Arrow antenna
by Philip Jenkins 18 May '16

18 May '16

My 15 year old (or more) Arrow antenna has seen better days. Elements are faded, some are a bit bent, last director element on 440 is missing, coax and connector have been exposed to water briefly at various times, etc. I have the version with the built-in duplexer. I've always used it handheld (but now that I know that there's a mounting bracket for it, that could change) and until I got an email from Patrick WD9EWK a few minutes ago about another topic, I didn't know that the Arrow was being used for linear sats :-) So I'm looking to replace it, probably with the same model. I have considered the Alaska model, but I remember reading comments about how heavy it gets with handheld use. And I'm in EM85 (western NC) so that model is most likely excessive to my needs. And I could use it for linear birds, although the M^2 2M-440XP I already have is probably better for that. I've never used an Elk, though, so I'm considering that as well. One question I've had is how different this antenna might be since both sets of elements are in the same plane, as opposed to the Arrow with 90 deg offset. Is there really much ascertainable difference in operating between the Arrow and the Elk? Okay, I think I've tied up the BB enough for one day :-) Philip N4HF

HyGain DB218SAT baluns/CP switches
by Philip Jenkins 18 May '16

18 May '16

I've had this antenna system for about 8 years, and have used it very little, so I took it down a few days ago. http://www.hy-gain.com/Product.php?productid=DB-218SAT I had never run power to the CP switches, but I noticed the insulation on the power leads on BOTH balun assemblies have almost completely disintegrated. The outputs - one for RHCP, one for LHCP - where the cylindrical baluns themselves connect to the driven elements have lost their protective coating. My question is - are there compatible baluns and/or CP switches from other manufacturers which are compatible with these antennas? (HyGain sells them, of course) The CP capability doesn't matter as much to me since there aren't any HEOs like AO 13 or AO 40 in the pipeline (but please tell me I'm wrong if I am :-) ) (An aside - I'm thinking about selling these antennas as is, since they are - and were - overkill for my needs (since, again, there are no V/U or U/V HEOs which are feasible at this time) and using the proceeds to purchase the M^2 LEO pack) Philip N4HF

FT-736R 1.2GHz Issue?
by Christopher Maness 18 May '16

18 May '16

I have a fully equipped FT-736R. The other module works in the radio. There is white noise (sounds like it is working) on 1.2GHz, but it does not receive or transmit on this band. Is there a common known issue with this module failing in such a way? Any tips would be appreciated. Thanks, Chris KQ6UP

1.2 ghz module
by jeffory broughton 18 May '16

Start by removing the module, visually inspect every pin on every connector.clean every connector,reinstall the module and see what happens. Ideally it would be great to have a Second 736 to swap it out to see if it's the radio or the module. jeff broughton
