Heres your chance to ask questions that you think may have been asked
before, or that might not require their own thread.
This is a great place to get answers about choosing or operating first
radios, as these threads often get ignored due to their frequent
reappearance on the front page. Youll have lots of eyes here.
No question is a dumb question! If youre still worried your question sounds
dumb and you would prefer not to ask in public, PM the mods!
Upvote good questions and good answers. It makes improves their visibility!
Im working on building a wiki page with a list of all previous Elmer Thread

After 7 years it finally happened...

Posted: 31 Oct 2014 12:56 PM PDT
http://www.reddit.com/r/amateurradio...ally_happened/


I figured Id pop in and introduce myself at least. Im usually very much a
lurker on Reddit, and probably still will be, however I like to be friendly!
After 7 years my friend (Extra/VE and best man from my wedding) finally
convinced me to take my tech to at least get started. Started studying on
the 14th to take the exam on the 18th, the goal being that my buddy could
sign my cert, rather than my waiting until the next session. Managed to
spend a lot of time reading up and passed with only 3 wrong. For giggles I
tried the general as well, missed 17, so a bit of studying left to do for
that I suppose...
2 days ago my call was finally posted (11 days post VE exam), but Ive yet
to TX. Currently rocking the UV-82 and mostly listening to the Lowell, MI
repeater, though Ive been poking my head in the Grand Rapids IRA as well.
Ive currently got my vanity application in for approval, so heres to hoping!

CW Headset Recommendation

Posted: 31 Oct 2014 01:27 PM PDT
http://www.reddit.com/r/amateurradio...ecommendation/


Hi everyone. I currently use apple ear buds for my cw work and they are ok.
Looking through the boards, I found that people liked military grade
H-251As due to them being non- HI FI. Here is the spec sheet:
http://radionerds.com/images/0/00/H-...tion_sheet.pdf
My question is for those of you with more electrical knowledge than I,
would there be a way to lop off the U-229 connector and switch it to a
3.5mm plug for use on a TS-480 or KX1? Worried that the Ohms might not
convert.
Right now with a 3 month old, money is tight, so I was not going to buy a
Heil or $100 plus set of cans right now with a new 3 month old around.
Would anyone have any other suggestions that they might think would work
well? submitted by NJ_WOP

FRN for test?

I was reading though the forums on eham and saw some people talking about
needing a FRN to take the tests... I thought all I needed according to the
ARRLs info on where I go to take my test, is a photo ID. Is this something
I need to get before hand? submitted by er1catwork

Anyone looking to build a simple 40 meter qrp cw/ssb rig? If I hadn't just
bought an IC-275H I would have bought it. I am talking to the seller to try
and get him to make them for other bands, you should too!!

Need help troubleshooting Ramsey Kit http://imgur.com/a/ykBOn#0

Posted: 30 Oct 2014 10:28 PM PDT
http://www.reddit.com/r/amateurradio...ng_ramsey_kit/


I tried to assemble the Ramsey FR146 2 Meter kit, and figured I had it
handled...but I was wrong.
I got the thing to turn on, but the receiver just puts out loud static. To
troubleshoot that, the manual just says "you need to verify the local
oscillator is operating. Use another VHF receiver or a frequency counter to
verify oscillator operation."
I have no idea what this means, though I know the local osciallator is the
orange thing int he bottom of the third picture. Then it says to make sure
the 10.24 MHz crystal oscillator is running, but I dont have an HF receiver
to check it (though, again, no clue how that would work either.)
Finally, it says to check the solder joints, though Ive checked lots of
them and they seem to be working, I included a few pics to see if anything
is obviously amiss: http://imgur.com/a/ykBOn#0
Any ideas out there? I tried adjusting the oscillator while there a net on
last night, but I couldnt get the thing to do anything other than put out
loud static. Any idea where to start? submitted by chandler404

Measuring voltage from radio's audio out

Posted: 30 Oct 2014 10:10 PM PDT
http://www.reddit.com/r/amateurradio...ios_audio_out/


Hi all, Im trying to measure voltage from my radios audio out to determine
when its on (receiving) and when its silent. Using a digital multimeter on
DC voltage, I see an initial reading of ~3V when the radio is receiving.
However, this value slowly drops as I continue the measurement. It seems
like by measuring it, Im causing the voltage to drop. Can anyone tell me
what Im doing wrong?
(My ultimate goal is to wire this up to an Arduino to tell me what % of the
time its receiving a signal.) submitted by completefudd

Am I doing something wrong? Yaesu FT-857D & LDG AT-100ProII + Y-ACC Cable

Posted: 30 Oct 2014 05:01 PM PDT
http://www.reddit.com/r/amateurradio...su_ft857d_ldg/


I have This Tuner for my FT-857D radio. I also have the Y-ACC Cable.
My understanding is I should be able to go to the frequency which I want to
transmit on... press the "Tune" button on the tuner for more than .5
seconds, and it should put the radio into CW mode, low power, transmit, and
tune.
However, This is not the case. . . I originally purchased my tuner near the
beginning of September. I recall it working 1-2 times, then it stopped
working. LDG said to send it in for repairs. Over a month goes, and the
notes on the repair state Unit is not repairable. Please Replace so I got a
new tuner and cable.
I hook it up today - same deal. I can transmit manually (FM or something
with noise on it) and it will then tune... but if I try to use the Tune
button, I get no results but "NO RF" LEDs. . . . .
I performed a master reset on the radio to make sure it wasnt the radio
either... same results.
Halp!
edit: It looks like the ACC jack on that radio is bad submitted by

RF Connectors: Pros and Cons? (SMA, BNC, MCX, N-type, etc.)

Posted: 30 Oct 2014 04:31 PM PDT
http://www.reddit.com/r/amateurradio...mcx_ntype_etc/


Ive been tinkering with a little RTL-SDR dongle with an MCX connector, and
Im in the process of building a planar disc antenna, which naturally leads
me to ponder the many RF connector types. What are some of the reasons you
would choose one type over another? Thanks in advance! submitted by s0lar
