I just sent my ARR pre amp back to ARR for repair for the 3rd time !
(pretty sure I did not tx through it )
What are people using for pre amps. I only see the Mirage as an alternative.
Any other choices. I'm kind of disappointed in ARR products.
Is there a pre amp that you can tx through preventing accidental frying?
Any thoughts appreciated

I've been using the SSB Electronic preamps for years now. Thye handle
the ~50 Watts from my FT-847 just fine.

I use preamps from SSB and have been very happy with them. Another popular
brand is Landwehr, as is ARR (with which you're having trouble).
My radio is an Icom IC-821 which provides power via the coax when in
receive-mode. The radio automatically removes the preamp power before
keying the transmitter which protects the preamp. Other Icom and Yaesu
radios have this feature; the Kenwood TS-2000 may also support this.
Note that ARR also sells preamps with RF sensing with either a 25 watt or
160 watt rating.
Good luck.

Ted,
Not without relays to bypass the preamp when transmitting. Several
outfits make preamps with RF detect and internal relays but be
careful not to exceed their RF power ratings. ARR make a fine preamp
and I have used them for years. The mgf-1302 is the standard device
in them but have become scarce (hard to find). Not sure what ARR is
using as a substitute, but you could stock up on a handful and do
your own repairs.
I have been the beneficiary of a couple dozen H-J Fets (NE334S01)
that drop into the ARR and have half the NF (typ. 0.24 dBNF). They
are smaller devices so a bit harder to handle. I just installed one
in an old P144VDG ARR preamp and had only to substitute the 100-ohm
resistor with a 270-ohm to supply Vds=2.4v (mgf-1302 take Vds=4v).
I will be installing it on my 2m-eme array in a couple days and will
see how it plays.

Hello Ted,
You didn't mention whether you had an ARR pre amp with the RF sensing.
I have been using my ARR pre amp for 15+ years outside (with a cover). I
open it every year or two and the inside still gleams. The exposed toggle
switch is showing its age though.
My recommendation is to get the pre amp with the RF sensing. My opinion is
that there is no if you will inadvertantly transmit through it, just when.
73,
Gould

Hi Ted,
I have an ARR 160 watt RF sense unit and it works great.
I also have a couple of SSB RF sense units and they
work great too.

Since I have a dozen NE334S01, I can repair a few ARR 144 & 432
preamps for others.
So here's the deal. You ship to me in a small flat-rate Priority
Mail box (cost you $5.20) and include $30 for repair plus return
shipping. You can either send a money order or use PayPal for
quickest turnaround (a check will have to clear the bank before
shipping back). NO VISA/Mastercard/other credit cards (sorry).
Typically, priority mail takes 3-5 days to reach me. I will make the
repair within 48-hours of receipt. So turnaround could be as little
as 8-days or as much as 12 days (not including Sunday or Postal Holidays).
I can verify operation (gain) but not able to measure noise figure or
sensitivity. I can only warrantee workmanship that the preamp is
functional for 30-days. No warrantee for transmitting into the
preamp or reversing dc voltage connections or dropping off your
tower. I will not accept preamps that have been previously repaired
by other than the manufacturer. Replacement of other components
beside the Fet are at cost+15% (e.g. bad voltage regulator, broken
feedthru, etc.). Not responsible for loss in shipment so include
insurance if you desire that. If preamp is unrepairable, only cost
$5.20 shipping back to you (balance will be refunded).
This offer is good until I run out of current stock of NE334S01 devices.
PLEASE CONTACT ME via e-mail before SHIPPING!
For comparison, ARR will charge $22.50 plus shipping UPS. I can not
do Factory Warranty work; contact ARR for that.
If anyone objects my sending out this e-mail - then don't read it
(LOL). This is not a commercial business - a ham helping other hams!

As others, SSB Electronics model that is RF switched. I *have* transmitted
100+ watts into it, though not on purpose, and it works just fine. I got
the RF switched model as a "just in case" bit of insurance, and am glad I did.
It's been reported here a few years ago that sometimes there's a little
"burp" of RF that squirts out when a transceiver is powered up. Seems
unlikely , but if so, maybe that did it?
If I recall, the discussion was about people frying their AO-40 S-band down
converters by accidentally transmitting into them. An somewhat less certain
recollection is that someone came up with a simple circuit that would clamp
the RF to a more forgiving, if not totally safe level. As an alternative to
an RF switched preamp model, perhaps a stroll through the archives might net
a different solution.
Good luck,
Greg KO6TH

I think DEMI made those "protectors". I never modified my K5GNA
downconverter, so my FT-847 was tuned to 123MHz to use it, and it
wouldn't transmit there.

What Greg is describing is an RF sensed high-power
attenuator. Downeast makes two products that can work to do this:
One is the AOS-144 ( $80.00) which switches RF thru a 50w attenuator
to a factory adjusted level from 10 up to 100mw output for driving a
transverter. The receive side is passed thru to a common SO-239
connector which is connected to the radio. To use it solely for a
preamp a 50-ohm resistor can be tied across the BNC transmit output
connector. This would be used in conjunction with TR relay for
unswitched preamps like the P144VDG.
They also make the SSBT ( $65.00) safety switch bias-tee which might
be more appropriate. It provides dc voltage to power the preamp over
the coax line and senses RF for protection up to 50w. Again one
would need TR relays for bypassing the preamp if you want to also use
the antenna for transmitting.
But if you just want protection for a dedicated receive preamp either
would work without need for a relay.
I know that 100w was mentioned, but these probably would withstand a
momentary application of 100w such as the turn-on "burp" that some radios
have.

Nick,
Yes. If you set the Flex emulation to TS-2000 it works, somewhat. For
instance, the SATPC32ISS works fine as far as controlling the rig. The
problem is that while the rig hardware is full duplex, the existing Flex
software does not support the TS-2000 satellite/full duplex mode. There are
some other issues such as the FM not working quite right. Flex is slowly
working through these issues, and when the PowerSDR version 2.1 is available
it should be great satellite rig. Flex is using SATPC32 in their testing,
so it WILL work Real Soon Now.

Ahhh another AO-40 comment.? I used a old and still have in operation an old
TS-700A? 2M xcvr with the tx disabled.? This was, and is my designated S
band receiver.? Speaking of S band when will AO-51 be back in that mode.? If
even for a few days, it's fun to play with that stuff.

As others, SSB Electronics model that is RF switched. ?I *have* transmitted
100+ watts into it, though not on purpose, and it works just fine. ?I got
the RF switched model as a "just in case" bit of insurance, and am glad I did.
It's been reported here a few years ago ?that sometimes there's a little
"burp" of RF that squirts out when a transceiver is powered up. ?Seems
unlikely , but if so, maybe that did it?
If I recall, the discussion was about people frying their AO-40 S-band down
converters by accidentally transmitting into them. ?An somewhat less certain
recollection is that someone came up with a simple circuit that would clamp
the RF to a more forgiving, if not totally safe level. ?As an alternative to
an RF switched preamp model, perhaps a stroll through the archives might net
a different solution.
Good luck,
Greg ?KO6TH
