Mud and Hamfests go together in central Ohio. I lived within a day trip of Dayton Hamfest from end of 90's to start of 2000's. Why did Hamfest go to shopping center parking; to many cars getting stuck in the nearby on grass parking. So Hara even when it was semi-good had the mud problem.

Those of us that parked at the old Salem Mall had no issues with mud.

This discussion could go terribly wrong if we are not careful...  Smiley

Wow, that is a chip from the early '70's; also look for the Plessy SP613, it was the progenitor of the 11C05.

Even back then it was a $50 chip

........1.2G standard?  Why?  It's an insanely difficult band to use.  You need coax the size of your forearm......


This is the exact reason that I think for at least terrestrial point to point contacts, transverters are superior.  You can place them along with an amplifier in a NEMA enclosure at the tower base, or even closer to the antenna, and use a lower loss 28MHz. IF back to the operating location.  I'm looking forward to seeing it at Hamvention in a few weeks, but I don't ever see it on my desk.

Hi Guys,

I did some research, not seeing much so decided to seek advice from you experts here. I would like to know what you would recommend for a a 2M, 70CM and 118-136 Mhz (Air traffic) RX mobile antenna please.
I have a Diamond  Dual band 2m and 70cm nr72bnmo and love the size, performance and durability of it, but would like to be able to listen to aircraft frequencies too.

I think my antenna will receive 118-136 Mhz but would like to have as close to optimum for HAM and Aircraft, what would you guys suggest. I have an Alinco 635T but would like to replace it with the 735T.

Thanks so much guys.

I would suggest a simple 2m 1/4 wave whip. Reason being while it would have marginal performance on 70cm (due to higher radiation angle of main lobe on a 2m 1/4 wave acting as a 3/4 wave on 70 cm) it will hear pretty good on aircraft band. Reason being that a low gain 1/4 wave has a wider bandwidth on reception than a tuned antenna with a higher gain.

Does anyone have any experience with these?  I haven't been able to track down much in the way of firsthand reports and feedback from owners but I have to admit I'm very inclined to get one.  HRO has them available which brings some comfort if it doesn't add up to what I expect.  That said, the limited information I've found seems to be positive.  They aren't terribly cheap, but they have a lot of functionality packed into such a compact (portable!) form factor.

I have one. Nice, little unit. Make sure to use with a good antenna, as the power output is low compared to using some of the Byonics trackers or the APRS-ready HTs from Kenwood and Yaesu. Having some good APRS infrastructure around you will help with the little radio.

73!

I got the bill on repairing brake line 125.00. Looks like the radio is going to happen some time in May. Everyone have a SAFE Day..73s

Yup I have heard folks talking and will not respond when I ask to join in- It's like AA4HA said it's the Beta/VHS thing all over again - and since I know no one even with all these repeaters- pretty lonely and yet I know there are hams all around as I can hear them on other "nets" checking in- I will remain hopeful and I'll still keep on CQing / asking for a ragchew / and see where it goes -  Will keep ya'll posted

Drat! I was going to say that you might have more fun if you were working SSB on 2 meters but I do not know what type of radio you have, So many of the 2/440 rigs are FM only.

SSB on 2 meters can be really interesting, you can also try for satellite ops, at least with satellites those folks do want to talk. You can work satellites without crazy antennas, sometime even a tape-measure yagi mounted on a wooden stick can get in to a satellite.

I have a couple of FM HT's but I only listen to them during severe weather or to periodically check in on net-night. If I do a long distance trip I will use the radio on the car and try to pop up on repeaters along the way.

And, let's not forget that some of these DX stations have hidden expenses we don't.  It is depressingly common on some of these little islands for imported goods, especially tech goods, to have ridiculously high tarriffs on them.  That's right, a lot of countries view ham radio rigs as a "luxury" item and tax them accordingly (I leaned this when DXpeditioning -- once, I had to carefully declare and register my gear, by serial number, and show the customs officials that I was indeed taking it back out when I left).  In another, I had to pay what amounted to a fee to bring my gear in even temporarily.  It was not a triffling sum.


 I brought along an Alpha 99 & Yaesu 1000D to St. Helena island back in 2007. Everything coming ashore was gone over with a fine tooth comb by St. Helena Revenue especially any electronic goods. Imagine my surprise when they hit these items with a $2,100 "import tax". It didn't matter I would be removing the items from the island after the DXpedition was over. My equipment was held under lock & key until I paid the tax man................Shakespeare was right regarding his famous quote regarding death and taxes.

 Anyone who thinks single person DXpeditions even come close to breaking even need to go DXing for themselves & see.
