Welcome on 4F7RWW Homepage
I am class "A" Licensed HAM since many years and use my Cebu House as my Contest Station.
Previously to the 4F7RWW call I held in Manila the 4F1RWW call until September 2000 and before this operated out of Manila as DU1/DL5ZAH (1994 to 1998). I am a fan of CW operation and contest competition.
I am an active member of several Amateur Radio Clubs in the Philippines and Germany.

The Elecraft K2 QRP Transceiver is an excellent Transceiver
Kit easy to build and without the need of any kind of Test Equipment.
It operates with up to 10 Watts only and has all the features you request from a modern transceiver and all is a do it your self Kit.
|I bought this Kit in September 1999 and assembled it in
only 35hours. It worked on the spot and it is a very easy to build Kit,
absolutely perfect. In matters of support by Elecraft, I never had an
equipment with an support like this, unbelievable top of the line what
Elecraft is doing.
The K2 was designed from HAM's for HAM's.
It is operating on all Bands, all modes with an Power adjustable from 0.1 up to 10Watt. Features like in one of this big expensive Rigs, you can buy from Japan and all extremely small and portable.
The price believe it or not the Basic version for less then 600US$.

Direct QSL for 4F7RWW send only to my QSL Manager DJ6OI.
Do not send
the direct to the Philippines or
via Buro to 4F1RWW, 4F7RWW, DU67RWW or DL5ZAH,
since the QSL will be not be answered at all!!!!
Send your QSL only via DJ6OI .
Direct send Cards are not required, you can
use the Buro as well.
Read also my comments about sending a QSL card to a DX Station.
E-QSL for closed LogBooks
get your eqsl (electronic qsl card) for our QSO´s. If I require your QSL Card on paper I will send you one by buro or direct.
For your eqsl click on the eqsl label.
Direct cards for my Philippine 4F1RWW and 4F7RWW Calls should be send only to:
Po. Box 1117
Visit the Homepage of my QSL Manager Thomas.
Please read Direct QSL-ing comment and information first before you send you valuable card.
Direct QSL Card recommendation:
1. Check out my ON-LINE Log book if our QSO is
logged. I make sure to verify all parameters
like Date, Time, QRG, if I cannot locate your call. To eliminate mistakes on my site.
2. Use only IRC preferable before money. JA OM's do
not send this fancy IRBS envelopes, we can not use them in DL or DU,
they are without any value! Your card will be answered by BUREAU.
3. If you have to send money, use 2 US$ (two US$), this is
enough to pay for an Air-Mail from Germany to anywhere for one
QSL Card only. Insert the money in the return envelope, it is more difficult to detect it inside the second envelope.
4. Please note 1 US$ (one US$) is not enough to cover the
cost for an Air-Mail Letter from Germany. QSL arriving which do
not have sufficient founding will be answered by Buro. Two US$ (2 US$) is the amount currently needed to cover the cost
for an air way bill letter to abroad. My QSL Manager Thomas, DJ6OI, will strictly implement this procedure. We do not
want earn money on direct QSL request, but we do not want spent it either. Please understand this guideline.
5. Take note of my QSL Card size 14.5cm to 10.1cm (US
amateurs attention 5.7'x4' !!!!)
and enclose an envelope what could accommodate my card. Otherwise enclose only an address label, we do have glue and some
6. SWL, I am always very happy to get a QSL from a SWL and we
will take time to answer the SWL very detailed.
But make sure you catch up at least one of my QSO partners call correctly! I prefer the old fashion way in
decoding CW..............:-)))) DX-Cluster SWL's are cheating only themselves...
My QSL Card just came out the printing press this February 2001 and card are shipped now.
