Here are the V2 MINIMUM specs.....

Voltage = 30VDC...They will work fine on 26-28V with only about a 5-10W reduction in power.

Maximum Input = 6W.

Gain = 10db min.@ 1db compression.

Output = 70W ± 0.5db @ 5W input.

Current = 7A max.

Bias activation = 7ma to ground @ 30V.

NO T/R SWITCHING! You MUST provide your own EXTERNAL T/R relays. HERE FOR RELAY CONNECTION INFO

Connectors = N Female in and out.....Power via spade lug terminal strip.(identical to 902 amps)

Duty Cycle = 100% CW Keydown @ 50W output with fan.

Devices = BLF1046 X 2.

Device Combining = 90 degree ring combiners by AD6IW

Price Reduced!! $220 including shipping to lower 48........seem like a lot? Check out DEM's 65W amp!!

These are class AB, NOT class A like DEM's amps.

These amps are high Q and tuned for the "weak signal" portion of the band (1296) but will work in the satellite portion of the band (1268-1270) at about 10-15W reduction in output without retuning. Re-tuned for the satellite 1269 portion of the band, they average about 70W output. 65W minimum. When tuned for AMSAT, the output at 1296 will be 50-55W. If you would like it re-tuned for AMSAT, just let me know when ordering. The biggest difference is INPUT RETURN LOSS. It changes considerably with a 28MHz shift.

They will also work excellent as repeater amps in the 1280 area at 50W continuous output with a small fan. They are NOT recomended below 1260 MHz.

Here are the "typical" power specs @ 30VDC, amplifier cold into a load @ 1296MHz.

1W in = 20W out.

2W in = 40W out.

3W in = 52W out.

4W in = 65W out.

5W in = 72W out.

6W in = 75+W out.

Recommend running at 5W drive. At 28VDC, the output will drop less than 10W @ 5W drive. They will easily handle 6W input, but begin to saturate.

These are built from surplus FET's. I have a lot of them, but there will be a limited quantity. If they become popular, we may develop a new amp down the road based on the devices but they probably will not be as cheap!

These are modified surplus cellular equipment. They contain NO T/R switching!!

Specs......

POWER = 135W ± 0.5db out with 0.8-1W input. (You may notice I reduced the power rating slightly as a cautionary measure since specifications on the devices are unavailable and I have blown a few in the tuning process)

INPUT = 1W.....Saturated at 1.3W. Each amp varies slightly in gain. A data sheet will be supplied with each. Some reach full power at 750mw input and are fully saturated at 1W.

Voltage < 28VDC....MAX!!

Current = 13A.

Size = 4" X 5.5" X 14". (HxWxD)

Power connector = Spade lug terminal strip.

RF Connection = N Female.

LED on front panel to indicate TX mode (bias on).

PTT = Ground to activate bias. Current = 15ma, 28VDC on bias connector when open.

NO T/R SWITCHING! You MUST provide your own EXTERNAL T/R relays.

DUTY CYCLE = 100% @ normal amateur SSB/CW service (with good airflow).....For FM/WSJT, recommend reducing output to 100W and cooling with a fan. 100% key down @ 70W output ...fan required!.

PRICE = $150 includes shipping in the lower 48.

Other info.....

I have tested and tortured these amps and here are some notes pertaining to their operation.

YOU MUST BE ABSOLUTELY POSITIVE that your power supply will not spike anywhere near 30VDC!!! These devices are NOT replaceable and WILL FAIL at or near 30VDC!!! I have seen 200W out at 29.5VDC, BUT when I unkeyed, the power supply jumped to 30.1VDC and the device flashed over and destroyed itself. Play it safe..........stay at 28V.

I left one keyed at 120W for a while, and they get pretty HOT....FAST! Use a fan if you are going to torture these. Normal SSB service does not affect these any more than a 150W Mirage 2m amp.

PLEASE keep the drive below 1.3W!!

Don't ask what type of devices are in these......they are a specially built device for Spectrian and I have still not been able to get any info on them. All I know is they are a "tripple" bi-polar transistor. If I ever get specs on them, I will post it here.

They are a little different design internally and MUCH more tolerant to voltage variations with replaceable transistors. They use the boards shown below and look identical to the 1W version shown above on the outside. The output is 130W max. They will also be a little cheaper, $130.

INPUT = OUTPUT @ 28VDC

10W in = 80W out....100% CW duty cycle at this power level with a fan.

15W in = 120W ± 0.5db out.

Max output = aprox 130W...recommend 15W max drive.

Max allowable voltage <29.0 VDC.

Current @ 120W = 8A @ 28V.

Gain = 9db ± 0.5db

Bias activation = 14ma to ground @ 28V.

NO T/R SWITCHING! You MUST provide your own EXTERNAL T/R relays.

Want to "do-it-yourself"?....I have avail the leftover 130W 902Mhz boards that have had the driver removed. these come complete with simple instructions on how to connect RF in and out, activate bias and minor tuning. They require 28Vdc and 28Vdc for bias (on board) and 15W drive for 130W out. These are untested but guaranteed to be OK. Price is $30 for the board or $40 with the matching case/heatsink. No connectors or power connections included. The boards bolt directly into the case/heatsink with 4-40 screws(not included) and some strange self tapping hollow hex screws that I will provide. The cases are identical to the 902 and 1296 amps. Devices are BLV958P X 2..... The circulator and most of the stuff at the lower left is not used. The cases do NOT have power or N connectors installed. They will look like the 902 15W drive amp above when finished. You just provide your own connectors and switching transistor to turn on bias (TIP-30C) and you are on the air. Little or no tuning required. It takes me about 3 hours to put one together with very crude tools! Contact me for more info. Click here for instructions!

I am currently out of LDF5 Andrew 7/8".

I have a few short jumpers (2-6') and some longer lengths of Andrew 1/2" "superflex" cable.

I have both "N" and "DIN" female connectors for the above coax types, but prefer NOT to sell separate from the coax, with the exception of 1/2" "superflex"....I have a lot of those!

Unless you wish to pay the high shipping fees, most of the hardline will be "pick-up" or if you wish, I can bring it to either the get-together at Mike's place in Fresno or Larry's place in Vacaville.....I live near Placerville,CA.

Email me for lengths, details and prices.

I have a few of the 7 pin accessory jack plugs for TE Systems amplifiers. They have NO covers, just what you see below. I have had good luck covering them with shrink tubing. They cost more to ship than the price of the plugs, so try and catch me at one of the local swaps at the M² plant in Fresno, Larry's in Vacaville or one of the breakfasts in W.Sacramento. $2 each or $5 shipped.
