Hi all
I have been a member of many email lists over the years (discussion groups) and this question of splitting into sub-groups sometimes comes up. It always seems controversial. Some people want to split, some don't. There are other companies like Elecraft, that are a lot bigger than QRP Labs, who have only a single discussion group for all their products, and they manage perfectly well. They also had "split discussions" at least once that I can remember - and it did not split. BITX is having that discussion lately.?
If the group is split there is a good chance of information and assistance becoming fragmented. People may post in the wrong group, and sometimes a question may be generic enough that people from another group would be well-placed to answer it, but don't because of the split. When a new product is announced, there may be people who want to hear about it and discuss it but who will miss it. And the question is also, where it will end - QRP Labs already has quite a number of products, QCX being the most recent - how should the group be divided up? QCX vs "everything else" - or "everything else" should be further sub-divided too??
Overall I am not 100% sure I have a firm opinion, but I tend to think that it is better to stay as one group - and if people wish to filter out say QCX messages, then they could do so at their own mail client.?
Bear in mind also that the QCX is very new and always in such cases, there is a high volume of emails to start with, and they gradually reduce over time.?
This group has an excellent atmosphere and a critical mass of people who are willing to help each other and share their experiences. Many times the group members help answer questions people have, and I do not need to be even involved - which is great because I have very high workload already and need to try to spend at least a little time each day developing the next big thing :-)? ?The group also is very well self-regulating, it does not require much in the way of moderation, people generally don't fight, as I have seen happen in some groups. Since it all works so well - I'm a bit reluctant to mix it up and risk it NOT working as well.?
On the other hand I do take the point that some messages are superfluous, are solved on the FAQ or in the manual, etc etc. Maybe it would be useful for me to write a monthly "group etiquette" email, and that would reduce the size of the problem? Something like:?
1) Remember your email goes to up to 2500 people - is it something you really want 2500 people to see? 2) Before asking a question, please ensure you have read the relevant manuals and web pages thoroughly, to see?if your question is already answered somewhere. 3) Also check the FAQs and ?
4) Don't write about your kit arriving. Send that to sales@... instead - where it is compiled into statistics published here 5) Please don't write "Happy Christmas", "Happy New Year" etc messages - it's very nice of you but imagine if all 2500 members wrote it... 6) It is nice and friendly, to provide your name and callsign - or if you wish, you can add a photograph and whatever details you like, to your profile:? /account?page=profile&profilesubid=0

A bit arrogant perhaps, but sometimes a healthy dose of RTFM and SEARCH is the proper route. Perhaps too easy to just ask before doing the reading/searching...
Before posting one should be aware that a good part of 2500 (as of now) people are going to see this in their inbox. There's a good chance of everything drowning in the noise if it's not managed. Hope to be of any help and looking forward to being part of this in the forseeable future. 73's and happy holidays.

Don't think so, the old Heathkit manuals included detailed schematics which I find a lot more useful than color pictures.

Sadly I'm getting swamped with posts complaining about too many QCX
messages. Remedies are simple. Use the delete key, start an entirely new
group, or figure out how to create the sub group being talked about.
Personally I like to read all the posts no matter the subject.
I wish everyone a merry Christmas, happy Hanukah or what ever holiday
someone may celebrate this time of year.

Re: Hans Writes re QCX in RadCom
Brilliant, he takes a cracking picture!!

Note also that there's a review of QCX by Hajo DL1SDZ in the January edition of CQ DL which I believe German DARC members will have received about now. The junior lab tech got his picture on the front cover of the magazine! See? about half-way down.?

Re: 40 m QCX on the air with an interesting enclosure.
hi Georges!
what value of the menu items 3.8, 4.8, 8.2, 8.3, 8.4 you installed for 480 Hz?
|
Re: 40 m QCX on the air with an interesting enclosure.
Hi Bill,
As far as I know, the decoder central frequency is 700 Hz. The filter bandwidth is about 200 Hz, so it will certainly work.
Hans plans a firmware update with the choice of different central frequencies for the decoder, and I believe 600 Hz will be one of these.
Best regards .

Thanks Mikael,
your suggestion works for me. I does not seem very long before a new thread goes totally off topic too, so I can now filter stuff for relevance.

Hi Hew
Some people don't use a shielded cable between Ultimate3S kit and GPS. I recommend shielded cable because it is never a bad thing, and sometimes a good thing. Same applies to the QCX.?

Is a shielded cable also required on the GPS QCX interface ? There is no mention of it in the QCX manual that I can find.

If you bought a low pass filter kit, it looks like the shippers made a mistake and sent you a bag that was supposed to go into a QCX kit.

Just got the qcx up and running but I have a small issue. When I go to adjust the IQ balance or phase high and low, the lcd shows no movement on the bar. I can go from one end of the pot to the other and nothing changes. What could I possibly be missing here?
