QSL manager for OA4/PA3GFE, OA6/PA3GFE and OA7/PA3GFE, but not for OA4O.

My home-QTH RIGs:

HF: Currently using a quite old FT-77 transceiver running barefoot 100W or FT817 with homemade PA 130W.
Antenna: Inverted Vee for 30m with apex at 10m, fed with ladder line, tuneable from 40-10m. On 160m & 80m I use the same antenna, but as a top loaded vertical antenna fed against ground (= quite some radials and chicken wire...).

VHF 2m: FT-817 5W with 5 ele yagi, only portable /P
70cm: FT-817 5W with panel antenna, only portable /P
23cm: FT-817 with homemade transverter 18W, yagi 55 ele, only portable /P
3cm: FT-817 with homemade transverter 180mW, offset dish 60cm, only portable /P

QRP home-made:

I like building my own equipment, especially small QRP transceivers. At the moment I have several homemade TRX, but one is very special to me: my 30m 'Ozon' mintbox QRP transceiver, it measures only 5 x 4,5 cm! Power out is 700mW.

It's a superhet transceiver with VXO running from 10.104-10.111 and 10.114-10.131MHz (2 XTALs). And yes, it's a bit ugly, 85% is SMD parts, fortunately I have a steady hand and still good eyes! Right in the middle is the knob for tuning the band, when touching it, you hear the frequency change due to hand capacitance. However, when not touching the knob, the frequency is as solid as a rock!
The design is from DL2YEO (GM47 design, see http://www.qrp4u.de/docs/en/30m_trx/index.htm).
Sofar, all Europe has been worked with this tiny transceiver and even VE, A4 and CX!! It's a pleasure to listen to the nice audio and it is really incredible what you can work with such a small rig when condx are good.

Here is a picture of a complete set-up with VSWR meter, CW-touchkeyer and QRP-ATU, all home made:
















I am QRV from Peru from 15 jan 2015 until 15 feb 2015 as OA4/PA3GFE, QTH Lima, grid FH17KW. Activity 40-10m CW, SSB, Digimodes.
Rig: FT817 QRP 5W, Antenna: Vertical dipole for 30m and up. QSL via Buro, LoTW and direct (pse NO IRC's!).
Apologies if I could not hear you, at times the QRM levels are very high in Lima, especially on the lower bands.
