Subject: [Elecraft] 630 meter band open for use

Since we finally have the 630 meter band open for amateur use, (after you
file intent of operation with the UTC and wait 30 days),

is there any plan to put this band on the K3/K3S band plan?
Would sure be nice to be able to get to 630 with out going through the
settings to enable/disable etc.
Or publish a macro that could be used with PF1 or PF2 to engage the band
quickly.

Just submitted my data for both bands. I got the lat/long from
QRZ.com and checked it against the "Maidenhead" app on my cell phone.

Interesting in reading the FCC notice, ALL modes are allowed!!!  So some enterprising company should make a transverter for us???????  It is only allowing 5W EIRP, a signal generator and do +20 dBm, Hummmmmmm.

Yes, +20 dBm would do it if the antenna and transmission line efficiency
were a perfect 100%.  A no-loss transmission line and a full size dipole
or vertical.

With the small antennas (with respect for wavelength) that are typical
for that band, very low antenna and transmission line efficiency is most
likely quite low.

EIRP is stated to account for those losses, and more power will be required.

Not broken....  just a line break that breaks the "linkification".  <wink>

Copy/paste of the entire link gets the document open.

App/notice submitted...  Thanks.  Can't imagine that I'll be up on those
bands anytime soon, but it will be nice to know if I CAN go up from my QTH.

73,

Bill,

I could not believe it when you stated all modes allowed, so I
checked the CFR47, 90.307
https://ecfr.io/Title-47/se47.5.97_1305

  630m allows RTTY, data (see 97.307 (3)

  630m phone and image (see 97.307 (1)(2)

But seriously no 3-KHz phone should be used since one QSO would
occupy nearly 50% of the 7-KHz wide band.  I'm astonished that the
FCC permits phone on 630m.
CW and digital is most efficient use of spectrum and weak signals.

97.313
https://www.ecfr.gov/cgi-bin/text-idx?SID=2689706e634fb3e73b9f4ef814c352e9&mc=true&node=se47.5.97_1313&rgn=div8

(l) No station may transmit in the 472-479 kHz (630 m) band with a
transmitter power exceeding 500 W PEP or a radiated power exceeding 5
W EIRP, except that in Alaska, stations located within 800 kilometers
of the Russian Federation may not transmit with a radiated power
exceeding 1 W EIRP.

So this observes that 630m transmitting antenna are expected to be
very inefficient 500w resulting in < 5w erp.  My inverted-L
calculates to be 3w erp with 100w.

So Mel +20 dBm (100mw) will result in about 3mw erp using my
antenna.  Of course you may put up a full size vertical 521 foot high
(with 521 foot ground plane) or a 1142 foot dipole only 1000-foot
high.  Most of us will use antenna under 10% full size with resulting
dismal efficiency.

But 5w erp can go a long distance on 630m; my signal was detected in
Buffalo, NY (about 4,000 miles).

From the ARRL announcement today:


"This notification process will ensure that amateur stations seeking
to operate are located beyond a minimum separation distance from PLC
transmission lines, which will help ensure the compatibility and
coexistence of amateur and PLC operations, and promote shared use of
the bands."

Aha! So PLC and amateur radio DO interfere with each other after all.


In the end, amateur radio operators have been vindicated on this point.

We've had these bands in Europe for years and AFAIK nobody uses voice
modes. The IARU R1 bandplan suggests a maximum bandwidth of 500 Hz.

AN/CRT-3 [aka BC-778] "Gibson Girl" survival radio.  The ones we had in
SE Asia in the 60's included a rock-bound 8 MHz distress frequency too.
