I made three WESTPACs on the Connie 78-82 with VF-211, and VF-24. And VA-146, VA-147 in A-7s, VA-165s A-6s, and VFP-63 RF-8s. My Balut eating, AFTA class leader from NATTC, Millington, TN. was in VF-211. Saw him again years later on the Lincoln, in VF-114, Aardvark, and VF-213 Blacklions were their sister squadron. I was Ships company AIMD/IM1/QA. LOL, . Those were the first three of the seven WESTPACs on three carriers. And a lot of water under the keel ago..... AT1(AW/SW) USN ret. 1977-1997

I don't know anything about the F-15 RADAR. But I would imagine it needs a Doppler mode to see the weather. Does it have a Doppler Mode?

It depends on its Duty Cycle........... Peak- and Average Power The energy content of a continuous-wave radar transmission may be easily figured out because the transmitter operates continuously. However, pulsed radar transmitters are switched on and off to provide range timing information with each pulse. The amount of energy in this waveform is important because the maximum range is directly related to the transmitter output power. The more energy the radar system transmits, the greater the target detection range will be. The energy content of the pulse is equal to the peak (maximum) power level of the pulse multiplied by the pulse width. However, meters used to measure power in radar systems do so over a period that is longer than the pulse width. For this reason, pulse-repetition time is included in the power calculations for transmitters. Power measured over such a period is referred to as average power. Duty cycle D = P = τ where: P = average power Pi = pulsed power τ = pulse width Τ = pulse-repetition time PRT The product of pulse width (τ) and pulse-repetition frequency (PRF) as the reciprocal of the pulse period (Τ) in the above formula is called the duty cycle of the radar system. The duty cycle is the fraction of time that a system is in an “active” state. In particular, it is used in the following contexts: Duty cycle is the proportion of time during which a component, device, or system is operated. Suppose a transmitter operates for 1 microsecond and is shut off for 99 microseconds, then is run for 1 microsecond again, and so on. The transmitter runs for one out of 100 microseconds, or 1/100 of the time, and its duty cycle is therefore 1/100, or 1 percent. The duty cycle is used to calculate both the peak power and average power of the radar system. For the performance of radar, an average power has more significance than the pulse power of the transmitter. Since the introduction of intrapulse modulation and pulse compression, there is no longer any proportionality between pulse power and maximum range. The Interference Blanker Unit (IBU) in the Hornet is what controls the TX/RCV time for all RF systems in the Hornet, or their Duty Cycle. Hoss

SARH missiles require tracking radar to acquire the target, and a more narrowly focused illuminator radar to "light up" the target for the missile to lock on to the radar return reflected off the target.[5] The target must remain illuminated for the entire duration of the missile's flight. This could leave the launch aircraft vulnerable to counterattack, as well as give the target's electronic warning systems time to detect the attack and engage countermeasures. Because most SARH missiles require guidance during their entire flight, older radars are limited to one target per radar emitter at a time. The F/A-18's AN/ALQ-126 Deception Repeater has a circuit card in it called a Pulse Density Demodulator. It looks at a specific area (window) of the received TTR (target tracking RADAR) signal. Once the missile launches and the booster falls off, it exposes an antenna, the TTR will start sending guidance pulses to the Missile. The PDD card sees this and knows the missile is in the air now because those pulses are moving quite nicely in our window, at this point we start transmitting deception pulses back to the TTR on a one-for-one basis. For each pulse that the 126 sees it will transmit a deception pulse at a higher amplitude to bury the actual return in noise. Remembering the 126 once moved from RCV to RPT at Fence In, will only transmit once the received signal strength exceeds a predetermined threshold, and will stop repeating when it exits that signal strength threshold on the way out. Most SAMs, Airborne TTRs, and DECM systems transmit at 1,000 watts or 60 dBm, as does the AN/ALQ-126A/B, and F/A-18 RADARS. For every +3 dBm, the signal strength doubles, for every -3 dBm it halves. Sense, On and Snap, Off (Repeater On/Off) is 29 and 39dBm. Does that help? My leg to stand on........ AT1(AW/SW) USN ret. 1977-1997 DECM Technician.

It's too modern and should reflect the period when most of the conflicts took place, the late 50s to late 70s. Cities and airfields are too modern for that period. And that's just my two cents worth.

I use a 10cm curved extension, with F/A-18 stick, and it went from the old WartHog base right onto the new AVA base with no problems. So, I imagine the new offset will work on the WH base too.

Get yourself one of these off ebay. And yes remove screws one at a time, put a small bit of loktite on them and re-install. Remember do not over tighten fastners with no torque value. 30-60⁰ past self rising torque, not Magilla Gorilla tight.

I found that out real quick, and put two more washers (one already installed)on the screws. That fixed the screws bottoming out. I did that before I ever screwed on the stick. Probably why I never heard the clunking. MT put out a plate specially for the AVA. I doubt its any thicker gauge than the WH base. I'm good with the extra washers. When I remember, I can pull one of them, maybe M5, and get some shorter ones. @Chicki I got it from a guy here on the forums, K51. He has numerous flight controls to order. I finished the console I made to house the extra stuff I came across. Now to hook it up and get it all working, and re-do, everything. It's a good thing I'm bald!

The P-38 Lightning is a must have for the ETO and PTO maps. I'm sorry but the F6F wasn't used to escort B-17s off the islands, but P-38s were. I believe the Corsair is vapor ware. We'll have a true Pacific game coming soon enough. I'd lay money it will be finished and on the net before anything of any substance comes out of any DCS developer for the PTO. We didn't need the South Atlantic, or the Kola map, or a MODERN Sinai map. A time period correct Vietnam and Korean Peninsula maps for Early and Cold War plane sets is a very soon must have. Ctrl An A-6E and A-7E and F-8. F9F Panther, F4U-4, Skyraider, and Sea Fury are nice additions for these maps..... JM2CW

Adjusting Jester Menu Position for Multi Monitor setups
_Hoss replied to shauntoastr's topic in DCS: F-4E Phantom
Instead of Jester, they should have called the guy-in-back, Phester. That way we all know we're talking about a Wizzo without having to say which one. Yeah I know! -
Amazon says mine should be here Thursday. Amazon isn't shipping them until the 22nd. I need to finish my left console and get ready to fly again. Photo is missing the K51 trim box to the right of the throttle. It used to look like this, that is the K51 trim box behind the throttle.

Announcing the Stand-up of the vVFA-97 Warhawks!
_Hoss replied to AMEDooley's topic in Jets Squadrons
Congratulations on starting your outfit. I was in VA-94, 85-89. I'm still just 12 miles down the road from the back gate at the base. I retired from the Navy in 97 and worked for Boeing in VFA-125, now VFA-122s hanger Mod. I retired from Boeing at the end of June 2021. Wishing you Fair Winds and Following Seas.

DCS F-4E Phantom II Release Date Announcement- May 21st 2024
_Hoss replied to IronMike's topic in DCS: F-4E Phantom
Bitchin', Amazon will be shipping my TM AVA base the 22nd.... We'll find out if both are up to their hype..... -
I imagine the cities are too modern, much like the Sinai map. Being able to replicate WWII, much like a modern Cairo fails for 1950 to 1972 time period cities and airfields. I hope if and when they make a Korean peninsula or Vietnam map they make them era appropriate..... and not modern. Or one of each, like a Marianas pair for each era.

Straight deck only......

Well then...... we need the Corsair finished, we need a Hawker SeaFury, Meteor, F-84, F-80, AI B-29, and most importantly an F9F Panther and A-1D Skyraider.... and a Essex Carrier to operate them on. We have the Mustang, Saber and Mig-15. Now a relevant Korean map 50's and Semi modern eras.

The first pictures I saw of it it had a baseplate like the Warthog stick.

F/A18E/F Super Hornets block 1 and BLock 2 E/F ( lot 26)
_Hoss replied to Kev2go's topic in DCS Core Wish List
I retired as a Aviation Electronics technician, First Class, or Avionics tech, I worked on the DECM out of the old A-7Es, A-6Es, then the F/A-18C/Ds. I did three WESTPACS as ships company on the Connie, 78-82, two with VA-94 (A-7s) out of NAS Lemoore, on the Enterprise, 85-88, and two more as ships company on the Lincoln, 93-97, where I retired out of Everett, WA. and came back here to Lemoore where the wife and kids were.

If I'm not wrong about the year, the NAVFLIR started being replaced by the ATFLIR around 2003.
