It is possible to tune the 1103 receivers below 100kHz, and to 
disconnect the internal ferrite rod antenna on MW + LW, by using 
this simple procedure with the SCAN function.

Normally, a 'scan' will remain within the selected band, with 
the tuning scale showing progress through the band. If you start 
a scan from outside a band, the scan will become 'trapped' within 
the next band that is reached. However, starting between 1 & 9kHz 
above any band upper edge and scanning down, will bypass the 'band' 
system, and will not switch to the ferrite rod in the range 1710 - 
100kHz. The tuning will also continue below 100kHz.

So, select 1711 by direct entry:
[1] [7] [1] [1] [band+/AM]
and scan down: hold [BAND-] for 2 seconds.
As soon as the frequency is below 1710kHz you can stop the scan and 
use the rotary control, or you can let the scan continue below 100kHz. 
The antenna is now switched for the telescopic or external antenna.
I suggest you tune it down to zero and store this in preset 0, or store 
99kHz in preset 99. Also store any frequencies for which you wish to 
use the external antenna input. You can store any frequency with the 
[SSB] mode 'on' for CW reception.
Once you enter a frequency or change band on the keys, the system will 
revert to the normal tuning range and with the ferrite rod for MW + LW.
===========================================
There is a widely held belief that you must start the scan at 21951kHz 
because that was the designer's employee number, but that is nonsense, so 
start at 1711kHz and save time!
===========================================

There is another procedure at http://mods.radioscanner.ru/degen/mod29/ 
for tuning above 30MHz (AM), possibly up to 35 - 37MHz depending on 
hardware alignment
===========================================
A recent posting on Youtube seems to promise a way to tune an 1103 
to the OIRT FM Band below the specified limit of 76MHz, in 10kHz steps:

I do not understand his procedure, which seems to be random, and I cannot 
persuade my DE-1103 to do it, so if you have any ideas please mail me
