Hi, thanks for the contact.
I got the license in 1982 with former radio call sign IW7APU. My interest is to restore and modify old radio marine equipment for the use on ham bands. If you want exchange informations, write to my email (email@example.com).
In my shack (2012) :
Activity updates (18.05.2013)
I have assembled a station operating on new MF band 472-479 kHz in CW and digimodes. I started with this WSPR and JT9 setup:
Receiver used is JRC NRD-92M. It works fine on MF.
Tx- Exciter is one old marine radiotelephone exciter from ITT Espana model ST428/M. After my modifications it works from 350 kHz to 28 MHz (frequency selectable) with 100mW power out and it has now a high stability frequency reference oscillator. Ugly equipment but it works good.
Power Amp. is built with two pcb's coming from one JRC marine MF reserve transmitter assembled in one industrial PC box. Power out measured with BIRD 43 is about 40 W on dummy load.
Antenna (provisional) is one 7 meter vertical whip (ex JRC lifeboat radio) with 5 radials (8 meters) as ground counterpoise. To improve a little bit the performance i have added four verticals wires in parallel to the whip (similar to Dieckmann & Klapper MAS140). Antenna is matched with one variometer (taken from lifeboat radio) installed inside one ex-JRC tuner.
First contact in JT9-1 was with DL4YHF on June 14th, 2013.
Thanks for your attention and CU on 630 meters band !
