>>K0UA   I tried some extra cables, but will grab another and get everything ready and then shoot you and email for availability tomorrow or next week.  TY  very much for your prompt and kind offer.

Did you have your FRN prior to taking the exam or did you use your SSN for examination purposes?  It may very well be the password is coming via snail mail.

The ULS will accept either an FRN or an SSN on the Form 605 when taking an exam.  The preferred method is for the candidate to obtain an FRN prior to taking the examination and using this number of the Form 605.  If the candidate does this then they would have created the password at that time.  If a candidate uses their SSN on the 605, then the ULS will assign an FRN automatically and generate a password for it.  This will then be sent to the new licensee, although I'm not sure of the method. (My VEC uses FRNs only.  We will not accept a 605 with an SSN because we don't want to be open to potential identity theft accusations.  It's a CYA situation.)

If you received your license just within the past several days, I would wait and see if your password arrives in the mail.  If you haven't heard anything within a reasonable time, then contact the FCC.

To follow up on the matching requirements:  an end-fed wire of reasonable
length (not real short, say 20' or more) can usually be matched with a simple
L-network tuner.  When the wire is less than 1/4 wave, use just the series
coil and set the capacitor to minimum (or switch it out of the circuit.)

Between 1/4 and somewhere around 3/8 wave or so (depending on the
configuration), use just the series capacitor, possibly with a bit of coil in
series with it if needed.  Beyond that the L-network should match most
wire lengths, though a 3/4 wave wire may not need a tuner.  Efficiency may
be best with something close to 1/2 wavelength if you have the supports
for it, and the L-network should match that easily.

Radio have issues, no doubt. I would suspect that when bought Xiegu or Baofeng 200$ rig nor 4000$.
Radio with no issues i can tell about my TS-870 I use since 14 years without any glitch.
I was going to buy 7610, but after all I read I hold till revision 2 or 3 will be released.
I do not want to be beta tester.
I think, that all 7610 with issues should be  sent back and refunded, that would speed up Icom engineers to fix the problem.
I will laugh loud when warranty will be gone and you will stay with faulty 7610.

I have a CW Morse code trainer Android app that does what you ask. It is available on Google Play and the Amazon Appstore:

You could be totally deaf and operate any digital mode. Hearing can help a bit for tuning or timing, but I have operated  totally without sound and it works fine. It is all visual. As said you hearing isn't going to get any better and SSB and CW are going to become more difficult.  Welcome to the digital world.  Smiley

SHARES is FEMA's organization for emergency mangers and agencies to use to communicate. Yes, sometimes it is manned by amateurs and sometimes by officials.

The radio equipment and modes it uses are highly restrictive, with hi stability required, and only Pactor III or IV connections allowed on digital.
Curious as to why Pactors 3 and 4, since the price tag for modems ranges from $1200 to $2000.  WINMOR 1500, on the other hand, runs Winlink just fine on a sound card.......  And, if Uncle Sam is paying for the modems, I really do have heartburn.....


Although Pactor may be a requirement within SHARES's Winlink operations (I'm not sure), I am reasonably confident that there are other digital modes available, for which SHARES ham/MARS volunteers have soundcard-based tools available for use.

As to why SHARES might limit Winlink use to Pactor...I'm just guessing, but it might have to with how the "professional" SHARES stations (federal agencies, etc.) may be staffed by appliance operators.  They have the budget for hardware modems, and Pactor modems do tend to permit the "it just works" style of operation that  appliance operators need.  Throw in P3 and P4 having generally better throughput in real world conditions than Winmor, and....those who have budgets can get Pactor modems, and those who don't can use other non-Winlink digital circuits.

Use a thin, flexible wire - something like #24 or #26 stranded.  If you really want
to be authentic you can try to find some woven phosphor-bronze wire, but for
your purposes some plastic-covered hookup wire should be fine, especially
with black or other camo-colored insulation.  (Brown with green stripes works
pretty well...)

Antennas were often a random wire fed against ground, so you will need some
sort of tuner to go with it.  The original radios had adjustable output stages
that served this function.  You can try just using a quarter wave wire with a
second one laying on the floor as a counterpoise, and you might get by
without a tuner, depending on how fussy the transmitter is.

When I teach the antennas part of a license class, we usually string up a 15m
dipole across the room to demonstrate how to tune it.  In most cases, I can't
find suitable attachment points in the room, so I recruit a couple helpers at
each end to hold the antenna up.  (This will be harder with younger students
who aren't as tall.)   In your case, I'd set up an inverted "L" with most of
the wire horizontal at whatever height you can manage, and enough wire
leftover to drop down to the rig.  Then you can add about 5' or more of
nylon string on each end between the wire and the "supports".

You'll have to test it ahead of time to see if ground wave (vertical polarization)
or NVIS (horizontal) gives best coverage at that time of day at your latitude
with the current propagation conditions, and optimize the antennas at each end
accordingly.  You may also run into noises from lamps, networking cables,
etc. that make it difficult to heat the other station.  (An outdoor antenna
would be better in that case.)

The "NEW" FT 818 ? What a joke.

There must be something more than what is being published so far, if not, not sure what to think of this 'new' model.

They 'milked this cow dry' for close to 20 years. New quality QRP radios have been released in the intervening years, and this is all they can come up with.

There is always a segment of the market that will buy a new radio, not matter what, bragging rights are very important to some people, but I can't see the 818 selling like the 817 did while it was 'king'.
