In the credit-where-credit-is-due department, Powerwerx responded to my emails this evening. They are shipping me the correct cable at no charge, and have refunded the money i spent for expedited shipping on the incorrect cable. They also stated that they are reviewing quality control procedures with an eye to minimizing the chance of a repeat.
Doesn't it make you feel like a jerk now? It was an honest mistake, the company made good and you just had to smear them like a fool. Sorry, like you, I call it the way I see it. Maybe next time you will think before you open your mouth.

Resistive splitters also have next to nil port to port isolation. That one I showed will work through HF into VHF, around 30db port to port isolation, and if you choose the right core, it will go into UHF at the loss of HF. I reverse engineered it from a commercial one I had around, but I was guessing at the core material. The 75 ohm ones in the old TV antenna preamps are pretty much the same, but I think they use a higher freq core for VHF/UHF.
Absolutely agreed. They are useful in wide band applications.

The manufacture of these circuit cards is automated using pick and place machines. When programming the pick and place machine, the programmer simply programs another "resistor" for the jumper so no special handling is required with a piece of wire.

You should also be aware that there are resistive splitters out on the market. I don't recommend them as the resistive loss is 3 dB instead of lossless in a Hybrid splitter. Resistive power dividers are easy to understand, can be made very compact, and are naturally wideband, working down to zero frequency (DC). The two-way resistive splitter suffers 10xlog(1/2) or 3.0103 dB of real resistive loss. Accounting for 3.0103 dB real loss and 3.0103 dB power split, the net power transfer loss you will observe from input to one of two outputs is 6.0206 dB for a two-way resistive splitter, so they are often called 6 dB splitters.

I couldn't agree more. I couldn't find an IMD spec on the Anan 100D so unless he tested it himself, he really can't say anything about IMD one way or another. Sorry....... He is starting to sound like a skipping record.

Look at one of the latest:
--from the Amazon feedback--
1 out of 5: "item arrived witout extra battery as advertised, no note from seller. I contacted seller who said they would send the battery. 3 weeks later no battery, filed a claim and seller tried to get me to drop the claim before i received the battery. THIS SELLER IS SHADY, I WOULD AVOID. "
Sounds normal--for RadioMart!
For once we agree on something. This guy is a real dirtbag!

You could not be more wrong. Ever hear of ground loops or ground currents? They are a source of noise. It's recommended to use one point for ground for a reason and it is based on factual data.  In YOUR opinion. Daisy chaining is not 'looping' ground connections. I suppose you think a ground halo is 'looping' grounds too. Many stations use several ground rods to increase their protection, especially commercial stations--and most of those use a building ground halo. I think we had this discussion on another thread with you before, and I'm not going to go through it again. It's sufficient to say that you had little idea what you were saying before--and still don't. I am going to chalk up your response to the fact that you are not too bright. Ground loops have absolutely nothing to do with looping ground connections. Ground loops refer to a current, almost always unwanted, in a conductor connecting two points that are supposed to be at the same potential, in this case ground. That is why you want all of your grounds to connect at one place, so they are all at the same potential. Any difference of potential across a conductor will allow a current flow. The ground currents can manifest themselves as noise. Kapish?

Just bond it to the closest ground rod. You've already taken adequate grounding measures of using three rods, now keep the bonding runs as short as possible to minimize resistance. I believe you'll find that the theory of having one central ground rod that everything is connected to is just that--a theory. As long as all ground rods are bonded together and bonding runs are kept as short as possible, your grounding system will work as you intend.

I found the LIDO mounts and i was very pleased that someone makes this kind of mounts. I was ready to order till i found this topic!thank God!!!this must be the worst mount company E V E R!!!
Thanks to all fellow hams for the information about this company.
73's
I ordered my Lido mount from HRO and had no problem. They are great products, but make sure you order through a distributor not direct. Guy (K2GWK)

I have started to build my K3 this weekend. I am about half way done. I am very impressed with the quality of this beast and how it fits together so well. I hope to have it finished this coming weekend some time. I have the P3 assembled already and have my eye on the K3 Line antenna tuner and power amplifier. Nice job on the video!

Well, I may as well throw my recommendation in the ring. I see a lot a Drake TXx, RXx and TRx rigs for very modest amounts of money here on eHam and on Ebay. These are excellent rigs and much more easily repaired than some of the older transistor rigs. If you are willing to get your hands dirty I bet you can find a whole Drake station for around $500 to $600. That Drake audio is to die for.

eHam Forums / Elmers / RE: DSP NOISE BLANKERS--THEY SUCK!..
|
on: April 18, 2013, 01:11:44 PM

Whilst not a true DSP (I believe it's an ASIC) I have had good experiences with the devices made by BHI. Their main purpose is to pull voice signals out of the noise so one of these will not be your solution if you're a CW man.
Tanakasan
That device is an audio noise filter and will help with background hash (white noise). Noise blankers will only get rid of impulse noise (car ignition etc.). BHI does not make a noise blanker to my knowlege.
