[600MRG] 630M QSOs tonight

[Eric NO3M]

Good batch of QSOs this evening on 630M.  Started with WH2XGP on JT9-1; 
QSO took a few cycles longer due to RX QSB on my end.  Around 0510z, CW 
QSO with WG2XIQ, good sigs and ragchew; WH2XHY broke in as we were 
signing off for a brief three-way exchange.

Ran the new breadboarded MOPA rig bareboot on CW this evening; 809 
Hartley osc driving push-pull 811s 
(http://no3m.net/index.php?page=630m-mopa).  Reports were positive on 
stability and note characteristics.  Still considering adding an 807 
buffer stage between osc and amp (per circuit found in old RCA Ham Tips, 
Vol 1/No 1 Sept '38 and Vol 2/No 5 Oct '39) to eliminate some effects 
(amp grid tuning changes) on osc freq and note.  May also try an 807 or 
other tube in the oscillator as an ECO (electron coupled osc) Hartley to 
further reduce upstream tuning effects on osc.

Fun stuff.
