- A friend of mine and I did just this back in 1980. We built a system
- around a standard 10 speed bicycle frame with a 20" wheel. We used a
- alternator out of an old GM car and 2 12 volt batteries in parallel.
- We were both in shape (we were active duty military at the time) and
- figured that we could take turns on the pedals.
-
- One problem that we had was that he was over 6' tall and I'm only 5'6"
- with short legs and we had to make the seat quickly adjustable. The
- best way to do it is to use a low power rig (about 100 watts) with
- very few gadgets. We tested the system out and found that if we kept
- the actual transmit time down (or used CW) we could keep the batteries
- charged reasonably well. The modifiers were going to be great.
-
- Our antenna was a multi-band dipole made out of 300 ohm TV antenna
- wire. It was actually 4 dipoles in parallel. We stretched out two
- pieces of 300 ohm to 40 meter half-wave length and then cut one of the
- conductors on each side at 20 meter length. We did the same with the
- 15 and 10 meter sections. We tied them all together in parallel and
- fed it with 75 ohm coax. The antenna was raised by using several
- sections of TV antenna mast (the kind that is tapered at on end) guyed
- by the antenna from 2 directions and nylon rope from the other 2
- directions.
-
- Then the military decided that we were going to take a nice vacation
- in Sunny Saudi Arabia for a couple of months and we missed field day
- :-(. Deployments mess up the best laid plans. As it turned out, my
- friend got transferred to Keflavik, Iceland and I ended my hitch
- before the next field day so we never got to actually run it.
-
- Two things to note: you will need batteries because nobody can pedal
- indefinately, and you want to be in good shape before you do this.
- Good Luck.

- Well, yeah, I can see where it's discouraging, but it ain't all that
- bad.

- Consider that the first earthquake, or whatever you get in Kentucky, may

- Somebody recently compared ham frequencies (among commercial ones) as

- John, if checking the local ham swapfests and swap lists fails, then consider
- making them yourself.
-
- Look up the formula for capacitors in the ARRL handbook. You can use
- small sections of sheet copper, single sided printed circuit board, or
- even lids from tin cans for the plates. Use window glass to insulate
- the plates...with the glass extending out from the plates to assure the
- 6Kv won't arc around the plates. You'll find the dielectric constant for
- glass to be very good and normal thickness of window glass should give
- adequate Kv ratings.
-
- Another source for factory make caps in this range can be old television
- receivers...
-
- Try stacking six 1.5 KV rated disc ceramic caps in series with good
- spacing between them. Let's see, six 30pf in series should give about
- 5 pf that you asked for...
-
- Best Luck

-
- WARNINGS ISSUED:
-
- - POTENTIAL LOW LATITUDE AURORAL ACTIVITY WARNING
- - POTENTIAL MAJOR TO SEVERE GEOMAGNETIC STORM WARNING
- - POTENTIAL SATELLITE ANOMALY WARNING
- - POTENTIAL ELECTRICAL GEOMAGNETIC INDUCTION WARNING
- - POTENTIAL MAJOR SOLAR FLARE WARNING (PROTON)
-
- ALERTS IN PROGRESS:
-
- - MAJOR PROTON FLARE ALERT
- - SATELLITE PROTON EVENT ALERT (2,500 PFU PROTONS IN PROGRESS AT > 10 MEV)
- - POLAR CAP ABSORPTION ALERT (RIOMETER MEASUREMENTS > 5.0 DB DEVIATION).
- - POLAR RADIO BLACKOUT ALERT (IN PROGRESS)
-
-
- ATTENTION:
-
- A MAJOR middle latitude geomagnetic storm is expected to begin on 24
- March. Periods of severe geomagnetic storming is possible over middle
- latitudes, while high latitudes should experience frequent severe storm
- periods (K indices of 8 and 9). The cause of this predicted activity is
- the major proton flare of 22 March (class X9.4/3B proton flare at 22:47 UT).
- A high risk exists for major storming.
-
- Satellite level protons reached event thresholds of 10 p.f.u. at 08:20
- UT on 23 March and skyrocketed from there to moderately high levels of
- 2,500 p.f.u. thereafter. Some satellite anomalies are possible with proton
- levels at this intensity.
-
- A PCA event with an accompanying polar radio blackout began at 09:31
- UT on 23 March and is expected to continue for the next 24 to possibly 48
- hours. Riometer measurements indicate an absorption intensity of greater
- than 5.0 dB's. A Forbush decrease is expected with the magnetic storm.
-
- An interplanetary shockwave is expected to impact and produce a
- magnetic SSC sometime between approximately 09:00 UT and 18:00 UT on 24
- March. Minor storm level fluctuations are expected to begin shortly
- thereafter, increasing to major storm levels by the end of the UT day on 24
- March. Significant storming is possible. The flare which is producing
- this event was significantly more powerful and radio-rich than the flare
- which produced the previous storm warning a few weeks ago. The probability
- for magnetic storming from this event is much higher than the last warning,
- due primarily to the sensitive position of the flare on the sun.
-
- Geomagnetic induction will be possible if this storm materializes as
- expected. Significant magnetic perturbations are forecasted for all
- latitudes. Higher latitudes (middle northern and high latitudes) will
- likely experience the most intense storming. Although it is difficult to
- predict actual expected magnetic activity levels, we are predicting a
- middle latitude magnetic A-index of 40 for 24 Mar, and 50 or greater for 25
- March. There is a good possibility middle latitude A-indices could surpass
- 75 on 25 March. Magnetic K-indices for middle latitudes are predicted to
- reach levels of 6 and 7 (a level of 9 is the top of the scale). High
- latitudes will probably see values of 8 and 9.
-
- A LOW LATITUDE AURORAL ACTIVITY WARNING has been issued. Auroral
- activity will be high to very high over high latitudes, and high over
- middle latitudes. Significant southward migration of the auroral zone is
- possible with this event. Low latitude auroral activity is a real
- possibility. If storm intensities surpass levels expected, auroral
- activity could possibly be seen as far south as Florida.
-
- Significant HF disruptions are possible (if not likely) over all
- latitudes. Polar regions are already experiencing blackout conditions due
- to the proton event. High absorption could produce near blackout
- conditions on many middle latitude paths. Strong fading and distortion is
- expected for low and middle latitudes.
-
- There is a high probability for significant VHF bistatic auroral
- backscatter communications on 24 and 25 March. Low latitude auroral
- backscatter communications is also expected to be possible over many areas.
- Middle latitudes will experience the best opportunities for auroral
- backscatter communications.
-
- The most intense terrestrial activity is expected to last between 12
- and 24 hours, with active to very active geomagnetic post-storm activity
- persisting until 26 March (barring any further major solar flaring).
-
- PLEASE SEND ANY REPORTS OF AURORAL ACTIVITY, AURORAL BACKSCATTER
- COMMUNICATIONS OR SIGNIFICANT HF RADIO DEGRADATION TO: OLER@HG.ULETH.CA
- PLEASE INCLUDE THE LOCAL AND UT TIME OF OBSERVATION, GEOGRAPHICAL LOCATION
- (LATITUDE/LONGITUDE) AND A BRIEF DESCRIPTION OF THE PHENOMENA OBSERVED.

- Flare Event Summary
- ** HIGH TERRESTRIAL IMPACT IS POSSIBLE **
-
-
- --------
-
-
-
- MAJOR ENERGETIC EVENT SUMMARY
-
- A large major X-class flare ripped out of Region 6555 late today. The
- event began at 22:42 UT, peaked at 22:47 UT and ended at 23:10 UT on 22
- March. The flare attained an intense class X9.4/3B rating and was located
- at a S26E28. Radio emissions were very strong in the 245 MHz and 10 cm bands.
- The 245 MHz emission hit 260,000 s.f.u.. The 10 cm burst peaked at 36,000
- s.f.u.. Moderate intensity Type II and IV sweeps were observed with this
- event. The integrated x-ray flux was fairly high, rated at 0.560 Joules per
- meter^2. A moderate intensity proton event is expected anytime now. A proton
- enhancement has been observed over the past hour. Solar protons are expected
- to peak at levels near 80 p.f.u.. A Polar Cap Absorption (PCA) event is
- expected to begin at anytime. A TOTAL POLAR RADIO SIGNAL BLACKOUT IS EXPECTED
- ANYTIME. The duration of the blackout is expected to be approximately 24 hours.
-
-
-
- POTENTIAL TERRESTRIAL IMPACT ASSESSMENT
-
- Further consultation and analysis will be required before an official
- terrestrial impact will be released. This terrestrial impact forecast will
- be issued after 17:00 UT on 23 March.
-
- Preliminary results suggest that a high probability exists for a MAJOR
- middle-latitude geomagnetic storm, beginning sometime on 24 March. A more
- specific time period will be given with the 24 March bulletin (or warning).
- This major flare was significant and has the potential of producing large
- terrestrial impacts. More detailed information regarding the predicted state
- of the geomagnetic field will be given later today.
-
- Region 6555 has been magnetically analyzed in greater detail now.
- This region sports a beta-gamma-delta magnetic configuration. The internal
- structure is associated with strong fields, high gradients and high shear.
- The spots are contorted in an unstable configuration which will most likely
- produce further major flaring.
-
- A POTENTIAL PROTON FLARE WARNING HAS BEEN ISSUED, AS HAS A PROTON
- FLARE ALERT associated with this latest major event. A POLAR RADIO
- BLACKOUT WARNING IS IN PROGRESS. A POTENTIAL PCA ACTIVITY WARNING IS IN
- PROGRESS. The POTENTIAL SATELLITE PROTON EVENT WARNING CONTINUES.
-
- A magnetic storm warning will likely be issued later this UT day.
-
-
- ** End of Alert **

-
- Hi. I have an old Realistic "Navaho" 23 channel CB rig that I'd like to
- modify for use on 10 meters. It has a "delta tune" knob with +, centered,
- and - positions; this is NOT a sideband control, is it? In the absence of
- sideband, I'd like to use the rig for CW work; I think I can do this by
- replacing the mike with a key in an appropriate way, since there would
- then be no amplitude modulation (maybe I need to apply a small voltage to
- the key as well, to get a nonzero amplitude).
-
- This unit is all crystals, but I don't see any crystals that are cut for
- the CB frequencies. Some look like first subharmonics (14.95 MHz, 14.96,
- etc.), while some are at other frequencies (23.39 MHz, 22.34, etc.).
- What's going on here? How to I go about moving this units channels into
- the 10 meter CW band? Any help will be greatly appreciated.
-
- Thanks,

- PROPAGATION FORECAST BULLETIN 10 ARLP010
- FROM TAD COOK, KT7H, SEATTLE, WA
- MARCH 23, 1991
- RELAYED BY KB8NW/OBS & BARF-80 BBS
- TO ALL RADIO AMATEURS
-
- During the past week we saw more unstable conditions with continuing
- solar flare activity. The solar flux rose to 276 on March 18, which
- was the highest level so far this month. Propagation was mostly
- good with partial radio blackouts on occasion due to solar flares.
- Several times the K index rose to 4, indicating unstable geomagnetic
- conditions.
-
- During the forecast week we should see a tapering off of the solar
- flux from the 250 level down to around 210. There are a couple of
- active regions on the Sun that are capable of at least moderate
- activity, and perhaps some major flares as well. Check the K index
- on WWV at 18 minutes after the hour. It is updated every 3 hours
- starting with the posting of the new day's solar flux at 1818 UTC.
- If the K index is less than three, shortwave propagation should be
- quite good. K indices of three and rising indicate disturbed
- conditions, especially on polar paths.
-
- The northern hemisphere is moving into Spring which normally means
- better propagation with longer worldwide openings. Barring any big
- flare activity, we can expect generally better conditions with the
- change of season.
-
- American sunspot numbers for March 7 through 13 were 123, 126, 113,
- 132, 144, 158 and 141 respectively, with a mean figure of 133.9.
- For the week of March 14 through 20, they were 148, 163, 183, 166,
- 162, 157 and 155, with a mean of 162.

- You are right. There isn't any. The usual way this is done is to
- wire something up to the squelch relay output ( recorder control ).
- It might be possible on some applications to use the audio out
- with appropriate circuitry but I agree the lack of ability to
- request squelch status is unfortunate.
