- Subject: 10 GHz EME question
- To: info-hams@ucsd.edu
-
- The Toronto VHF Society (VE3ONT) is beginning to make
- plans for EME operations using the 46 m (150') dish at
- Algonquin Park later this year.
-
- We have been discussing the possibility of trying EME on
- 10 GHz. The dish is figured to at least 12 GHz, and is
- adequately steerable. The question is this: is there any
- point to using such a big dish at 10 GHz for EME? One
- argument says "yes, the gain will be humungous." Another
- argument says "no, the high gain of the dish will under-
- illuminate the Moon so there is no *real* monster gain."
-
- I subscribe to the latter point of view. It seems to me that
- an antenna beamwidth of < the Moon's diameter doesn't benefit
- the overall link budget. By this argument, 10GHz EME is
- optimum with a dish about 4m in diameter (beamwidth about 0.5
- degrees, the apparent width of the Moon). The 46 m dish will be
- no better than a 4 m dish.
-
- So... am I correct?

- Well, you'll need a reciprocal permit - I'd suggest you ask the ARRL for their
- RECIPOP package for the UK, and count on the process taking a number of weeks.
-
- As for frequencies, the 2M band here is 144-146MHz, with the bulk of the FM
- activity in the upper MHz. Repeaters are all 600KHz split, with the outputs
- high. Channel spacing is 25KHz. If you need anything more specific, let me

- In favour of the no-confidence vote 198
- against 72
- invalid votes 4

- Results of QSLing.
- Yes, it does get results when one sends a QSL card
- direct with a suitable green stamp enclosed.
-
- Today, 10th March 1994, VK2BQS opened his mail box to
- find a card from USA, not unusual we agree... The card was
- from a well known QSL Manager and was posted 24th Feb 1994.
- Still not unusual.
-
- It was for a QSO with ANGUILLA, now that is unusual as
- BQS did not recall the contact and felt sure it was a new
- country.
- Wait, it shows a 2XSSB contact and it seems a long
- time since anything other than RTTY has been QSLed. But it
- does say TNX for QSL.
-
- Oh boy, the date of QSO ... 11-1-79...Fifteen years?????
-
- Dig out the log book (number one) and woe, nothing
- under 11th January 1979, thinks???? (like greenbottle). Dig
- again, for log book number two, and there on 1st Nov 1979 is
- VP2EY and lo and behold, the QSL went direct with a green
- stamp or equivalent, and this is the first reply.
- And a check of other records shows that was the only
- time VP2E was worked in 17 years.

- AINT PATIENCE WUNNERFUL..

- Due to a recent policy change from Software Tool and Die's
- Internet computer system, the World, the ham radio archives from
- World have moved to the very well-known anonymous FTP site of
- oak.oakland.edu (141.210.10.117).
-
- The directory on Oakland where the files will be locate will remain:
- /pub/hamradio.
-
- The Oakland FTP site permits a maximum of 400 simultaneous
- anonymous FTP connections, so there should be plenty of space for
- everyone to access what they want, when they want.
-
- The directory structure on Oakland will remain the same as it was
- on World.

- I don't know how good or bad the 830's noise blanker is, but a general
- answer to your question "isn't that the kind of noise..." is that
- blankers work best on the noise that's the most dissimilar to a
- signal. High amplitude, short duration noise, aka impulse noise, is
- the easiest for circuitry to distinguish and eliminate. On the other
- hand, any noise that's in the audio band and is roughly the same
- amplitude as the desired signal is impossible for normal circuitry to
- remove. I know DSP can help here, but I don't know enough about it to
- say how effective it is.

-
- My club has been kicking this around for way too long now.
-
- We have looked at several PC-based repeater controllers,
- but they are either way the hell too expensive for
- what they do or they do only what they do with no
- room for innovation or expansion.
-
- Both issues gave us pause. I wouldn't mind developing
- a neat driver that would allow you to write your
- own repeater controller in a script language, but
- that sounds too much like work if there was no $$$ market
- for it. Similar sentiments have been expressed to me
- by an associate who wrote a microcontroller repeater
- controller.
-
- So, is a whiz-bang system meeting my wish list
- above now available in the ham market?

- Hey, who ya talkin' about, Bob? AH6FU is a Hawaii call, and there's only
- one Hawaii ham who posts on here.... (oh my God - is he referring to me?)
-
- I guess Hawaii hams will be vying for 2x0 callsigns since we have to
- have the mandatory `H6' in the prefix. Not much of a choice:
- AH6, KH6, NH6, WH6. Phooey. [Hey, now there's a neat call: PH0OEY.]
