Nicely done!

I was wrong about the signal width.  On the waterfall it looks to be about as wide as a normal signal.  But it is very clearly digital.

So.  Close examination gives me:
* sometimes signals are weak.  Sometimes the signal is surprisingly strong.  Hypothesis: I am seeing *different transmitters* on the same frequency.
* The signal looks like DSTAR on the waterfall.  It sounds like DSTAR when you listen on an analog FM receiver.

Aha.  These are the clues we need.

I go to repeaterbook.  I’m looking for a repeater with the INPUT frequency of 146.5, because I think I am hearing different transmitters transmitting TO the repeater.

Repeaterbook gives me this DSTAR listing: KF7CLD 147.5 -1MHz shift, located in Burien.

My conclusion is that we’re hearing DSTAR users working the KF7CLD 147.5 repeater in DSTAR mode.

Some of the time I hear a very faint CW tail after the digital portion of the transmission.  That really, really suggests it’s a VNBD amateur transmission of some sort, because I just can’t imagine some random signal terminating with a CW callsign ID.

Sadly, the CW id is too faint for me to copy.

I have two separate reports:

2.  In Carnation, HEAVY interference on 146.5, but it sounded like very loud static, with no modulation.  The interference stretched from 146.450 or so all the way up past 146.550, strongest at 146.51 or so.  As I drove from Carnation to my place, the strength of that interference faded.  I get about two bars at my house.

If someone could take a look at a panadapter when they hear the interference, well, it would be mighty nice to know how wide the different signals I heard are.

If it’s DMR or DSTAR then the bandwidth occupied is going to be narrow.  What I heard entering Carnation was really, really wide - 100KHz at least.  Or at least I could pick it up on my Kenwood D710G across a range that wide.

Re: Great Site

Rowland
 

As I have stated before it is very important to know how to manually program your rados.  Software is a great tool but when you do not have access to it and need to program a frequency or repeater manually (and that need will arise) it is better to at least have one of these short version cheat sheets with your radio HT all times.  I suggest printing them out, laminating them and then attach to the radio with string, rubber band or what have you.

Rowland

WA7TBP Tarhell gear

Tom WA7TBP
 

Hello all:

I have listed the Tarheel gear I use.

    My Ford Excursion. The Model 300A. Using the MT 1 Mount. I just use the manual switch for tuning. I have           found this works really well. I have nylon ties at the frequencies I use all the time. When you run the tune   
    switch, you can hear the antenna when it arrives at a resonant point.

    In my RV's, I use the Model 75A. I use the MT 3 mount. I make sure the mount is well grounded to the vehicle,      using 1 in wide braided strap. The controller I use is the Tunematic ($289.95) version.

    I use the KD-T disconnects for all of my whips. In addition, I also have the capacitance hat with the quick              disconnects as well. I believe I have 4 whips of varying length.

I have had my Tarheel 300 for about 15 years. I have experienced no failures or breakdowns. The Model 75A  I have had for about 5 years. Again, no failures or breakdowns. I strongly suggest that you spend some time on the Tarheel site looking at the various mounts and accessories. There are some excellent units there.

If you have any questions, please contact me.

73,

Tom, WA7TBP

Re: Tarheel questions

Howard,
The antenna mount is very important. I suggest you call Tarheel for their recommendation. I got what they recommended. Also, consider power in vs power out on the 160. Ask Tarheel about that too. Probably not a great ratio, and there aren't that many 160 ops. Are you going to spend the night in your car on 160?

Yeah, that looks as if it would do fine.

I’d like to have 160M, sure.  Right now I’ve got no antenna that will do 160M.

My observation is that on HF, I’ve got perhaps a hundred QSOs on 80m, hundreds of PSK QSOs on 40m.  Thousands on 20m.  Many hundreds on 17m, 15m.  Dozens on 12m and 10m.  Zero on 160M, which I admit is partly to do with lack of antenna that would tune so I can transmit.  But I have listened and let my station run listening to 160M for PSK signals, and it has never seen one.  Not one.  So my interest in 160m is pretty much theoretical.

The whip for the Little TH II is 32” long.  The base is 16” long.  I can fit a 48” unit into my car *side to side* without breaking it down.  If I want better performance I can get the 56” whip, but I suspect I could also use a telescoping whip like I have for the Buddipole just as easily.

The base for the 300 and 400 is minimum 36” long and the whip is 72” long.  The combined length is 10’.  Sitting in the parking lot for a park in Granite Falls, running PSK on a laptop, with an antenna that’s 4 feet long is one thing.  Doing it with an antenna that is 10’ long is another thing.  Again I can use a telescoping 72” whip, but I can’t make that 48” long base of the 400 any shorter.

Mostly it’s the size of the thing for me.  I know everyone will tell you that size doesn’t matter and it’s all about how you use it.  But when you’re trying to fit all the gear into the back of the car, size matters quite a bit.

Ok so if you all won't talk me out of it, then talk into the right one.  I'm now thinking I can use my CB antenna mount to attach a Tarheel II. Yes? Also, Paul, can you help me with your decision to forgo 160M? I'm assuming it is all about the size.  Below is my CB mount (with a quick release that I would remove). Ideas?
