I have LoTW’s Trusted QSL installed and I failed to export a .p12 file, I’ll have to hold tight for a couple of days until they return.  (This is not entirely true, I have an old .p12 file, but I haven’t backed it up again since I renewed the certificate a few weeks ago.  Bad backup practices…although I just got a new external drive so the old drive can be used to do a Time Machine back up…finally.  Another day, another project.)

This post mostly mirrors my 3830 post, but here are the numbers for the curious.  My grepping missed one QSO on 80 meters when I did the totals (N1MM rounded the frequency up to 3600 kHz) for 3830.  So, these numbers are right, aside from log-checking discounts:

Call: K8GU
Operator(s): K8GU
Station: K8GU

Class: Single Op LP
Operating Time (hrs): ~3

 Band  QSOs  Mults
   80:   37    21
   40:   58    27
   20:   35    18
Total:  130    66  Total Score = 8,580
