DX-QSO's are reachable also with a QRP station. That show the number of DXCC entities achieved so far from me. Of with bracket indicated entities are present unfortunately still no QSL cards.
 
3A, 3B8, 3V, (3X), 4K, 4L, 4O, (4Uitu), 4X, 5A, 5B, (5N), 5X, 6Y, 8P, 9A, 9G, 9H, 9K, 9M2, A4, A6, A7, BV, CE9, CN, CO, CT, CT3, CU, CY9, D4, DL, DU, E4, E7, EA, EA6, EA8, EA9, EI, EK, (EP), ER, ES, EU, EX, EY, EZ, F, FM, FP, FR, FS, G, GD, GI, GJ, GM, GU, GW, HA, HB0, HB9, HC8, HL, HP, HS, HZ, I, IS, (J2), J3, (J5), J7, JA, JT, JW, JX, JY, (KH2), KL, (KP2), LA, LU, LX, LY, LZ, OD, OE, OH, OH0, OJ0, OK, OM, ON, OX, OY, OZ, P4, PA, PJ2, PY, PY0F, R1m, RA2, RAas, RAeu, S5, S9, SM, SP, ST, SU, SV, SV5, SV9, T7, TA, TF, TK, TU, TZ, UK, UN, UR, V2, V4, V5, VE, VK, VP2m, VP5, (VQ9), VS6, VU, W, XT, (XU), YA, YB, YI, YL, YO, YU, YV, Z3, ZA, ZB2, ZC4, ZL, ZS
 

 
There are at the time entries on the list of DXCC Entities. This is a great pile of entities to reach for me as QRPer, until I could retire from DXing. ;o)) But there are also stages on the way to the DXers heaven. One example: For the well-known 5-band DXCC-award (5BDXCC) 100 confirmed QSO's are necessary on each of the classical 5 short-wave bands. At the time I need only QSL cards of the necessary 500 cards. And in finitely time it should be possible to reach the missing QSO's, also if I am not as full time DXer.
 
If you see, also for QRPers is nothing impossible!
