To: info-hams@ucsd.edu I recently bought a HTX-100 (no equipment flames please...buying the FT-990 would keep me from continuing school), and have set it up with a "V" type 1/2 wave indoor antenna. I have not been able to talk to anyone from my apartment yet. However, I have had good results (when the band is in) from a measly 1/4 wave mag mount on my car. The building I live in is made of stucco, with (I'm reasonably sure) chicken wire in the walls. Most stucco buildings I've seen have this wire in the walls. I am curious if the wire is acting as an attenuator. If anyone has had a similar experience, let me know. Yes, it is possible for me to put the antenna outside. However, rather than having people lining up at my door complaining of TVI, I wanted to keep everything indoors. Thanks! Louis -- Louis A.

One C-class flare was observed: a C3 at 2220Z which was not observed optically. The remainder of the period was marked by very low levels of activity. New Region 7696 (S18E05) was assigned today. X-ray imagery indicates that a new region is rotating onto the disk near N18E87. Solar activity forecast: solar activity is expected to be very low to low. The geomagnetic field was predominantly quiet to unsettled. A brief active period was observed at mid-latitudes from 0000-0300Z. Active to storm level conditions were observed sporadically at high latitudes from 0900-1800Z. Geophysical activity forecast: the geomagnetic field is expected to be generally unsettled for the next three days.

Otherwise, near-normal conditions should continue. COPIES OF JOINT USAF/NOAA SESC SOLAR GEOPHYSICAL REPORTS ======================================================== REGIONS WITH SUNSPOTS.

The base is nearby. Now, a cellular phone involves many 'cell sites' which consist of transceivers/antennae on towers which cover a limited radius. When the cell phone is in the vicinity of one of these sites, the signal of it passes through. When the phone is out of range from one site and enters the range of another site, the signal is passed onto that new site. Both types of phones have transmit/receive frequencies. Cordless phones (most common in homes) operate in the 46-47 Mhz range. Newer ones with voice scrambling operate in the range of 900 Mhz. One range of frequencies are typically used for handset->base, so you can only hear the voice of the person holding the phone. The other frequency, base-> handset, is where you can hear both sides. Also, since there are no 'cell sites' for cordless phones, you can usually listen to a conversation in full, uninterrupted. Cellular phones operate in the 800 Mhz range (about 870 - 896 Mhz). Since cellular phones jump from cell to cell, you can almost never keep up with a full conversation - mainly because you would have to track down which cell site the person jumped to. Hope this helps clear up some of the confusion.

These things used to be popular in the beginning days of 2 Meter FM; there was an article published somewhere called the "sonobaby" that showed how to convert one to the 2 M FM ham band. The one I had had a saltwater activated battery that put out something like 15 VDC and transmitted somewhere around 150 Mhz FM. There was no effort made by the designer to miniaturize the circuitry, and it ran something like 1 watt. There was also a timer circuit that melted a fuseplug that sent the thing to the bottom after X hours of transmitting. The body of the sonobuoy had about 100 feet of what looked like miniature twinlead connecting the hydrophone to the FM transmitter. I doubt seriously if the sonobuoy is worth anything other than a cur- iosity point. > issues, illegal transmission issues, etc...) that we should be You can always take it apart, put in a ham band crystal and retune it.

To: info-hams@ucsd.edu Greetings, I have a non internet friend who is visiting the U.S.A. and Canada in early April this year. His name is Kerr and his callsign is ZL2QD. He is mainly a HF operator, but has recently purchased a VHF/UHF HT. The HT has full 2m (144-148) and 70cm (430-450) coverage. He has applied to the FCC for a permit to operate in the U.S.A. but that was only 30 days ago. We are informed the FCC takes 60 days to process reciprocal permits. He has asked the FCC to forward his licence to Skagway, Alaska. His itinerary from Skagway will be Whitehorse-Vancouver- Calgary-Vancouver and San Francisco. To cater for contingencies, I have the following questions: 1. Can Kerr operate in Canada with a US licence? 2. If the FCC does not come up with the goods, can he get a Canadian licence by presenting his New Zealand licence to the appropriate Canadian authorities. If so, where are the licensing offices in the Canadian cities mentioned above? 3. If he were to obtain a Canadian licence, what is its validity in the U.S.A.? 4. Could some kind individual email me the freqs for 2m and 70cm open repeaters in the cities mentioned above. I read rec.radio.amateur.misc every day so usenet postings will be ok.

Hell, if you're going to sell the car privately, go get a cell phone ($149 reconditioned all over the place) and install it! Of course, if you're driving what most hams are driving, the torn upholstery, dents in the fenders, faded paint, and cigarette ashes and coffee stains everywhere are going to make much more of an impact than one hole in the roof. Adding the cell phone might well double the value of the car. - Brian ------------------------------ End of Info-Hams Digest V94 #335 ****************************** ******************************
