Unless money is changing hands, why bother with signatures?
Most of the emails sent are just yak and opinions. If I don't like it or care, I delete. If someone's going to the trouble of spoofing an email from you, emailing erroneous opinions to the email list is probably not their target.

If you're making a deal with someone to buy/sell things, then it might be worth considering.
For moderately priced items (dollar amounts I'd be really sad to completely lose), I'll want a phone call or check that your email is the same one I'm sending money to via PayPal (and that you've used that address for some time).

The recent thread is all the more reason to use tools such as
cryptographic signatures where possible, IMO.  Unfortunately, some
amateur radio mailing lists block signed messages and I must send
messages to those lists in the clear (all of the Linux related lists I
subscribe to accept signed messages).  Now, a cryptographic signature
does not prevent someone from spoofing my email address, but if it's a
direct mail from me and it's not signed like this one is, then the
recipient can be assured that it wasn't from me.                                                                   

The spoofing of email addresses is a problem but it doesn't necessarily
mean that an account was cracked.  However, when using a cryptographic
signature, the spoof is easily identified as the spoofer should not have
access to the private key used to sign the email nor should he know the
password to unlock the private key for signing.  An email client program
will check the signed message against the public key which is often
available from a public key server and verify the signature.

Re: Cryptographic signatures

 

As I understand it now, Groups.io munges the email body by inserting its
own footer at the end of the message. Since the cryptographic signature
does not include this extra text, the signature test fails with the
result being a bad signature. The footer, as Groups.io calls it, cannot
be removed as mentioned in the FAQ at the bottom of this page:

https://groups.io/g/GroupManagersForum/wiki/Footers

I am subscribed to many other lists, mostly about Linux or software
development on Linux and all pass the signed data correctly. Even our
club mailing list hosted on QTH.net passes it correctly and adds a footer
that is separate from the signed message body.

Anyway, I wanted to close this thread and say that what I thought would
be a useful tool for us is made useless by the mailing list host.

The ten meter folks used to have a backscatter net. They basically pointed their antennas away from whomever they tried to contact. Dunno if this would work with the current low sunspot count.

Thank you all for your emails about SSB...I am having to do some downsizing and made the decision to specialize in SSB. The XYL is delighted in the reduction of my gear and I can focus on getting a couple of things done instead of being surrounded by things that others might enjoy. 

Please let me know of QRP SSB activities or groups.

4SQRP has a SSB Group that around 60 have signed up for messages so I believe that there’s interest, someone needs to pick a day, time, frequency and so on.  I would be willing to be an alternate NC.

I get much more enjoyment from a single QSO at 5w than 10 @ 100w, especially when operating on battery power and with homemade antenna systems.

I’m all in ,

*******************************************************************************

EXCHANGE

The exchange for this event is:
CALL SIGN
RS / RST / RSQ
STATE / PROVINCE or COUNTRY

Bands & Modes

All HF bands will be in play, including the WARC bands, with the exception of 60 meters. Simplex on 2 meters and 6 meters is encouraged.

The SE stations are on the east coast and, are very close to each other. It will be harder for these states to contact each other so, use of 40m-160m is encouraged.

All modes of operation may be represented - SSB, CW, RTTY, Digital, Etc. - The mode of operation is up to the individual colony state station. Please refer to the State information pages for details.

The 13 Colonies Special Event is a not for profit event. All donations are used to fund the next years event, and to defray any expenses occurred. All donations are used for operating costs, supplies, equipment, and 13 Colony Group initiatives. Donation is voluntary. If you have difficulty with a donation, tell us on your log sheet, and we will send you the certificate earned-No Questions Asked!.

Dear Dan,

    Thanks for the reply.  I got a couple of stations last year from 13 Colonies. This year I am busy getting my house ready to sell. But I will be caught up by the end of July and will more time to get on the air. I have only been a Ham about 2 years and really on air a little over a year.

        For my 100 watt base station I have a Kenwood TS-520S station (first HF rig) and ICOM 706 MKIIG (will go in my truck once I work out antenna issues) and an ICOM 718 (which will become my field day rig). All of these use a 37 foot End Fed Antenna at 30 feet to the East in a tree and 15 foot to the West on a pole hooked up to a little MFJ tuner.

    I was at the 4 State QRP Conference this year and came away with a better appreciation for QRP work. Really wish CW would stick in my brain. I picked up a nice FT-817ND for a very good price to play with, so I am building a backpack QRP rig to work with. Going to try some Parks On The Air and Peaks On The Air things later in the year. I have also signed up for the NJQRP Skeeter Hunt in August.
