-
- I live on the west coast near San Francisco (Menlo Park) and wondered if
- any netters have had any luck receiving news broadcasts from All India Radio. I
- have a basic SONY 7600A receiver with analog tuning.
-
- Tuning/Antenna/Time info would be much appreciated.
-
- Please e-mail suggestions to me.
-
- Thanks,
- Sanjay

-
- Some one, in reply to a request for comments on ham radio construction
- projects, discussed the difficulties in realizing crystal filters.
-
- This brings up an important philosophical point: just how much of the
- equipment do you have to design and fabricate to qualify for "home made".
- I, for one, don't think that it makes much sense to build even major
- components which are common off-the-shelf items. These include:
- transistors
- integrated circuits
- loudspeakers
- IF crystal filters
- frequency control crystals
- "block" VHF power amplifiers (Motorola and Japanese)
- microwave integrated circuits
- in most cases, diode ring mixers (Minicircuits and others)
- etc.
- My goal would be to get a working rig with modest effort. In any case, building
- a "real" rig is a substantial undertaking. OK, go back and replace some of the
- off-the-shelf components with those of your own design at a later date - but
- stick as much as possible to system design, not component design, if you want a
- useable product in a finite time.
-
- Hats off to those who can do ALL the detailed parts and finish in a reasonable
- time.

- However reasonable your interpretation, it really doesn't matter. What
- matters is how the case would be presented to a jury of "your peers*"
- in a court of law where you would be prosecuted.
-
- Think about it in that light and you may want to change your interpretation.

-
- I saw an article in one of the magazines (QST Hints & kinks??) about
- a year ago that did just that. It seems that it only takes the
- swapping of 2 wires inside to reverse the power and squelch controls.
- If you look at the schematics, it should be easy to see. It seems
- that nearly everyone who owns a '140 thinks about that within a week.
- I am very nearly breaking down to the point of buying a TS-680S to
- pick up on 6m. In 22 years of ham radio, I have never worked the
- 6m band.....with my luck I'll finally get the money for it at the
- end of the sun-spot cycle......Murphy lives in my back pocket.
-
- I have heard quite a few TS140 and TS-440 rigs on the air. They
- sound great!! I never hear any complaints about them, just real
- nice signals. Have fun, don't drown...

- Message-ID: <29490001@hprmokg.HP.COM>
-
- I use my scanner in the kitchen to monitor the 2 meter repeaters.
-
- When I hear a friend on, I turn on the rig and give 'em a call.
-
- 90% of the hours on my scanner are amateur radio-related. 73 Magazine
- is going to have an article on scanners in a future issue, I hear,
- that will feature two modifications: 1.) how to use the scanner to
- measure FM deviation and 2.) how to use it to decode PL frequencies.

-
- The two knobber is probably an L network which can, in addition to
- resonating the antenna, transform a high-impedence to a low (or visa-versa
- if you reverse the connections). The three knobber is probably a pi which
- can resonate as well as perform impedence transformations in both directions
- without requiring re-cabling or internal switching.
-
- A "true" long wire (>= 1 wavelength) will have an impedence > 50 ohms and
- as such an appropriately connected L will suffice. The three knobber you
- refer to probably has those extra "inputs" with connectors, switch positions,
- etc as part of function packing to raise the price point up a bit.
