I remember 78xx needs almost 2v above the output voltaje to works fine,  If you want 12v and use a 7812, the component needs almost 14vcc. 

First off, I'd like to say hello. I joined radio preppers yesterday so look forward to catching up on some reading here. I have been a technician since 2013 and have mostly 2m band from my vehicle, no base station. However, within the last year I have ordered and built the QRP Labs QCX 5W kit for 40m, which works amazing for the $49 that I paid. I am in the process of learning CW from lcwo.net and the K7QO Code Course from FISTS store. I also include listening in on 40m as daily practice with the MFJ 1984-LP (end fed half wave) as my antenna. So this leaves me with a few questions. For qrp operations while out hiking/camping, would a radial be beneficial or do I even need one? Does it need to be grounded? As I mentioned earlier, I'm still learning so I won't be doing any transmitting at all but I want to take it camping next weekend, set it up and listen in on all the QSO's. Any help or advice would be greatly appreciated. Thanks.

Yes!

Radio Relay International is awesome.  It's real communication, and reading through the after action report from the Cascadia Rising exercise produced by the U.S. Federal government , it put a smile on my face to see Morse operators juuuuust slightly win over the excellent PACTOR network.  Another factor in this exercise was to simulate the depletion of fuel reserves used for powering ham and municipal generators, which took some of the heavy data centers off the air, as would happen in an actual disaster of this size. The energy efficiency of low/medium powered CW with trained/experienced operators handling traffic really became extremely useful.

Remember: If you can't power your communication equipment, you cannot communicate.

Well, that being said, I’ll just quote the most important parts of the thread:

“Seasoned CW Operators Needed

 Marty N*** Apr 26   #116022 

Seasoned CW operators, Uncle Sam needs you, well actually the traffic system needs you. Operators at all levels are needed, but I am putting out a specific call to those of you who are a little more seasoned to fill urgent needs in some special assignments. Traffic handling experience is desired, but not required, as training will be provided.

We all enjoy the amateur radio service as a hobby, but we also have an obligation to serve. Traffic handling is an enjoyable endeavor and it provides a life-line in the event of a catastrophic event.

As I mentioned above, operators are needed at all levels and I would like to hear from all of those who are interested in serving, but there is an urgent need for those in particular who have good code proficiency.

For more information, please contact me directly at: marty.ray@...

Hi Art et. al:

We can always use people with experience or those who want to get
experience.

During a major Federal disaster exercise in 2016, the CW portion of the
traffic system scored an accuracy rate of 99.998 percent across over 10,200
data points. The CW networks also scored the shortest message propagation
times, that is; the time measured from when a message was tendered for
origination in the simulated disaster area consisting of Alaska, Northern
California, Idaho, Oregon and Washington State, to the time the message
appeared in the data stream at the National Response Coordinating Center
(NRCC) in Washington, D.C.

CW nets actually performed slightly better than the digital networks in
terms of accuracy (the latter scored 99.997 percent across fewer data
points), and considerably better in terms of measured propagation time
through the network.

The exercise evaluation report is rather lengthy and includes quite a few
tables showing the data collected. However, suffice to say, CW proved to be
highly effective. Part of that success was related to the operators
involved. Many had commercial or military experience while others were
experienced CW traffic operators with regular net experience and solid
communications skills developed over time. Simply put; *there is no
replacement for training and experience.*

Traffic nets are an ideal way to learn REAL communications procedures. One
must communicate over specific distances, at specific times, and under all
propagation conditions. After all, disasters don't wait for optimum
conditions. Perhaps equally important is the fact that the message content
varies considerably. Every address is different. Telephone numbers and
e-mails are unique. The variety in traffic work far exceeds the predictable
content of casual QSOs or contest/sprint exchanges. If one can perform
effectively on traffic nets, DXing and contesting will come much easier.

Most importantly....it's fun and challenging. There's real camaraderie in
traffic work.

Here are a few resources to get one started:

Marty is right....we need a deeper bench and we need to be bringing new CW
operators into the system. Last year's hurricane season proved that Amateur
Radio is still needed in major disasters.  Why not learn how to properly
assist now?
