My whole name is Francisco Luis Escobar Bay, normally I use "Luis" in DX work.

In local QSO`s and in spanish language I use the nickname "Pancho".

My first contact with amateur radio was when I was twelve years old when a school teacher make a demonstration in classroom whith his rig label "Geloso", in AM and CW.

I began from this fact with electronic experiences and transmissions like second operator in CX2FD teacher`s station, where I learn CW, for ever my principal mode of operation.

In 1972 I obtain the call CX7AF, and began operations with homebrew rigs, including multibands SSB and CW transceivers.

My real calling is Hystopatologic Technician, but thanks to my chief hobby (another hobbies: photography and video and music; piano, guitar and bandoneón) I applied for a Job like engeneer in uruguayan governement broadcasting and I obtain a place! Thanks to Ham Radio...

I am a member of RADIO CLUB URUGUAYO and RADIO GRUPO SUR, and I am a part of club teams in contests and activations.

Also, I have part in the Team Contest CW5W.

As a member of LU-ESCUELAS group ( see: www.lu-escuelas.com.ar ) I place a radio station in schooll classrooms to teach amateur radio to kids.

My operation:

Modes: CW: 50%. SSB: 35%. Digital communication: 10%, AM: 2%, FM:3%

Bands: HF: 160 to 10 meters band.

VHF: 50 Mhz. and 144 Mhz.


Kenwood ts-50 mobile and portable operation.

Icom ic-728 main base HF rig.

Alinco DX-70 for HF and six meters operation.

YAESU FT-747GX for portable operation

Realistic HTX-100 for ten meters QRP mobile / portable operation.

Icom ic-505 for 50 Mhz portable operation.

Kenwood TR-751A for 144 Mhz base operation.

Linear amplifiers: Collins 30L-1 and AMERITRON AL-80A.

Filters: MFJ-704 low-pass filter.

Antenna tuners: Homebrew UNIMATCH, KENWOOD AT-130, JOHNSON VIKING Match Box.


Vintage equipment: SWAN 500C - Yaesu Musen FT-7 - R.O.E. meter HEATHKIT HM-102 - Johnson Viking Match Box.

Normally I operate at 100 watts or QRP at 10 watts SSB or 5 watts CW; in digital communicatios with 25 watts.

Computer: An old Toshiba Satellite 4300 series; I operate MixW 2.19, MTTY, MSSTV , in contest N1MM programs.

In CW, I use a Hi-Speed EK-100 autokeyer or a MFJ 400 / Bencher BY-1 or a LOGIKIT CMOS-4 keyer with MFJ-564 key.

Antennas: Because the architecture of the building I can`t place a tower neither a beam antenna, then I trasmit whith dipoles, verticals and a end-fire wire of 80 meters long. In mobile and portable HF operation I use a Hustler MO-2 vertical antenna. Now I am very active in portable operation, see in Facebook the group: Amateur Radio Portable/Mobile - Radioaficionados Portátil/Móvil and join !

Confirmation: I confirm 100% of QSO`s, normally by the bureau, but if you send a QSL direct to my adress I return whith mine as soon as possible.

I confirm by eQSL too, but ever I send a paper QSL.

Well, thank for your interest.
