They encourage you to keep taking progressively higher elements until you fail, since there is only one charge per test session. As a result, many people go further than they planned. (It has the side effect of giving the club a higher failure rate!) Taking the code test at the higher speed first, helps overcome nervousness, since you have no pressure to pass. As far as getting people to slow down, the first step is for YOU to send slower! Even then, you may have a tendency to send faster than you can copy, so give yourself a safety margin. I suggest you give the guy who ran out on you, the benefit of the doubt. But, be aware there are all kinds of people out there, and don't let it bother you. As you can guess, you get better with practice. Nothing beats on-the-air experience to build up code speed. A 130' dipole sounds like 80 meters, which may be a good band to get to know people nearby. I find 80 and 40 more friendly than the "Hello Goodbye DX" bands! 73, Fred, K4DII (Mobile CW?

From: bob.stanton@exchange.com Subj: How to Learn CW??? I give up! I have been trying to learn the code since before I was licensed with no luck. I have tried tapes... all I do is memorize the tape... not the code. I sit in front on my computer pounding my head on the keyboard (figuratively). I HATE CW!!! I don't even recognize my own call in CW. I will use it ONLY to upgrade. I have no intention ever to participate in a CW QSO. I realize that there is no way, for the time being, to up grade without submitting to the dictates of those who say "I had to do it so you must". That will change in a few years, but I can't wait till then. I realize that I do not have the proper attitude to learn code. I feel it is the same as when I was a kid growing up in the early 60's. I had to learn Latin so I could participate in the Mass. I took all summer of my school vacation after the fourth grade to learn all the proper phrases and what they meant. The next month the announcement came out that the Mass would be in English. I don't remember any Latin now. What is the best way to do it? I want the HF privileges. I am willing to work for them. I just hit a wall every time I try to force myself to do something I hate. I know that some who read this will just flame me. I have faith that some will have good advice and will be willing to share it with me. Thanks in advance.

It should run with MS-Windows 3.x. If there is a super great MS-DOS version available .., Ok! (Sorry for my English :-) It should have this features: + Operator profile + Logbook Data Entry Callsign, Date, Time (from/to), Frequency (or Band), Mode, Report, Power, Name, QTH, QSL exchange: Y/N Yes: via Bureau via Manager: Callsign Direct: Callbook or Address (data entry), QSL: sent/received Notes: 'unlimited entry' would be fine Default entries: Date (Time(s)?), Band, Mode, Power, QSL-ing. Would be nice: + last QSO at (-/date, band or freq.) + good for dxcc, iota, .. + powerfull interface to a callbook CD + radioclub station logbook: operator is: Callsign (+ Name) + Logbook Data Management: Modify, Delete, QSL(-ing), etc. ... Very important for me are configurable listings (screen, printer, to file) + which data I wish to see (Callsign, date, frequency, QSL-ing, ..) + show it at position .. + in order of (Callsign, date, frequency, QSL-ing, ...) + date window: from .. to + prefix window: only that prefix, from .. to .., lists (from .. to ..) + frequency/band window: only that band, lists (ie.: 20,17,15) + QSL-ing windows: QSL-ing via bureau QSL-ing via manager QSL-ing direct + QSL window: sent/received + award window ("let me see DXCC or IOTA or ..") => => window combinations should be possible! + Data Backup Feature + Data Interface: listing to file :-) Any recommendation? :-) Have fun ..

I just think about the possibilty of the PGP-Encryption-program in amateur radio: A ham is only allowed to use "open speech". But signing a message with the program PGP might be ok. It could reduce the possibility of pirates in amateur radio using others call sign to work in Packet Radio. Any comments are welcome 73 Thomas Pagel Internet: thomas.pagel@unnet.wupper.de PR: DL2ECK@DB0IZ.deu.eu ------------------------------ Date: 19 Oct 1994 21:46:50 -0400 From: thayes@hardees.rutgers.edu (Tim Hayes) Subject: PGP-Signatur in PACKET RADIO Thomas Pagel <Thomas.Pagel@unnet.wupper.DE> writes: >I just think about the possibilty of the PGP-Encryption-program >in amateur radio: >A ham is only allowed to use "open speech".

In the USA a strict reading of the amateur regulations would prohibit the use of PGP for signatures because the signature is actually an encrypted MD5 digest of the message; you can't use encryption for hiding any information. I doubt the FCC would ever bring any action against an amateur using PGP signatures though. For one- the MD5 digest can be computed from the original message so it would be difficult to consider it as being "hidden". Also, since the signature is use for authentication purposes it may be legal anyway under a less strict interpritation of the rules. Using IDEA to encrypt your message would be illegal though so don't try and send PGP encrypted messages around the USA! (Exceptions to this would be telecommand of space stations and RC vehicles which are specificaly exempt from this prohibition of the use of codes and ciphers...) An intersting idea that I've been thinking about working on is a secure login facility for remote packet systems. If the remote system issues a challange string it could be signed (or even encrypted) using PGP by the connecting station. This would make a very secure login method that would be near impossible to break or spoof if the challange strings were carefully selected and used only once. Unfortunately I don't have the time.

Feher) Subject: Touch Tone Paging (DTSS) Hello Everyone! 's wonderin' whether touch tone paging should/shouldn't work via a repeater. When I try it simplex, I page the other HT and it opens up its squelch, no problem whatsoever. Same thing doesn't work when going through a repeater. Would it not work cause the repeater shifts the touch tone frequencies and they are therefore not recognized by the receiver expecting the codes. I did indeed wait till the repeater kicked in to release the three codes, even done it manually ... without success. Whatsgoinon?! Thanx for readin'!
