It is about 100 miles across the Mona Channel. That is a longshot on 2 meters, but I got the idea when, this past summer, I regularly heard WIDI 99.5 FM in the Dominican Republic from western Puerto Rico. So over the fall I gathered 2 meter gear, and got a directional antenna and sent all of this gear to the DR.
Here is the antenna. Seven elements. I got it through Amazon. It came kind of incomplete and without any written or on-line instructions. AI told me to do exactly the WRONG thing with what they assumed was a reflector. Fortunately I ran into this YouTube video and learned that it was in fact a "ZL Special" antenna, and that it has, in fact, TWO driven elements. It was through that video that I learned how to assemble this thing.
My "station" consists of a Heathkit HM-2109. It is a VHF wattmeter/SWR meter that I bought by mistake. But I kept it, and it proved very useful in this 2 meter Mona Channel project. There is a Baofeng UV-5R (boo! hiss!) and a Yaesu FT-470 that KD4EBM gave me. I have a Communication Concepts 2 meter amplifier -- I must have picked this up at a hamfest. It promises 35 watts with 5 watts of drive. The old CCI amp gives the rig good juju.
This morning I wrote to the hams of western Puerto Rico:

Saludos desde el otro lado del canal de la Mona!
-----------------------------------------
Greetings from the other side of the Mona channel!
I am a radio amateur: Hi7/N2CQR. We live in the Dominican Republic in Cap Cana six months every year.
I've noticed that I can listen to WIDI 99.5 FM here.
There seems to be Tropospheric ducting.
Two FM transceivers
An amplifier at 35 watts. \
A 7-element directional antenna with a gain of 11.5 db.
I am at an elevation of 7 Stories. I can see the Mona's
channel.
-------------------------------
Stay tuned!
Do a 2 Meter CW Beacon Bill! It can run when you aren't on 2M FM. Take the key control line from the beacon controller, and let it key a 2M CW beacon at the same time as the 10M beacon. Flip the same beam to horizontal polarization, point across the Mona, let it light up PR and the Lesser Antilles. Tropo!
ReplyDeleteInteresting idea Mike. Thanks, 73 Bill
ReplyDeleteFor £25 post paid in the UK you can get the Quansheng UV K5 FM 2m/70cms radio for which there are software tweaks that give it CW capability (lots on Youtube). 4 watts on 2m and 3 watts on 70.
ReplyDeleteNow that ought to make the distance to Puerto Rico.
[tilt that beam horizontal though].

ReplyDeleteCan you raise the beam above the tripod, the tripod legs are inside the beam. Also you might be better off to turn it horizontally...
