Hello LF enthusuasts,

The german "Regulatory Authority for Telecommunications and Posts"
recently published a questionary to evaluate the market's needs
for low frequency allocations.

Details (these are in german - sorry) can be found at the following URL:

http://www.regtp.de/Fachinfo/Langwelle/start.htm
and
http://www.regtp.de/Fachinfo/Langwelle/amtsbl.htm


In essence, a.m. german authority plans to re-use a set of frequencies 
(allocated to germany on primary or secondary basis according to the
IFRB / ITU) in the LF range, which is internationally allocated to the 
fixed service and navigation service.

The following 11 frequencies are involved:

(1)	46.250 kHz 
(2)	47.450 kHz 
(3)	55.250 kHz 
(4)	69.700 kHz 
(5)	94.500 kHz 
(6)	110.550 kHz 
(7)	117.400 kHz 
(8)	131.400 kHz 
(9)	136.800 kHz 
(10)	146.000 kHz  
(11)	147.300 kHz 


Especially interesting is the list of former usage of those frequencies,
contained in the "amtsbl.htm", which I compile here for better readability:

==List start ==================================================
(1) frequency		46,250 kHz 
station site		Mainflingen 
bandwidth / modulation	1K20	A7B-- 
max power into antenna	+ 37.0 dBW 

(2) frequency		47,450 kHz 
station site		Mainflingen 
bandwidth / modulation	400	HA1B-- 
max power into antenna	+ 40.0 dBW 

(3) frequency		55,250 kHz 
station site		Mainflingen 
bandwidth / modulation	1K20	F1B-- 
max power into antenna	+ 40.0 dBW 

(4) frequency		69,700 kHz 
station site		Konigswusterhausen 
bandwidth / modulation	2K10	A2B-- 
max power into antenna	+ 43.0 dBW 

(5) frequency		94,500 kHz 
station site		Konigswusterhausen 
bandwidth / modulation	1K10	F1B-- 
max power into antenna	+ 40.0 dBW 

(6) frequency		110,550 kHz 
station site		Bad Vilbel 
bandwidth / modulation	1K00	F1B-- 
max power into antenna	+ 44.8 dBW 

(7) frequency		117,400 kHz 
station site		Mainflingen 
bandwidth / modulation	2K40	F1C 
max power into antenna	+ 40.0 dBW 

(8) frequency		131,400 kHz 
station site		Kiel 
bandwidth / modulation	600H	F1B-- 
max power into antenna	+ 30.0 dBW 

(9) frequency		136,800 kHz 
station site		Pinneberg 
bandwidth / modulation	500H	A1B-- 
max power into antenna	+ 31.8 dBW 

(10) frequency		146,000 kHz 
station site		Konigswusterhausen 
bandwidth / modulation	1K10	F1B-- 
max power into antenna	+ 43.0 dBW 

(11) frequency		147,300 kHz 
station site		Pinneberg 
bandwidth / modulation	500H	F1B-- 
max power into antenna	+ 31.8 dBW 
==List stop ==================================================

Isn't frequency (9) right inside the frequency range
allocated to the radio amateur service (on a 
secondary basis) ???

What does this say to us in lieu of usability of the
LF band in future ???

This information is useful to update frequency lists held by
several OMs, as it constitutes the official and legal limit
of frequency usage of the past.

On the other side it may throw a shadow on possible future
usage as well and give an impress on what we may expect
(more QRM) on the LF range in the future.
