JO7KMB is QRV now!

Hi, this is DV1/JO7KMB.

I returned to JA on 16 Jan 2013.

During my stay in DU land, I could enjoy amateur radio through Philippine Amateur Radio Association and my friend's efforts.

Many thanks to all of my DU friends and see you again on the band/ground.


YOU MAY SEND YOUR QSL TO THE BUREAU since I am a member of JARL now (QSL forwarding service, maybe till Mar 2015).

During that period, I can send you my QSL via the bureau! (Not only for JA members but also for foreign countries' members).


My QSL policy is;

1) I do LoTW within a week, after QSO.

2) Via the BUREAU (Please send to JA bureau, via JO7KMB only. Do NOT send to the Philippines!)

3) Direct (SASE or SAE +)

*You may QSL at one time, need not separate SASE or SAE +.

I handle QSL for DV1/JO7KMB, JO7KMB, JK1AJX & 9M2JI (All QSO data, since 1978 were uploaded into LoTW).


You may check CLUBLOG for QSO with DV1/JO7KMB...

If you cant get your call sign, please give me an email anytime. I will check my EasyLog carefully.

I am NOT

BV1 / D41 / DU1 / DU / DV

but DV1/JO7KMB.

Please check your log!

Thank you.

I am working here in the Philippines since Feb 2008.

With cooperation and effortsby DU friends, I got license in Feb 2010 and started to QRV as DV1/JO7KMB from Makati city, Metro Manila (IOTA: OC-042 & GL: PK04).

I put up a long wire antenna from my 27th floor room. Tried 20m to 40m length and finally set 26m.

Got upgraded license and bought KPA500 amplifier in late May 2012. Sometimes I use it at 150 to 250W output with SG235 auto tuner.


Now many new condominiums are coming up and noise increased very much.

To reduce noise, I switched long wire to loop (since Jun 2012).

With this loop, I worked OH8X, Radio Arcala, a big antenna station on 80m with 80W output.

Loop with SG235 (SG237 for 6m, not yet use). When switch to long wire, connect wires as counterpoise

(JUN 2012)


Long wire with MFJ fishing rod and SG230 (FEB 2011)


Long wire with real fishing rod (5.4m) that I used for fishing before (FEB 2010)


My JA friends told me that many Eu stations called me. I am sorry but most of the time I have very heavy QSB here. I know also you have QSB and QRM there. So please listen carefully and call me few times.

Looking for DX specially on 80m and 160m. Please listen carefully if you heard weak signal, maybe I'm calling you!
