8 spectrum</a>.</strong> In 1998, ARRL petitioned the
9 FCC to liberalize the code sequences and include automatic power
10 control for powers above 1 watt. This petition may prove to be
11 controversial, as TAPR and other groups want to lower the SS
12 operating frequencies below 420 MHz--some as low as HF--yet
13 others feel SS should be banned. Bob Buaas and his group on the West
14 Coast continue to with their STA, which allows SS at 50 MHz and
15 higher. AMRAD members could join the STA and put some systems
18 <li><strong>Interference testing Part 15 SS devices.</strong> At a
19 TAPR meeting, there was some concern expressed about the
20 compatibility of Part 15 devices with Amateur Radio systems,
21 particularly at, but not limited to, 2390-2400 MHz. Part 15
22 proponents, on the other hand, are apprehensive about sharing the
23 band with amateurs. In this band and in 2401-2417 MHz, amateurs
24 are primary and Part 15 users can use the bands on a non-
25 interference basis. Nevertheless, it may be possible to
26 demonstrate that there is no problem or find ways of mitigating
27 any interference through a test program. I have been in contact
28 with Jim Lovette of Apple to run some tests and we talked about
29 the desirability of test groups on both the East and West
30 Coasts. There is willingness on both sides but nothing specific
31 has been done to date.</li>
33 <li><strong>Higher speed digital systems.</strong> This is one of
34 Terry's favorite saws. Where are the high speed packet modems and
35 radios? Dave Sumner questions why US hams are not doing more with
36 higher speeds; he cites S53MV's article in CQ ZRS on his 1.2288
37 Mbit/s 13-cm system.</li>
39 <li><strong>Utilization of <a
40 href="http://www.amrad.org/projects/microwave/">microwave
41 bands</a>.</strong> Because of
42 line-of-sight propagation in these bands, their popularization
43 requires an infrastructure or backbone. Otherwise, microwave and
44 millimetric frequencies will be used only for isolated short-range
45 links. There was a remark that AMRAD may not be in a good
46 position to develop microwaves. That may be true and there are
47 several microwave clubs that may be better able to do
48 it. Nevertheless, there may be a role for AMRAD. We could lose
49 these bands unless we come up with 24-hour uses over wide
50 geographic areas occupying large portions of the bandwidth
53 <li><strong>Multimedia systems</strong>, possibly a repeater in the
54 Washington area. At a recent PVRC meeting, I was talking with a
55 PVRC member who was pushing this concept. Sandy points out that
56 Metrovision has done mixed media for years. Nonetheless, theirs is
57 an analog system; some work could be done on a digital multimedia
58 system, possibly in cooperation with Metrovision.</li>
60 <li><strong>Developing an amateur beacon system capable of
61 contributing propagation data to the ITU.</strong> Amateurs have
62 an extensive array of beacons from HF through
63 microwaves. Unfortunately,their transmissions are received only on
64 a real-time basis and there is no attempt to automatically
65 receive, reduce and report the data to any scientific group such
66 as ITU-R Study Group 3 or URSI. IARU President Dick Baldwin has
67 recently reinstructed the IARU beacon working group to reorient
68 the beacon network into one that includes automatic reception and
69 reporting. The ITU has a transmit format that permits machine
70 reception. AMRAD could study that and recommend its adoption by
71 amateur beacons or come up with one that might be more suitable
72 for amateur use. We could also design any hardware and software
73 hams would need. Dick Barth showed interest in this project and
74 has asked me to supply him with the ITU documents so he can
75 prepare an article on the subject.</li>
77 <li><strong>Amateur systems for worldwide noise-measuring
78 campaign.</strong> ITU-R Study Group 1 wants to establish a
79 worldwide network for collecting noise level measurements. The
80 contention is that noise levels are rising (and limiting the use
81 of radio) but no one has definitive data. Hams could participate
82 in one way or another if someone like AMRAD figures out how.</li>
84 <li><strong>Participate in Mars Global Surveyor Relay
85 Experiment.</strong> See January 1996 QST, page 45 for an outline
88 <li><strong>Designing <a
89 href="http://www.amrad.org/projects/dsp/">DSP/software
90 radios</a>.</strong> The time is right
91 to do this. There are several guys at COMSAT Labs who are
92 interested in this project and should be willing to cooperate with
95 <li><strong>Application of wireless chip sets to amateur
96 systems.</strong> There are three generations of chip sets (5, 3
97 and now 1-volt) developed for cellular and other so-called
98 wireless applications. It could be a worthwhile project to gather
99 the specs, study them and decide how we could apply them to
100 Amateur Radio designs.</li>
102 <li><strong>Experimenting with digital voice</strong> such as APCO
103 Project 25. TIA did a lot of work picking the most effective
104 digital voice technique for new public safety radios. The one they
105 selected may or may not be best for Amateur Radio. The FCC rules
106 already permit digital voice, even on the HF bands. </li>
108 <li><strong>Develop very small <a
109 href="http://www.amrad.org/projects/space/">satellites</a>.</strong>
110 Mark Kanawati has ideas along these lines.</li>
112 <li><strong>Experiment with automatic link establishment
113 (ALE).</strong> There is now a Federal Standard. QST and QEX have
114 carried articles on this subject. We could either push for
115 adoption of this standard or develop our own.</li>
117 <li><strong>Develop path simulation software.</strong> This was only
118 for the deep pockets in years past but DSP and fast PCs make it
119 possible for hams to do path simulation. At the 1995 ARRL Digital
120 Communications Conference, there was a talk on what has been done
121 to date. We might want to get involved.</li>
123 <li><strong>Design some tech toys.</strong> This could be a project
124 having no other goal than having fun.</li>
