[PSUBS-MAILIST] radio's

Sat Mar 29 16:06:35 EDT 2014

Hank, Scott,

You might want to look at ultra shortbase tracking for the sub. Good systems can be had for $15K. And, as Scott discussed, sonar is also a function of exponential dollars. If you want to stay in the low thousands, then you settle for shorter range and less definition. After that, it's a step up to the big boys at $30K or better. A decent boat sonar can be used in conjunction with a good tracker and a dependable UQC to vector the sub in general toward targets, but to do both on both ends gets pretty expensive. Hank could well double his investment just in electronics, and Scott would be just about tripling his. Moving beyond line-of-sight in the water is expensive, no doubt. Very useful, but painful to the pocketbook. Hank's EDO comm units are UQCs, not radios. The Q is Navy-speak for acoustic, as in underwater acoustic communications. They don't work like radio, of course, in that the signal is converted to acoustic on the send/receive end. Which explains why radio antennas cost fifty bucks and transducers like Gamma's cost thousands upon thousands.

Just remember with these sonars the downward imaging gets less and less sharp the further down you go. After about 150' it really falls off and the image is super small. The sonar beam is a cone shape (I believe like 9 degrees on the downward imagine part). The only way I know of to get good side imaginig from a surface boat in water deeper than 150' is a tow behind and they start at $10,000. If it is on the sub, it is a cheap way to get good imaging. If you wanna get really awesome imaging, get a blue veiw. But they start at $30,000.
Thanks,
Scott Waters

Hi Scott,
I will need help,lol,  I am actually thinking about keeping the sonar in the tender.  So my partner and I can search for a site and he can keep track of me in the sub as well as talk to me.  I have a real sweet 14 foot alum boat with 35hp it is all old but rock solid.  So I will start looking at the Hummingbird then.  I will need 500 foot range though.

I would personally stay away from Lowrance. For them to do side scan imaging, you have to buy another modual and it is bulky. The humminbird is all slef contained. I honestly wanted the Lowrance at first cause I liked the sound of the name better, haha, kinda dumb reason, but when I started to research them, I decided on humminbird. I personally chose the 898c because of it's capabilities. I would of liked to go to the 1000 series, but the screen is just to big for the inside of my sub. I believe euronaut also has a humminbird 898c as well. If you decide to go that route, be sure you get the right subcon connector. You have to remember the GPS module has to be ran outside the sub as well and must be epoxy filled. I can help you through all that if you need. I made alot of mistakes connecting data wires that could be easily avoided.
Thanks,

Scott,
Thanks' for the info, but I am going ahead with repairing my radio's.  I am also looking at buying a sonar now.  It's all your fault,lol.  I gotta have one, what would be your first choice?  I am looking at a Lorance HDS-7

Seems like it would be nice to have one of those 70 watt units for the sub !

Hank,
There is currently a surface station and a aqua comm which is what I used in my sub for sale for $1500 for the two ($750 each). Most psubs members that have underwater comms have OTS so his would be compatible. Here is a link about the hummin bird 898 and it shows how to read the images you would see. I will post images after I test. it will be fun to see how they compare.

Scott,
I would love to see some pictures of the image you get on your sonar.  When you start testing could you post some pic's .

Here is the link Hank. Great deals on underwater comms. This is where I got mine for my sub and surface unit.

Scott,
I agree, but I am having a hard time finding anything on line.  The tec did say my radio's are better than today's radio's.  He was probably giving me a sales job though.

Oh wow. Ok. I was going to say if it was OTS you can send it in for repair. You might check the range and quaility of the radio so you can make a decision if repairing makes sence or if it would be better to buy new units (or used). Alot of times newer technology is better and less expensive especially when it comes to repair. That way you can get the biggest bang for your buck. 
Thanks,

I found some info on the radio's, seems they are the original radio's.  Manufactured by EDO Corporation.  They were refurbished in 1992

Scott,
I got the quote from a electronic repair shop.  The radio's are not OTS, I can not remember the name off hand and all the manuals etc are at their shop now.  The radio's are made for submarines, they are not diver radio's.  The radio's are rack mount and they were even labeled with Nekton Gamma on them.

Who did you say gave you the quote? Is this OTS brand?

Steve,
The radio's do not work completely now.  The pinger works and one frequency works only.  They are cleaning up the corrosion and re-sealing them and they claim the radio's will work perfect as new.

Hi Hank, I was just curious if you had more specifics regarding "rebuild". What is in that scope? Do they work now?

Hi All,
I need radio advice.  My technician tells me, he can rebuild my radio's to as new condition for 2,000 dollars.  He has checked them out and says they are very good radio's and the transducers are perfect.  The radio's have a 1,000 foot depth rating and 6 km range according to the manual.   I am assuming this is much better than buying new radio's.  I have no idea what these are worth and I want to make sure I am not fixing radio's that I can replace for the same money.  
I would appreciate some advice before I pull the trigger and tell them to fix the radio's.
Hank
