Although there may be some disagreement, I believe most 70 cm stations found conditions to be rather poor. It must have been especially difficult for fixed pol yagi stations. For much of the contest I had to rotate polarization between TX and RX by 90 degs to be heard. Fadding and overall signal quality made copy a challenge without the added ingrediant of QRM. Things were somewhat better on the higher bands with increased activity on 13 and 3 cm during the weekend.
I wish to expess my thanks to all those who have made 2424 receivers for listening to JA on 13 cm! My final contest score was 2 on 144, 18 on 432, 27 on 1296 and 5 on 13 cm.
-1- He want's to make it clear that he is not suggesting any changes to the contest.
-2- Any suggested changes to the contest should be clearly thought out as to what their effect will be on world wide EME activity before they are passed on to the ARRL. Specifically consider the following:
-A- If the objective of the proposed change is to alter the scoring such that a U.S. station will win the contest, it is unlikely to work. The top Eur stations make more QSOs than do stateside stations. Adding more multipliers will end up increasing the point difference as it is likely that the big European guns will still work all the available multipliers.
-B- The introduction of states as multipliers will require the use of their QTH in the contest exchange as is done in the VHF contests. It has been suggested that EMEers know where everyone is located or they can use a cheat sheet to find out the contest multipliers. This will discourage new EME stations to enter the contest, and especially discourage them from sending their logs as how will a new station know who and where everyone is. I maintain my own database of 432 MHz EME stations which I update almost every week when I listen in to the 20 m net and I can't keep track of every call and where they are. I also do not believe that a legitimate contest QSO is made when you have to look up the multiplier instead of receive it over the air. Adding a report to the exchange will also make it more difficult to work the weak ones. In addition stations may be chasing initials and will not be interested in making a contest exchange.
-C- The purported objective of the change is to get the Eur stations to stay on longer so they work more multipliers which will come from rare western U.S. states. The serious Eur EME contesters already stay on virtually to their moon set, so nothing will change with them. The casual European operators simply will not stay on longer because they are not serious about the contest and hence they will not care if they pick up a couple more multipliers and still will not have a reason to stay up.
-D- If U.S. states or ARRL sections are counted as multipliers than is there a reason why the Australian provinces, Russian Oblasts or provinces and states from any other country in the world should not also be counted as multipliers? Why not go all the way to WW grid squares. Where do you draw the line?
-E- If the objective is to get the Europeans to stay on longer there are two ways to accomplish this.
A) Get more US stations QRV, especially from the western states so there will be a reason for them to stay on.
B) Run DX expeditions to the western U.S. states during the contest so operators interested in new states or new initials will have a real reason to stay on. Although this dissertation may sound like I'm opposed to the change, in reality I'm not offering an opinion at this time. What I am trying to say is "Before you amputate the patient's foot, make sure the real problem is not that the patient has a sore throat!"
70 cm EME totals for K1FO are: #512 initials, 49 states and 75 DXCC.
EA2LY is in new grid (IN93). He was in grid (IN80) for the 1997 DUBUS Contest. So QSOs are initials if you worked before 1996. When in IN80 he may have used EA4LY or EA2LY/EA4.
F5SDD and F1IKA appear to be the same station. F5SDD is running 8 x 26 BV yagis, TH6007 PA at 600 w and MGF 1302 (.45 dB) LNA. His e-mail address is F5SDD or F1IKA
VE1ALQ added initials on 23 cm with JH5LUZ and W4OP, and 1 on 70 cm JA3IAF. Darrell scored in the contest 36x? on 432.
LX1DB was not on 6 cm in April due to el drive problems, but is now QRV. W0AH reports 13 contacts on 70 cm in the contest.
VE6TA on 70 cm scored 17x14.

NU7Z added W7GBI and WA8ZWG on 13 cm to bring him to #8 initials in 4 startes and 5 countries.
WI7Z worked 15 stations and 2 initials to bring him to #39. He CWNR F6CGJ many times.
KA0RYT scored 28x19 on 432 in the contest with 4 initials: ON4KNG #57, F6CGJ #58, JR9NWC #69 and ? #70.
K7XD is a new station with 4 yagis and 600 w. Derek is hearing stations. He can be reached at 360-573-9673 and is interested in skeds.
KL7HFQ worked on 432 in the contest K4QI, OH2PO, K1FO and JH5OVU.
KF0M was not QRV in April because of business travel and probably will not be QRV again until after mid May.
W4HHK worked on 13 April on 13 cm WB5LUA (O/O), WA8WZG (M/O) for initial #36 and a new state and F1ANH (O/O).
WA7TZY was active in the contest with 8 x F9FT yagis and 1200 W+. He does not want any skeds and operates on random only.
F6CGJ reports contest scores of on 23 cm 59x33 and on 70 cm of 32x21. Louis may be QRV on 10 GHz for the next SW. He says the '98 conference will most likely be in Aug not Sept.
UR5LX ended with 60x37 in the contest with 3 new stations: F5AQC, JA0VI and VE4MA.
UR3EP, Vladimir made initial QSOs with OH2PO and K5GW in the contest. He is finishing a new 600 w final.
DK3WG has repaired his station and is QRV on 70 cm again. He added initials with JA3IAF, JJ1NNJ and F5AQC to bring him to #332. Jurgin needs QSL cards from N6OVP, WA8WZG, K5GW, N4UK, WI7Z and WB6IMC.
UT5EC scored 25x? in the contest with 10 new stations: 7M2PDT, KA0RYT, F5AQC, K5GW, EA8FF, K4QI, EA6ADW, G3LTF, JH0YSI and PA2CHR to bring him to #91.
W7CI worked 7M2PDT on random. Steve will not be QRV for the May SW.
W4AD (ex-K4HWG) has a 10' dish and is working on 3 cm EME.
W5ZN (AK) is working on a 432 array, and hopes to be operational on 70 cm EME by the end of June. He is also still working on 5760 EME, but has not yet make a contact. He needs to improve his Az/El control.
EA6ADW's e-mail address is EA6ADW
PA3CSG will not be on during the May SW.
G4RGK worked 10 with 200 w and 4 yagis during the contest.
DL1HTT is a new 4 yagis station.
DF6NA, Rainer now has new high power 1296 MHz amps available. He is offering some semi-professional HPAs for 1296 for serious DX-work like EME. The small model uses a YL 1050 and is based on the DUBUS article by DL9EBL. It will produce up to 1.5 kW output. The high-end model uses a Thomson TH 327. Test results with a prototype cavity yielded 2,240 w at 2.55 kV and > 3 kW at 3.5 kV. Efficiency is > 40 % with a gain of about 8 dB. (Max Heater current is 30 A and must be limited for about 5 sec.) Cavity length is about 20". The YL 1050 cavity is priced at US$1,300 and the YL 1050 is US$400. The TH 327 cavity is US $2,000 and TH 327 is US $500. Also available at the moment are two TH 308s for US $350 (each). There is also a chance to get some more TH 308s in the near future. All prices "ex work" (+ fright/insurance). Please reply to Rainer, DF6FA

K9ZZH is looking for info on the old RCA 6161 tube. He has several tubes and a cavity and wants to know if it is worth putting it on the air? [As I remember it, you can get a little more out than a glass 2C39. I would put my effort in water cooled 7289s.].
W4AD (ex-K4HWG) is looking for TWTA for 10 GHz.
K1FO, Steve has parts remaining to build only (3) LA-70B, 70 cm, (3) LA-135, 135 cm and (3) LA-200, 2m Lunar-Link Systems amplifiers. He is sold out of PS-70 power supplies. Parts have been ordered for another production run of power supplies which will again be shipping in June.
There is some bad news, however; Alan Greenspan (the chairman of the U.S. Federal Reserve Board, who has raised interest rates to slow the US economy) must be on to something in that after several years of near constant prices, inflation is back. The custom sheet metal for the new batch of PS-70 power supplies has increased in cost by over 10%. Worse than that, some of the components, such as wire wound resistors have gone up over 20%, and the most expensive part in the power supply, the transformer, has increased by 5% earlier this year, and will increase by another 10% in a few months. What all this means is that the price of the PS-70's is going up. Steve is planning to make another production run of LA-70B 70 cm and LA-200 2 m amplifiers, but prices on the new run of amplifiers will have to increase. Prices on the remaining amplifiers from the old run will stay the same until they are sold out. Contact Steve, K1FO at 203-421-3377.
K6LEW has purchased Rutland Arrays.
KB2AH has a full line of cavity amps and 1, 2, 4 and 6 tube ring amps, lin/circular feed horns and LNA's for 432 and 1296... And recently he has added mounting blocks for K1FO yagis. For full details see: Tom, KB2AH's 1296 WEB Page for price e-mail: Tom , or phone 908-223-5067, FAX 908-223-0901 (24 hrs) or voice 908-223-8124.
DD1XF has for sale 2 6 cm 11 w commercial SSPAs. He also has 2 6 cm triplate couplers and 1 6 cm W2IUM feed horn machined from Aluminum with an excellent match. Pick up only - call Frank at 0049-40-642-82-53.
DL8RDI has 23 cm 800 w cavity amplifiers for sale. These cavities work with TH 328 and TH 338 (60 w drive) tubes and require about 2100 V at 1 amp. All amps are brandnew and polished. Contact Heiner at (H. Jordan, Nelkenstr. 26, D-93346 Ihrlerstein).
I have more sad news. Last month was not enough! Lin Holmes, W0MDL,
an EME pioneer and a regular on 432 from Minn back in the 80'ies has
joined the list of silent keys. Lin will be missed.
The 1296 band is under attack in the U.S. K2DH (an others as W2VVV) urges U.S. EMEers to write to ARRL and FCC to object to EDAP Technomed Prostatron machine use in USA on the 23 cm Band.. 60 w out and >100 kHz wide. There is 915 MHz machine in the states made by Uroligics. EDAP is using availble amateur equipment to keep its costs down. Copy to ARRL, EDAP and the FCC.
Read and Act on EDAP TECHNOMED, a Threat to 1296 MHz.
There was much debate during recent 20 m EME nets on possible changes to the ARRL contest rules. KB2AH has proposed to count U.S. states and Canadian provinces as contest multipliers. K1FO addresses some of the issues concerning this proposal in detail in his report. There has also been considerable discussion about polarity rotation, etc. on the net. With many more stations now having the ability to change polarazation, we are now seeing the problem of both stations rotating simultaneously. It is like a dog chasing his tail. Joe, K1RQG suggests that it is time to revisit 70 cm protocols.
Sorry but there is no time for more this month. Please keep the news and especially the technical reports coming. E-mail is the preferred way to submit information, but we will take reports in all forms.
CU off the Moon.
