VHF NFD 2019

I entered VHF NFD as a "Sweeper" as usual, almost all operation was search & pounce or skeds set up via ON4KST.

Conditions on 70MHz seemed quite good, with strong signals from the GM stations, as usual some of the UK portables were hiding their light under a bushel so proved rather elusive. The only Es heard were the OY and TF beacons. I was on the band at various times through a 3 hour period on Sunday morning.

Conditions on 144MHz didnít match last year. I worked SN7L in the guise of SO3Z on Friday evening, but just heard short and rather weak aircraft reflections from them during the contest. Solar panel noise is very bad to the East so I operated mainly after dark on Saturday, and then looking around the UK on Sunday.

Activity on 432MHz seemed rather poor, with lots of empty spaces on the band. Best DX was by aircraft scatter with OK2A and DM5D. The SSPA failed on Sunday morning, when checked out the following day the series switching MOSFET in the 48V drain supply had fried, due to thermal runaway, so an uprated design is needed.

On 23cm the best DX was again OK2A and DM5D by aircraft scatter. DM5D was also worked on 13cm, and copied well on 9cm, but a two way on this band was not to be. Other good QSOs on 13cm included DJ5AR and DL3IAS in JN49. This contest was the first outing for a new 23cm SSPA using a single PRF13750 device (W6PQL) and it worked well.
