- I'm considering the Cushcraft A3S tri-bander, along with the 40-mtr add on
- kit. Does anyone have positive/negative feedback on the 40-mtr kit? Does
- it affect the bandwidth of the other 3 bands? Does it deliver the equivalent

- I recently got active again after being off the air for a few years.
- I have been looking around at the ham-related software that is available
- and it seems to be pretty minimal, especially Windows based software.
- I just got the QRZ! CD-ROM yesterday which includes most of the archives
- and I didn't find a lot of interest, at least to me, on there.
-
- I am currently developing a Windows-based Graphical User Interface for
- TNC 2 compatibles that I plan to make available as shareware. It will
- be a lot more than just another terminal program. It will provide menu
- and forms access to all the TNC parameters and settings as well as menu
- driven interfaces for accessing popular BBS, Mail Systems and Network Nodes.
- For all those like me who can't remember all those #&*$#@ commands.
-
- I would be interested to know how many hams are using Windows on the PC
- in their ham-shack and do you use it to control your TNC? Also, do you
- have any suggestions for ham software you would like to see for Windows?
-

-
- My understanding is that the card reader/plate generates a small AC field
- which is sufficient to power the card and have it radiate its serial number
- back to the plate. I don't have any clue on frequencies, data formats,
- or whatnot.
-
- It is doubtful that such technology is used to track employee movements.
- Since the field drops off at the inverse of the distance squared, you
- would probably need a field powered n^4 to make your card work. In addition,
- the sensor net would probably be cost prohibitive. Last I heard, these
- systems run a few thousand dollars for 4 or 8 card plates. Imagine if
- you wanted thousands of detectors.
-
- BTW, I used to keep the card in my wallet, but now I pull it out when I use
- it. I found that the magnetic stripes on my credit cards becoming less and
- less reliable. I am of the opinion that these cards, when activated,
- do slowly affect the credit cards.

-
- Ahh! Naive amateur! You found me! After reading the fantastic
- claims from Ramsey and seeing a positive review in 73 Amateur Radio
- Today, I plunked down my $'s and got a FX 146 kit. I got the thing
- to work and even programmed two old EPROMs so I could dial in the
- frequency from the front panel via BCD thumb switches. I had fun
- putting this thing together and learned a bit in the process. The
- performance is, as I've been reading all over, disappointing. The
- only way I could get this thing to preform half way decently was to
- put a small two cavity filter in the antenna feed line. The
- cavities are twice the size of the radio!
-
- Ok, I have this FX 146 and now I would like to fix whatever needs
- fixing to make it a decent radio. Mainly improve the front end as
- Dana has suggested above. (And unload the cavities!) The problem
- is that when it comes to RF, I'm a kit builder at this point. I
- don't have easy access to spectrum analyzers, 200MHz signal
- generators, etc. I do have a 100MHz scope, DIP meter, 600MHz
- counter and a VTVM with RF probe though.
-
- How do I couple the 50 ohm antenna input to a decent filter to an
- amp to another filter to the receiver? I've looked in the ARRL
- Handbook on the subject, but it gets too intense too fast and I'm
- lost after the second paragraph. Would a diode DBM mixer really be
- that easy to implement? If so, how? How about cutting up a tin
- can and soldering up a shield around the VCO? What is loop
- division any how? (=VCO freq./ REF Freq.?) How about cleaning up
- the RF output. Is there some way to do this simply without a
- spectrum analyzer? How.
-
- Has anyone done any of what Dana suggests? I am seeing a lot of
- complaining but no solutions. I'd sure love to improve my FX 146
- and I'll bet there are several other FX builders who would do the
- same! I'm not going to chalk this up to a lesson learned and run
- out to buy some old Icom, Kenwood, Yeasu, etc. I bought this kit
- to learn about RF electronics.

- Control channel frequencies are typically PL protected and use a set of

- THIS is a big issue. There needs to be 10 or 15 SIMPLEX VOICE channels
- defined, and they need to be defined nationwide. A SEPARATE set of TEST
- and experimental frequencies is also needed to provide a place for
- people to play with their crossband repeating radios without interfering

- Remeber also that the repeater directory is out of date a few months
- before it gets published. For the most part this is not a big problem,
- but in the case of trying to find empty frequencies, it is not a good

-
- This is a trap most coordinating groups fall into. The big demand is from the
- repeater owners, not the simplex users. They are responding to their members,
- good or bad. I don't know what the answer is except to encourage more input

- I couldn't agree more. One of the things the Texas VHF-FM Society has done
- is to tell the ARRL repeater directory editors that band plans should be
- published for EVERY STATE, not just what the ARRL thinks their "national"
- band plan is. Don't know if they'll do it, but...
