8 A New Divison Rover Record Score!
11 <h2> Bdale's Report </h2>
13 The theme for our operation in this contest might be "Roving ala Red Green".
14 Read on for the details...
18 John and I hadn't worked a contest together since January, and he recently
19 finished a DEM 222 transverter and Directive Systems K1FO-style 222 yagi that
20 we wanted to try. So, we planned a modest rover operation for this contest,
21 with equipment for the four bands from 222 through 1296.
25 I pulled a few late nights applying the knowledge gained at Central States
26 this year to tweaking up the amplifier on my 903 transverter. On the bench,
27 it was happily making 10 watts, had a CW detection threshold of about -145dBm,
28 and was within 200hz of true with the TS-790's 2m section as IF after warm-up.
32 We were embarrassed to learn at the Central States antenna range that John had
33 cut the reflector too short on our 903 yagi, dropping about 6dB of gain! It
34 looks like he mis-read his own notes and cut it the same length as the first
35 director. Oh well, it happens. Actually, since we worked everyone we heard or
36 heard about on 903 in the June contest, even with the reduced gain the antenna
39 Kent Britain's designs, and he was running the range, we got some expert
40 assistance adding a metal garbage-bag tie to the reflector to get the gain up
41 where it should be... :-) So, I spent some time in the week prior to the
42 contest cutting a new reflector, and tweaking the antenna. Got the SWR to
43 1.15:1, gain assumed to be ok.
47 While I was at it, I tweaked on our 1296 antenna a bit, getting its SWR a bit
48 better than it had been. John also fabricated a second one which I fabricated
49 a feed for and tuned. Both 1296 antennas got to about 1.7:1 and in the 11dBi
50 range, which satisfied me for roving.
54 Saturday morning, John showed up about 9:30 and we starting putting things in
55 the Trooper. The plan of record was to run the TS-790 on 70cm and 23cm, and
56 use the 2m as the IF for the DEM transverter on 903. John provided his Icom
57 735 and new DEM 222 transverter, giving us four bands total. I bought a 2304
58 DEM transverter kit at Central States this year, but haven't started assembling
63 We stacked the antennas on the mast in my driveway, and proceeded to check
64 everything out as quickly as possible. Everything seemed ok except 70cm, where
65 we eventually realized the Kenwood was only making about 3 watts out, which
66 wasn't enough to drive the Mirage brick to a useful level. After swapping
67 cables and doing all sorts of other things, we finally admitted it was a
68 problem with the Kenwood, and added John's Yaesu 736 to the stack for 70cm,
69 leaving the 790 providing 1296 and the IF for 903. This required a detour to
70 the shop to fabricate some additional power cabling, which took time.
74 Along the way, we worked the antenna-side N connector on my Diamond SWR/Power
75 meter loose, and it quit working right. I've since looked at it on the bench
76 and it appears easily fixable, but we'll see. In any case, before we even got
77 out of the driveway, we'd killed a bunch of time diagnosing the 70cm problem
79 getting the Yaesu integrated into the stack, and had killed the SWR/Power
80 meter. Not a good start!
84 We drove out to our favorite spot in the SW corner of DM89 near Matheson. The
85 weather and operating conditions were good. Congrats to N0KE for being our
86 first-ever contact on 222! We managed contacts on all of the bands we had.
90 After it felt like we had worked everyone we could find, we moved south at
91 about 3:30pm local time to DM88, and set up in a so-so location, pretty near
92 where we've been before. Since we knew N0KE was itching to get down off the
93 mountain he was on and was waiting for us to move, we pulled a Red Green'ish
94 hack and just duct-taped the antenna stack on the collapsed mast to the roof
95 of the Trooper, with the antennas hanging down behind. This necessitated
96 duct-taping the rear door closed over the coax, and caused the 70cm antenna
97 to end up looking like it had been performing mud-flap duty, which it had!
98 This shaved a good 10-15 minutes off our relocation time, and allowed
99 us to catch Phil from DM88 before he shut down for the afternoon. And we
100 figure if duct tape is good enough for Red Green, it's good enough for us!
104 The highlights in DM88 were working N0LL on 432, and giving a couple of folks
105 DM88 for the first time on various bands. Also, we really appreciate K0RZ
106 hanging around and working us on all bands we had in both grids! It was fun
107 meeting Bill in Cedar Rapids at the Central States conference, and we're
108 looking forward to giving him (and everyone else, too!) some new grids on
109 the microwave bands as we get more gear together for future contests!
113 By the time we moved west into DM78, the weather was getting pretty dicey.
114 We had thunderstorms all around us, and only a few stations were still on the
115 air. Thanks to W0AH operating as KI0DF, who was up on Pikes Peak and gave us
116 contacts on all bands except 903... Doug had managed to fry his 33cm
117 transverter before we could catch him from DM78. Oh well, it happens.
121 With the thunderstorms looking persistent, we decided to call it a day around
122 6:30pm local time, and headed back to my place.
126 Sunday, I was itching to operate some from DM79, since we hadn't done it on
127 Saturday and I do, after all, live in DM79pa! My 7-year-old daughter
128 Elizabeth was also very interested in seeing what this was all about.
129 So, we drove up the driveway to the top of
130 the hill by our mailbox, and set up. Since I didn't have antenna turning help,
131 I didn't put the mast up very high.
135 It was really frustrating. The 222 gear was working well, and I logged three
136 contacts, with W0AH, K0RZ, and a new grid with N0IO. However, while I could
137 hear fine on 432, the TX in the 736 went crazy on transmit. In talking with
138 Bill about it on 222, it appears that this is a well-known problem in the
139 Yaesu radios when the supply voltage gets low. Since I did not charge the
140 battery overnight, we assume that's what the problem was. This took out 432
141 entirely, since the other rig was already believed to be toast. We worked
142 hard to get K0RZ on 1296 with no luck at all hearing each other. That seemed
143 really strange until I was pulling the antennas down and discovered that the
144 feed line attachment to the driven element had cracked, and was no longer
145 connected! So, no wonder
146 it didn't work... And, since 1296 was such a total bust, we didn't try 903...
147 It might have worked, it might not have.
151 All in all, Sunday morning's operation was pretty frustrating, but the three
152 contacts did give us two multipliers... one for operating rover from DM79,
153 one for working DM77 which we had not managed on Saturday. So, I won't
158 All in all, not a bad weekend. It would have been nice if more folks were on,
159 and I sure wish our gear had run better. But, we only heard a few
160 folks we couldn't work, and so we can't help but be pretty happy with our
161 effort! Now, to get things fixed/working for September...

181 736 on the bottom for 432, Bdale's Kenwood 790 for 1296 and the IF for
182 903 next up, then John's Icom 735 driving the 222 transverter in the
183 rear, and Bdale's 903 transverter topped by the DEM TIB interface to
184 the 790. John's SWR/Power meter which has a remote sensor is to the
185 right of the Icom, and even though it doesn't cover 222 explicitly, it
186 was reassuring to see the power meter wiggle while we were
187 transmitting! Note the paper logs, not even in Bdale's usual VHF
188 format... with so few folks to talk to, it just didn't matter.

197 were more readable this time than sometimes, but still treat the times as being

298 For 222, we ran John's IC-735 and DEM transverter, and his K1FO yagi.
302 For 70cm, we ran John's Yaesu FT-736, a Mirage amp making about 100 watts,
303 and a Landwehr preamp mounted near my Rutland Arrays K1FO yagi.
307 On 33cm, we ran the TS-790's 2m section through a DEM TIB to a DEMI
308 transverter making about 10 watts into a homebrew Kent Britain-style yagi.
312 On 23cm, we ran the TS-790 making about 10 watts into a homebrew Kent
317 Power was from a 27DC-form-factor deep cycle battery for everything,
318 feedlines were a mix of low-loss RG-8'ish sized cables with mostly N
319 connectors. We logged on paper, and post-processed the logs using the
320 VHF-DX software for Windows.
