- Suggest that you post in alt.radio.scanner and rec.radio.scanner
-
- GRE America makes two such boxes; one for handheld and one for
- desktop scanners. They don't double the coverage range but downconvert
- 810-950 to 410-550. You can call them at 415-591-1400 or
- 800-233-5973.
-
- Frankly, I'd just buy a new scanner having 800 MHz capability. There
- are newer devices having much better performance than the old BC
- scanners. Again, look on the two scanner newsgroups and you'll get an
- avalanche of recommendations.

-
- I don't have regular access to special equipment but one day when I had
- a few spare moments, I spec'd out my Alinco DJ560-T dual band transceiver's
- sensitivity over various frequencies. I used a Marconi 2022D signal
- Generator which outputs from 10KHz to 1GHz and a few feet of an
- extremely low loss Andrew cable. All readings were taken when a solid
- "FULL" reading was achieved on the LCD bargraph.

- SYNOPSIS OF ACTIVITY
- --------------------
-
- Solar activity was very low. Minor B-class flares were
- observed from the three spotted regions on the disk. Region
- 7620 (N05E03) continued slow growth. Region 7618 (N06W71)
- continued its slow decline. A small filament located near
- N11E55 faded between 23/1557-1702Z.
-
- Solar activity forecast: solar activity is forecast to be
- low. Infrequent C-class flares are expected from Regions 7618,
- 7620, and 7622 (N14E48).
-
- The geomagnetic field remained quiet. The forecast coronal
- hole disturbance did not appear on schedule.
-
- Geophysical activity forecast: the geomagnetic field
- should become unsettled to slightly active on 24 Nov in
- response to the end of the coronal hole stream. The field
- should then become quiet to slightly unsettled for the
- remainder of the period.
-
- Event probabilities 24 nov-26 nov
-
- Class M 20/20/15
- Class X 05/05/01
- Proton 05/05/01
- PCAF Green
-
- Geomagnetic activity probabilities 24 nov-26 nov
-
- A. Middle Latitudes
- Active 25/20/15
- Minor Storm 15/10/05
- Major-Severe Storm 05/01/01
-
- B. High Latitudes
- Active 35/25/20
- Minor Storm 15/10/05
- Major-Severe Storm 05/01/01
-
- HF propagation conditions continued normal over all
- regions. The anticipated coronal-hole-related disturbance did
- not materialize on 23 November as expected. Yohkoh x-ray
- imagery shows that the equatorward boundary of the hole has
- retreated northward and hence should be less geoeffective than
- it has been on previous rotations. If this is the case,
- conditions may become only mildly degraded over the high and
- polar latitude paths on 24 November. There is a chance this
- disturbance may not materialize at all, which would result in
- generally near-normal propagation through at least 26 November
- inclusive.

- All times are in Universal Time (UT). Characters preceding begin, max,
- and end times are defined as: B = Before, U = Uncertain, A = After.
- All times associated with x-ray flares (ex. flares which produce
- associated x-ray bursts) refer to the begin, max, and end times of the
- x-rays. Flares which are not associated with x-ray signatures use the
- optical observations to determine the begin, max, and end times.
-
- Acronyms used to identify sweeps and optical phenomena include:
-
- II = Type II Sweep Frequency Event
- III = Type III Sweep
- IV = Type IV Sweep
- V = Type V Sweep
- Continuum = Continuum Radio Event
- Loop = Loop Prominence System,
- Spray = Limb Spray,
- Surge = Bright Limb Surge,
- EPL = Eruptive Prominence on the Limb.

- RE: PACKET RADIO TNC INFORMATION.
- ATTN: ALL HAMS INTO PACKET RADIO COMMUNICATIONS
-
- I am employed by the Fayette County, PA Emergency Management Agency
- in charge of the computer equipment. My boss recently asked about the
- possibility of using packet radio over our radio channels. (Commercial
- Public-Safety channels).
-
- Here is the problem. We will be upgrading Communication equipment
- to a Motorola Smartnet 800MHZ Trunked System. Does anyone have
- any information concerning the interface of a packet node controller
- to a trunked two way radio (Motorola Maxtrac 800).
- Due to the design of trunked systems, *INSTANT* transmit of a field
- unit thru the repeaters is not possible. Also if the trunked system
- gives you a busy channel status, the packet controller needs to know.
-
- I appreciate any help that you can give.
- Please E-Mail, Post in this group, FAX or write.

- Subject: Some TH-78A power tips
- To: info-hams@ucsd.edu
-
- Some people have complained about the battery life on the TH-78A. I
- came up with these tips by checking out the power consumption under
- various configurations. In the case of power-saver mode, figuring out
- the average current with my DVM was impossible, so I ran the radio on a
- large capacitor and timed how long it took to die. These tips won't
- solve everything, but they might help.
-
- o The rig draws close to 2ma even with the power turned off, so don't
- leave the rig off with the battery installed for several days and
- expect full capacity to be maintained.
-
- o If you're only using one of the bands, shut down the other to extend
- your battery's life -- current consumption with the squelch closed
- is cut by almost a third.
-
- o If you're monitoring two frequencies on the same band, use the f2
- button to receive both simultaneously rather than scanning between
- them -- the battery saver with two receivers will use about half
- the current of one receiver that is scanning.
-
- o You can make up a battery pack by putting nickel metal hydride AA
- cells in a BT-8 battery holder. A small strip of aluminum from the
- positive battery terminal to the depression in the top of the case
- will allow you to recharge the pack inside the rig. This will give
- you 1000mah capacity without enlarging the size of the radio, and
- NiMH cells have no memory effect. (But they *are* expensive.)

- I spent alot, but they sent one to my wife who doesn't spend hardly anything.
- I assumed that it is a way to bring in those that wouldn't normally go there.
- (The rest of us go without being prodded.)

- With the current callsign structure it can be difficult to know when you're
- calling a novice/tech+. I've got a 1 x 3 callsign, just like a tech+, but
- have had an Extra ticket for 25 years. As a result, when I operate in the
- novice bands, I tend to answer CQ's from people sending 10 wpm or less,
- just to avoid the problem of two higher-class licensees cluttering the
- limited space available to the novice/techs. Problem is, this
- discriminates against those novice/techs looking for a higher speed QSO.
- Dare I run the risk of being rude, Gary, and answer an N-XXX call sending
- CQ at 20 wpm? :-) Seriously, we all ought to drop by the novice bands to
- chat (with _them_, of course), and not isolate them.

- Subject : Re: CONELRAD-what was it?
-
- We have a unique situation here on Oahu: All AM and FM stations are linked
- to the county CD EOC (basement floor of the municipal building). During any
- county or statewide emergency, broadcasts made from the EOC are heard on
- ALL stations - as you tune across the dial you hear only our EOC announcer.
- During our monthly outdoor warning siren test (first working day of the
- month at 1145 all 150 sirens island-wide are activated; state-wide too
- but I don't know the total number of sirens in the entire state - guessing
- at 400) (oh, we have a WWV receiver so we make sure the sirens start at
- exactly 11:45:00 - they're tone-activated on around 156 MHz) our EOC
- describes to the listening audience on all the bcst stations that we're
- conducting the monthly test of our communications and siren equipment.
- THEN we get a flood of phone calls:
- ``The siren in our neighborhood didn't work''
- ``Hey, why did you guys sound the sirens?''
- ``Why did you interrupt my favorite song?''
- ``I heard you on every station - how'd you do that''
- ``Can't you turn the volume of the sirens down?'' (120 dB)
- Most of our sirens are the Thunderbolt air-compressor rotating model made
- by Federal Signal Corporation, but we've got a few of the newer all-electronic
- sirens (rotating) (they sound `funny'); they're also made by Federal.
-
- So, we really don't have a primary/secondary station concept here. I guess
- you could say that every station is primary. A couple stations received
- money from the feds for new generators since we are prone to island-wide
- blackouts sometimes lasting more than 24 hours. Out of the 2 dozens
- or so stations at least two have the capability of staying on the air
- more than 48 hours.
-
- Oh, we get a real emergency at least once each year; usually either a
- hurricane or tsunami (tidal wave) warning.
