14.345, 10 AM ET SATURDAYS, AFTER VARO NET SUNDAYS:
HA5SHF reports 23 cm QSOs in June with VE1ALQ and EA6ADW.
W5LUA QSO'd RW3BP again on 6 cm. On 23 cm Al worked OZ6OL for a new one.
K2DH blew up his 23 cm PA during the June SW. He replaced a bad tube but needed to fix the bias circuit. Dave worked OZ6OL with just 60 w.
W7CNK on 432 worked JA2TY, VE1ALQ, DF3RU and OK1KIR in June. He heard nil during a sked with S52CW and HP3XUG and did not complete with PY5ZBU (no R's).
KL7HFQ heard nil from SV1BTR and W5ZN. He changed receive feedline to 1/2" Heliax and saw a big improvement.
K9ZZH is looking for 1296 skeds.
W7QX worked on 432 IK2IAD, DF3RU and OK1KIR. Heard were W7CNK and KA0RYT.
KB3PD will be off 70 cm for while. No skeds please. Rick burnt up a 7/8" connector.
WD5AGO is taking his 23 cm feed out and will concentrate on 70 cm through Sept.
OZ9AAR's logs and QSLs were lost during a recent move. Carsten asks that anyone that worked him on 23 cm to please send another QSL card and pictures if possible! He is very upset by this loss.
I5TDJ, Pierro worked on random W7CNK for initial #107.
LZ2US is getting back on 70 cm EME.
G0RUZ has moved QTH and is coming back on 23 cm EME.
PA3CSG worked AA5C on 10 GHz and will run with NU7Z and VE4MA when they are ready.
VO1AV Ron has 70 cm xvtr and other stuff to put together an EME station, but still needs to work on antennas.
VE4MA had some success with his 10 GHz TWTA (75watt tube) and is just about ready to go.
DL9KR has just returned from a 6 day trip to the US.
W4TJ is still plugging away at 23 cm.
K5JL heard nil from OE3JPC on 23 cm, but did work him on 70 cm.
K3HZO worked on 23 cm in June W2UHI, N6BQ and K5JL, heard several other stations, and had a partial with DD1XF (O/-). He will be QRT in July.
EA3UM has been doing a lot of business travel and as a result missed his May skeds with SB1BTR and W0GGM. Magi is still very much QRV and interested in skeds.
OE9XXI has cavities for TH327/347 (with blower and heater
transformer) and TH308/328 available. Both cavities are
commercial designs modified for 1296 operation. Contact Peter

Thanks again to G4RGK for his help with the NETNEWS
section of this NL. I gave Dave very little warning due to
business travel during the past week. I should also express
my thanks to Joe, K1RQG, who besides running the 20 m net
also records the Netnotes from which the NETNEWS in
condensed. (I can take advantage of Joe as he is an old
friend.)
Does anyone have any information on Cor, VE7BBG? Cor was the
original Skeds Coordinator for the NL. He has been receiving
the NL from the start, but his envelopes have come back
undelivered the past 2 months.
This was not a great day for producing the NL as I lost a
sizable portion of the NL text - something I have not done
(mercifully) for some years. The NL would have been longer
and included the full text of Steve's review, if not for this
loss. At least the NL should arrive on time.
I expect to get the Aug NL out just before I leave for Eur
and the Paris EME Conference. I am not sure how I will handle
the Sept NL as I plan to spend almost 3 weeks in Eur. I will
work something out. Please keep the info coming. I hope to
see all of you in Paris and off the the Moon during the July
SW.

SSB Receive audio sounds great Collins filters are optional

filter.

such as 222 and 1296 MHz.

DSP filter bandwidth is very good. DSP filter has VERY poor shape
factor.
CW keyer built in. Keyer is not a memory keyer.
Fast / Slow Tuning selection button. Sense is backwards, I would prefer
it to default to fast and slow is selected.
Also, fast button effects to many
items such as band switching are effected
simultaneously by the FAST button.
Should be able to program what functions
the FAST button changes.
Pleasing front panel styling. The FT-847 is just too plain small
for a home station, Give me a
FT-920 size radio with coverage
through 450 MHz (1300 MHz?) with
good DSP and a memory keyer. Requiring
external antenna tuners and memory
keyers defeats any advantages the
FT-847's small size has. The knobs are
too small and close together.
Separate amp switching circuits Uses hard to find 5 pin mini DIN

40 VDC rating for safety factor.
