GW3UEP 630m Transmitter Tweaks
![]() |
| DF8UO's GW3UEP 630m Tx |
From Daniel's test data, it looks as though the IRF540's are quite happy as long as you keep the transmitter at 100W or less ... anything higher would certainly benefit from the switch to IRF630's as the high efficiency is maintained at least to the 300W level. Something at this level would no doubt benefit from higher-voltage capacitors and heavier inductors as well as a little more heatsinking, enough to shed at least 25 watts of heat between the two FETs.
Daniel drives his amplifier with an Ultimate3, followed by a 10db attenuator, a squarer and into the totem pole driver stage. His own version uses toroidal inductors rather than the original air wound coils.
A pair of GW3UEP amplifiers using IRF630's at ~40V into a small power combiner, should provide ~550W of useful output at >90% efficiency ... more than enough power to do some serious work on 630m.

Guys who build stuff
Jim was putting out all of about 2 Watts to his antenna, but it was enough to garner him a 569 report from me. His signal was a little chirpy and a tiny bit raspy, but it was still pleasant to listen to and fully copyable. Shortly after our QSO, Jim e-mailed me the above photo. I know how satisfying it is to build a kit and have it work. I can only imagine how much more satisfying it must be to build something from scratch and have it work. I'm not the greatest scratch builder, but the few times I have and have had the finished product work were enough to make the ol' shirt buttons pop.
Another friend who is into building from scratch is my good buddy, Bob W3BBO from Erie, PA. As mentioned before, Bob is my Ham Radio mentor, and I've learned so much from him that I don't even know where to begin. Here are some photos of a series of regen receivers that he's been homebrewing.
Now does he do nice work, or what? Very nice work, indeed! I know that Bob has been conversing with Dave AA7EE, who's listed on the blog roll to the right. As far as I'm concerned, Dave's one of the Master Builders. His creations come out looking so good as to be museum pieces, in my humble opinion.
I wish I had an nth of the talent that these guys have. My creations always seem to come out looking more like something Dr. Frankenstein would have created. Functional, maybe, but definitely not pleasant to look at.
This afternoon, I worked three more NPOTA stations:
AC9FL - SSB - TR55 - Ice Age National Scientific Reserve
N4MJ - CW - BF04 - Fort Donelson National Battlefield
KS4YT - SSB - NP30 - Hot Springs National Park
Sadly, my SSB pileup breaking skills are nowhere near my CW pileup breaking skills. It's going to be interesting to see if they improve as the year progresses.

New Year’s Day
I got on for a bit last night for SKN. I don't know if it was just bad band conditions with the remnants of that CME lingering; or perhaps it was my atrocious bug fist. I made no contacts last night.
During the day today, I did a bit better. I worked five different NPOTA activations (6 QSOs):
N8XX - TR04 - North County National Scenic Trail
W1BXY - NS76 - Weir Farm National Historic Sight
NC8IN - NS55 - Ninety Six National Historic Sight
NR3P - SS01 - Assateague Island National Seashore
KK4ZUU - BP02 - Mnasassas National Battlefield Park
K7UPJ - NS55- Ninety Six National Historic Sight
I just realized now that I worked NS55 twice. Basically, I was dial twiddling, working the ones I could hear decently. There were a few others, but QSB was so bad on 20 Meters at times that I bypassed a few, thinking conditions would get better. They didn't, and going back to try and work those again, I found them to be gone. Sometimes the Propagation Princess is a cruel mistress!
Only N8XX and NR3P were CW, though. I had to break out the microphone and resort to SSB for the others. As Yoda would say, "A disturbing trend in The Force, I sense".
As mentioned in an earlier post, the 2016 NJQRP Skeeter Hunt will be featuring NPOTA - but let that be just a foot note. I would hope that a lot of you who read this blog regularly will step up the plate and activate NPOTA entities using CW (and QRP).
Remember, it doesn't have to be an elaborate set up, with multi ops and crazy antenna installations that last all day. This NPOTA program was tailor made for portable QRP ops! Go to one of the entities, throw a wire into a tree, or perhaps break out the Buddistick, Buddipole, Alex Loop - what have you. Get on the air for a few hours and hand out some contacts!
Also, remember that this is a year long celebration. There were a bumper crop of NPOTA activations on the air today. It seems that everyone wanted to be active on "Day One", but there are 365 days left (this is a Leap Year, don't forget). So get out there and have some fun. That's what this is all about - going outdoors, setting up and having some fun.
This is OUR specialty, guys! Let's show them how it's done!
