| Reviews Summary for Ten-Tec 715 RF Speech Processor |
|
Reviews: 24
|
Average rating: 4.5/5
|
MSRP: $249.00
|

Description: Model 715 RF Speech Processor is a high performance true RF-type speech processor designed to operate with most modern HF Amateur Radio transceivers. RF speech processing is a superior system to the traditional AF clipping, AF compression, or RF compression found in a typical HF transceiver for achieving the highest ratio of average-to-peak power from an SSB transmitter.

The Ten-Tec 715 speech processor can be a helpful tool in giving your speech a bit more punch. It is not a cure for a very weak signal or an inefficient antenna, but it gives your voice signal substantially more punch. You can easily overdo it. One must use it carefully and and sparingly, or it will spoil the signal and cause significant distortion, but it is effective at giving your signal more power.

It's microphone dependent

It is definitly microphone dependent. It will not work on broad mics like a Heil Pro as stated elseware here. It does what it says on a stock hand mic. or a Heil Dx type. A Watt meter or a scope tells the story. It gives about a 6 Db increase in your average power output. If you want to punch through a pile up or noise with a narrow mic it will do the job. Not to be used in a rag chew session. Poor audio.

Great peice of equipment

I got won this little toy at the Huntsville Hamfest in 09 and the guys in the TenTech booth was VERY helpful!!! I brought it home that night hooked it up thru the Rig Blaster Plus using an ICOM stock mike and no joy AT ALL!!!. Reading the reviews I read the with ICOM mikes DONT BOTHER!!!! The TenTech person at the hamfest said the same thing. I hooked up a stock mike from a Kenwood TS-430S and wala it work fine. Once you get the passband and proc gain down and the tentech guy made it clear to only have the meter get to 6 and not all the way up it worked great on my IC-718 and with a rig blaster the any mic to any radio is the best!!!. I just was given a IC746 and pluged the tentech to it and wala perfect audio,

I've used this gem since Nov w/o issues on my
IC-7700 & ALPHA 87A .
The reason I'm writing now is to relay a comment by
JY4C indicating how easily I cut through the pile
up !! He was very interested in my equipment !!
One caviot it DOES NOT WORK WELL WITH BROAD MICS (
Heil Goldline on wide ect .) !!
Tnx Ray KCIMR

follow-up

i've also had the "freeze-up" problem with my audio. it was resolved by simply turning the "PASS BAND" adjustment. contacting TenTec with this concern, i was told it was a software problem that's being worked-on. second, i initially used the 715 with my Kenwood TS-570DG (as reported in my 1st review). when i changed cables and tried it with my Yaesu FT-950, audio was horrible. this was user error, as i assumed that the adjustments on the 715 suitable for the TS-570DG would be a good starting point for the FT-950... wrong! the Yaesu requires so little drive that the "PROC LEVEL" (on the back of the 715) has to be dialed waaaaaay down. in fact, b-a-r-e-l-y setting it above minimum is plenty! in this range of the potentiometer, however, adjustment is pretty touchy. that was disappointing.
so, in summary, it has worked well with my TS-570DG. it's "OK" with my FT-950. i'm yet to try it with my IC-7200.
i'd have 2nd thoughts about buying it, had i known what i now know.

Compatibility Problems with Icom
|
Time owned: months
|
Hearing great things about the Ten-Tec 715, I ordered one with the hope that it might improve the average output on my Icom 756 Pro III. Unfortunately, it didn’t work out. Using the Icom SM-20 desk microphone, the Ten-Tec Processor wasn’t as clean as the internal processor in the Pro III and did not boost the average power output as much as the internal processor. To make bad matters worse, the Ten-Tec processor would freeze up intermittently, resulting in no audio whatsoever. Thinking it might be RF getting into the processor, I turned the RF output on the Pro III all the way down. The processor still froze.
I called Ten-Tec's Service Department and spoke with Larry Worth who was extremely helpful. He gave me several things to try in order to solve the problem. When those ideas didn’t work, he sent me a second processor to see if that would solve the problem. The second processor froze immediately and I couldn’t even get it on the air. I returned both processors.
This was my first purchase of Ten-Tec equipment. Although this particular piece of equipment didn’t work in my particular situation, I was very favorably impressed with their level of service, patience, helpfulness and willingness to go the extra mile to take care of the customer. They are an excellent company.

Beware
|
Time owned: 0 to 3 months

Don't be fooled by the BANDWIDTH control. I hoped that for once, I could select DX plus strong, good audio. It does not allow enough lows to be dialed in - screaming DX'r sound, all the time, very little useful bandwidth control capability. No reason to even have the knob.
I returned it. It sounds worse that my DX engineering RF processor on my KWM-2A. Mind you, it is a traditional RF processor that does brings up your average talk power as claimed.

Great Cheap Power!!

Santa brought one of these to the shack this year. Got it up and running in no time and tested it out with several other stations. This little box works as advertised. On one test I lowered the power out to the minimum possible and the other station could not hear me with the 715 out of the circuit. When I turned it back on he was reading me at S5 on the meter. Tested it on a couple of DX stations and they came right back to me with good signal reports. You sacrifice a little audio fidelity (you should expect this) but all stations reported that it was very easy to listen to and not to sharp or raspy. I'm very pleased and it makes my FT-1000MP MK V really rock on SSB Great piece of gear and I highly recommend it. I may not every have to use my amp again hi hi. The only down side is that you need a Ten-Tec or Yaesu mic for it or you have to rewire a mic per the manual. On the plus side I can use my MD-100 mic on my Kenwood TS-2000 and FT-817 now (purchased extra cables).

Great product

This is quite an extraordinary device, it does everything stated, I recommend it highly.
My only negative comment is their reference to a 110 volt power source in their literature. I contacted the sales department to inquire if they did indeed provide a wall-wart rated at 110 volts but they did not reply. The problem is this, we have not used 110 volts in this country since the 1940s, the standard voltage is 120 volts with some utilities serving 125 volts. So obviously a 110 volt wall-wart running on 120-125 volts would be needlessly stressed. The good news is that the unit provided is rated at 120 volts. I find it surprising that electronic engineers lack even the basics of electrical engineering. The ARRL was in this position until the early 1990s when I told them that in QST and the Handbook they were referencing a voltage not in use along with obsolete receptacles and plugs. That letter was like nuking Newington, they were stunned to say the least.

Much Happier Now

After talking to several others and working thru the adjustments on the air, I think I've hit the "magic" combination that lets the 715 work with my station set up. I'm anxious to give this little box a shot in it's intended conditions to see if it improves my signal in pileups and where the signal strength is low but the audio boost provided raises me up out of the "grass". It looks promising!
